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
