It is difficult to control precisely, but in order to make polymers of a specific length using a free radical chain reaction, there are three steps: initiation, propagation and termination. To stop the chain reaction (termination) you need something to quench the free radicals so that the reaction cannot continue. This can be done by either adding a radical-quencher -- often a large molecule that can stabilize a free radical thus removing its high reactivity -- or the reaction can also be terminated because a limiting reactant has been consumed. While these methods will stop the reaction at a specific point in time, they don't guarantee that all of the polymer chains will be of equal length (there will be a distribution of lengths around some average value, although that distribution might be wide or narrow depending on numerous factors). Generally to obtain a polymer chain of one specific length, further purification and separation techniques are required.
To maintain a specific chain length in free radical propagation, a chain transfer agent can be used to transfer the growing radical to another species without adding or removing carbons. Another method is to carefully control the concentration of the reactants to limit the number of propagation steps that occur. Finally, terminating the reaction before the chain length grows beyond the desired length can also help maintain a specific chain length.

What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
What is impulse propagation?
Impulse propagation refers to the transmission of information or signals along a biological or artificial network, such as nerve cells in the human body or electronic circuits. In the context of nerve cells, it typically involves the propagation of action potentials along the axon of a neuron to transmit electrical signals. Impulse propagation plays a crucial role in communication and coordination within biological systems as well as in the functioning of electronic devices.
What is underground runner in plant propagation?
An underground runner in plant propagation refers to a type of stem that grows horizontally underground, producing new plants at intervals along its length. This method allows plants to spread and propagate asexually by forming new roots and shoots from these runners. Examples include strawberry plants and some grasses.
Is length a scalar or vector?
Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
What does propogation of an action potential mean?
Propagation of an action potential refers to the transmission of the electrical signal along the length of a neuron's axon. This is achieved through a series of depolarization and repolarization events that allow the action potential to travel in a rapid and coordinated manner from the cell body to the axon terminals. The propagation process ensures that information is effectively communicated from one part of the neuron to another.
In optical fiber propagation loss is increases or decreases with increase in length of the fiber cable?
Increases with length and connections.
How do you maintain length when bowling in cricket?
To maintain length try playing a sport other than cricket.
The length of two legs of a right triangle are 3 and 4. What is the length of the hypotenuse in simplified radical form?
The length of the hypotenuse is 5
What is the hisrtory of radical in math?
It is believed that it arose as the measure of the diagonal of the unit square. By Pythagoras's theorem, the square of this length was 2, but when it turned out that this was not a rational number, it was expressed as a radical.
What formula is radical radius squared plus height squared?
It is the length of the slope of a right cone.
What tests do TSB-67 require from a field tester?
The attenuation test, the length test, the NEXT test, & the propagation delay test.
What is the distance of the diagonal path from one corner to the opposite corner?
in a square it is the side length radical 2
What is the length of the hypotenuse of a right triangle if BOTH legs measure fifteen cm?
15 radical 2
A square has sides which are each 30 inches how many inches is the length of the diagonal?
30 radical 2
How is radical used in real life?
In the simplest case, it is use to find the diagonal length of a unit square.
Length of an inch worm in millimieters?
There is no specific length of an inchworm.
