Dear stydent,,Different types ofpolymers have different intermolecular forces of attraction.Elastomers or rubbers have the weakest while fibres have thestrongest intermolecular forces of attraction. Plastics haveintermediate intermolecular forces of attraction. Hence, theincreasing order of the intermolecular forces of the given polymersis as follows: Buna−N< polyvinylchloride < Nylon 8
