condensationpolymers
condensation polymerisation is where 2different monomers with at tea
functional groups react together a link is formed and water is eliminate
3mtianiffyeptesrimines the type of polymerproduced
polypeptides found in proteins
polyamides formed byreactingdiaminesand dicarboxylicacids
is polyesters formed by reacting a diol and dicarboxylic acid
polyamides
amide link formed when dicarboxylic acids react with diamines
dicarboxylicacids and diamines have functional groups either side
which allow chains to be formed r amide link

polarity in condensation polymers
condensationpolymers have polarbonds causedbyC O
nd C N bonds
these polarbonds allow chains to interact with each

Hydrogenbonds exist between the polymerchains as well asdipoledipole and
an der waals forces makes condensation polymersstronger than addition
