Polymers are made up of small molecules called monomers.
Polymers which are formed by one type of monomer is called
homopolymer. Polymers are formed by more than one type
of monomer are called copolymers. Natural polymers are
biodegradable whereas synthetic polymer may or may not
be. Addition or chain growth polymerization involves the
repeated unsaturated compounds and this type of
polymerization takes place by ionic (cation or anionic) as
well as free radical mechanism. Condensation reaction
between two monomers. Each monomer normally contains
two functional groups. Branch chain polymers may be
condensation or addition but cross-linked polymers are
always condensation polymers.
