Arrange the following polymers in increasing order of their intermolecular forces. Nylon-6, 6, buna-S, polythene, neoprene

The increasing order of intermolecular forces in different polymers is elastomers < plastics $ \lt $ fibres. So, in order to solve such problem, first classify the given polymer into the above classes and then arrange them in increasing order of forces. Neoprene (synthetic rubber) is an elastomer, buna-S is also an elastomer, polythene is plastic and nylon-6, 6 is a fibre. So, the increasing order of intermolecular forces of the given polymer is Neoprene $ \lt $ buna-S $ \lt $ polythene $ \lt $ nylon- 6,6
