Study Notes

Addition Polymers vs Condensation Polymers

Addition polymers are formed by joining together many shorter molecules (monomers) to form a long chain molecule, with no byproduct.
Condensation polymers are formed by joining together many shorter molecules (monomers) to form a long chain molecule, with a small molecule (e.g. water) as a byproduct.

Characteristics of Addition Polymers

Made from monomers such as alkenes
Examples include poly(ethene), poly(propene), PVC
Non-biodegradable due to the absence of polar bonds in the main chain (all bonds are C-C)

Characteristics of Condensation Polymers

Made from monomers such as dicarboxylic acids with diols, dicarboxylic acids with diamines, amino acids
Examples include polyesters (e.g. terylene), polyamides (e.g. nylon, Kevlar)
Biodegradable due to the presence of polar C-N or C-O bonds in the main chain

Polyamides

Formed by the reaction of a carboxylic acid with an amine, releasing water
Can be formed by the polymerization of amino acids, which contain a carboxylic acid group and an amine group
Examples include nylon 6,6, formed from 1,6-diaminohexane and hexane-1,6-dioic acid

Polyesters

Formed by the reaction of a carboxylic acid with an alcohol, releasing water
Examples include terylene, formed from ethane-1,2-diol and benzene-1,4-dicarboxylic acid
