Solution

Linear polymers:
These polymers consist of long and straight chains
Condensation polymers:
Condensation polymers are formed by repeated condensation between two different bi-functional or tri-functional monomeric units. In these polymerisation reactions, the elimination of small molecules such as water, alcohol, hydrogen chloride, etc. takes place.
Natural polymers:
These polymers are found naturally in plants and animals.
Copolymerization is a polymerisation reaction in which a mixture of more than one monomeric species is allowed to polymerise and form a copolymer.
A. Teflon is a linear polymer
B. Natural rubber is a natural polymer and it contains long chains (linear polymer).
C. Terelyne (dacron) is a condensation polymer as elimination of methanol (small molecule) takes place. It is a co-polymer prepared from 2 molecules.
D. Proteins are natural, linear and co-polymers.
