" Polymerization technique is defined as the fundamental process by which low molecular weight compounds are converted into high molecular weight compounds (means, polymers) ".             " Chain-growth polymerization reaction " also known as " Addition polymerization reaction ". In this polymerization reactions, monomer molecules bond to each other to form a larger molecule called a polymer, without removing any of the smaller molecules as a byproduct. An addition polymer is a very long organic molecule formed as a result of an addition reaction between monomers with unsaturated carbon-carbon bonds.  ☛ The kinetics of addition polymerization proceeds according to the chain polymerization mechanism that occurs in three basic steps; 1) Chain initiation 2) Chain propagation 3) Chain termination Since, addition polymerization occurs in four ways (free radical/cationic/anionic/co-ordination Polymerization) therefore all its types follow the same kine...

Chain-growth polymerization reaction is one of two processes to convert a monomer molecule into a polymer. Chain-growth polymerization reaction is a polymerization technique where unsaturated monomer (means containing double and triple bonds in their structural formula) molecules add onto the active site on a growing polymer chain one at a time.           Depending on this active site present on the growing polymer chain, there are three types of addition polymerization: free radical polymerization , ionic polymerization , and coordination polymerization . Out of which, coordination polymerization is rarely observed, so we will not study about it. Thus, Let us study briefly about all these types of addition polymerization reactions; (A) Free radical polymerization – Free radical polymerization is defined as a type of addition polymerization in which the active centres are free radical. It is denoted as "M•". Since free radical polymerization is a type of ad...

Polymerization is a process in which thousands of smaller molecules called "monomers" join together to form larger molecules called "macromolecules/polymers". They have high molecular weight. Several different categories of polymerization reactions exist, but the most notable of which are: step-growth polymerization and chain growth polymerization.  Chain-growth Polymerization   Chain-growth polymerization reaction is one of two processes to convert a monomer into a polymer.  " Chain-growth polymerization reaction is a polymerization technique where unsaturated monomer (means containing double and triple bonds in their molecular formula) molecules add onto the active site ( It can be radicals, positive ions and negative ions etc.) on a growing polymer chain one at a time ". Chain-growth polymerization reaction also known as Addition polymerization reaction. Monomers used in chain growth polymerization reaction; E thylene/ethene [CH₂＝CH₂] Propylene [CH₃–CH＝...
