Condensation vs Addition Polymerizations
Condensation vs Addition Polymerizations + - Two sites (AB or AA + BB) give a linear polymer chain Step-growth mechanism Often afford a condensate by- product (monomer and repeat unit not equivalent) High degrees of polymerization ( molecular weight) are obtained only at high degrees of conversion of monomer Non-living except in a few cases |
What are the characteristics of condensation polymerization?
Two main characteristics of Condensation Polymerization Instead of double bonds, these monomers have functional groups (like alcohol, amine, or carboxylic acid groups). Each monomer has at least two reactive sites, which usually means two functional groups. 9.
What is polymerization in chemistry?
In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three- dimensional networks Polymerization 6. Types of Polymerization: 7. Addition/Chain Growth PolymerizationCondensation/Step Growth Polymerization 8.
What are the high degrees of polymerization?
•High degrees of polymerization ( molecular weight) are obtained only at high degrees of conversion of monomer Two sites (AB or AA + BB) give a linear polymer chain - + Polycarbonate via condensation of bisphenol A and phosgene; an example of an AA + BB polymerization
