Differentiate between rubbers and plastics on the basis of intermolecular forces.

Text Solution

Verified by Experts

Rubber is a natural polymer which possess elastic properties. It is a linear polymer of isoprene (2-methyl-1,3-butadiene).
In natural rubber, cis-polyisoprene molecules consists of various chains held together by weak van der Waals. interaction and has coiling structure.
So it can be stretched like a spring and it regain its original shape after force is released.

Plastics are synthetic or semi-synthetic polymers of organic compounds which possess intermediate intermolecular forces of attraction. It has linear, structure that can be moulded but cannot regain its original shape after stretching is over.
