What is meaning of 9 7 and 4 in carbopol 974P?
In the context of Carbopol 974P, the numbers 9, 7, and 4 refer to the molecular weight and viscosity characteristics of the polymer. Specifically, Carbopol 974P is a crosslinked polyacrylic acid polymer with a specific grade that indicates its properties, such as the degree of crosslinking and the resulting performance in various formulations. The numbers help differentiate between various grades, which have different thickening and stabilizing abilities in cosmetic and pharmaceutical applications.
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.
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 takesplace in a step wise manner.In addition polymerization monomers react to form polymers and there is no biproduct formation.In condesation polymerisation, byproducts are formed in every steps called as dimer,trimer.tetramer etc...
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 of Formation of Polymer from its Monomers is Called Polymerization.
