Is condensation polymerization results in a polymer that is less massive than the two monomers that joined it?

yes because some of the atoms are eliminated from the monomers, usually a hydrogen from one and OH from the other to form water.

How do you find the area of a kite with dimerise area of 1.5 meters squared?
Dimerise refers to compounds formed from two identical molecules (cg monomer or polymer). That has absolutely nothing to do with the area of the kite. I suggest you review the question, check the spellings and resubmit it.
How thin films deposited using solution casting method?
In a nutshell, the process of producing thin films or membranes involves the following steps: a polymer solution or melt is forced through a die/coating machine onto a backing or inert support, such as a sheet of nylon or even cellulosic paper. The newly deposited film on its backing is then fed, in the form of a continuously driven sheet, through a treatment process specific to the application. Finally, the sheet is packaged for later use, often by rolling it back up. Here is a longer step by step description of the process: 1) polymer system is prepared. This involves the melting or dissolution of one or more polymers into a solvent system. This step may involve more complicated procedures than simply adding solids to a solvent or heating a solid until it melts. The specifics are ultimately determined by the application, the capacity and equipment available, and the 2) the polymer melt or solution is then fed through a die coating machine onto a backing of some kind. This is by far the most common process, and even when applications do not use a backing/support the film is still cast this way (later processing will peel it away). other processes exist, such a spin coating, spray coating, etc. but this method is the most widely used in industry for the preparation of thin films or membranes. This step is typically considered to be the most precise part of the entire process. The polymer must be fed at a constant, consistent, and reliable/accurate pressure, temperature, and flow rate. This must be achieved while depositing approximately 100-200 micrograms of polymer solution (ultimately about 20-40 micrograms of solids after the solvent has been removed) per square milimeter over a width of several feet and a length of many thousands of feet. A small scale operation should produce around 7,000 feet of membrane per day per casting machine, though it can be much much higher. 3) The newly coated polymer sheet is now treated by drawing the sheet through some collection of processes along a series of cylindrical rollers. Drying, heating or cooling, photo irradiation, doping (example: exposure to a dye, a particular chemical, a salt solution, etc.), pH balancing, and rinsing are common examples of treatment stages. 4) the sheet, now treated, is typically rolled back up for later processing. It should be noted that not all films require the use of backing or support in their application there are many applications which require that the polymer film be carefully peeled away from the backing at some later processing stage. As a side note, I will mention the following about this particular method of thin film casting: Its main historical application, and that which produced the most R&D and understanding of the theory underpinning this field of materials science, was the production of large quantities of Cellulosic (nitrate or acetate) film backing for use in chemical film. Unsurprisingly, Eastman Kodak held many of the patents and trade secrets related to this technology for many years, and they (Eastman Chemical Company) still operate as one of the main suppliers of cellulose acetate used for the production of membranes or films.
What kind of ball do they use in the game rugby?
The ball is classed as a torpedo shape, basically pointed at both ends. The American football was based on the original design . The size, weight and air pressure used to inflate the ball are governed by the NRL and IRB regulations. The are now a number of manufacturers of rugby balls the oldest being Gilbert of UK who produced the first balls used in the Rugby School Warwickshire England. They were made of leather outers with pigs bladder inside which was inflated to make the ball. They are now made of a synthetic polymer with a silicone inflatable bladder inside

What synthesis puts two monomers together?
Polymerization is the synthesis process that joins two monomers together to form a polymer. This process can occur through various mechanisms, such as addition polymerization, condensation polymerization, or ring-opening polymerization.
What reaction adds monomers to a growing polymer chain?
Such reactions are known as polymerization processes, they are of two types 1- addition polymerization and 2- condensation polymerization.
How does condensation polymerization takes place?
Condensation polymerization occurs when monomers with two or more functional groups, such as -OH or -COOH, react to form a polymer chain along with the release of a small molecule like water or HCl. This reaction involves the formation of covalent bonds between monomers through condensation reactions, leading to the growth of the polymer chain. The process continues until all the monomers have reacted or the polymer reaches a desired length.
What reaction forms monomers?
Polymerization reactions form monomers. Monomers are smaller molecules that come together to form larger polymer molecules through various chemical reactions, such as condensation polymerization or addition polymerization. During polymerization, monomers join together to create long chains or networks, resulting in the formation of polymers.
What has the author John K Stille written?
John K. Stille has written: 'Condensation monomers' -- subject(s): Condensation products (Chemistry), Monomers 'Introduction to polymer chemistry' -- subject(s): Polymerization
Is the polymerization of polylactic acid addition or condensation?
The polymerization of polylactic acid is a condensation polymerization process. It occurs when the lactic acid monomers undergo a condensation reaction, releasing water as a byproduct to form the polymer chain.
When monomers combine to form a condensation polymer another product is also formed Typically this product is?
When monomers combine to form a condensation polymer, another product that is typically formed is a small molecule such as water, methanol, or hydrogen chloride. This byproduct is released during the polymerization process as the monomers link together to form the polymer chain.
When synthesizing a polymer a condensation reaction is formed by the joining of monomers?
Yes, in condensation polymerization, monomers react to form a polymer with the elimination of a small molecule such as water. This reaction continues until all the monomers have reacted or until a termination reaction stops the process.
The products of condensation polymerization are a polymer and?
a small molecule, such as water or an alcohol. This process involves the repeated condensation reaction of monomers, leading to the formation of a polymer chain and the release of the small molecule as a byproduct.
Why is condensation polymerization known as step growth polymerization?
Condensation polymerization is known as step growth polymerization because it involves the repeated condensation reactions between monomers, leading to the formation of polymer chains through step-by-step reactions. This process typically results in the gradual elongation of the polymer chains in a stepwise manner, hence the name "step growth."
What synthesis is the polymerization process in which a water molecule is lost in the process?
The polymerization process in which a water molecule is lost is called condensation polymerization. In condensation polymerization, monomers join together to form a polymer while releasing a small molecule like water or alcohol as a byproduct. This type of polymerization typically involves monomers with functional groups that react to form covalent bonds and release the small molecule.
What is it called when monomers form polymers?
The process by which monomers form polymers is called polymerization. This involves linking monomer units together to form a larger macromolecule, known as a polymer.
