Which are the different types polymers based on molecular forces?

based on the inter molecular forces polymers can mainly classified in to 4 a)Elastomers :-the polymers that have elasticity, like rubber are referred to as elastomers.the polymer chain in elastomers are held together by the weakest intermolecular forces.they have ability to be elongated under stress and regain their former shapes when the stress is removed b)Fibers:-these are thread like polymers which can be woven into fabric.they have high tensile strength and high modulus.this is due to strong inter molecular forces like hydrogen bond. eg:- cotton,wool,silk,nylon and Dacron etc c)Thermoplastic:-The inter molecular forces of attraction in the thermoplastics polymers are intermediate between those of elastomers and fibres .As a result thermoplastic polymers when heated became melt and can be molded again in different forms. eg:- polyethylene polypropylene and polystyrene d)Thermosetting plastic:- These polymers are prepared from low molecular mass semifluid polymers .thy cannot be reshaped on heating because the polymer chain under go extensive cross linking resulting in the formation of three dimensional network of inter connected polymer chain read less
