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.
