How are polymers classified categorieson thebasis of intermolecularforces ?

Answer»

Solution :There are fourtypes of POLYMERS on the basis of intermolecular forces :
(i)Thermoplastic : They becomessofton HEATING, Theydoe not have cross linkage . Polytheneand polypropene are exampleof ths type of polymers(ii) Themosetting polymers : Theyhavestrongintermolecularforce of ATTRACTION . Bakeliteand melamine - formadehyded resin are examples of thiscategory.
(iii)ELASTOMERS: Theyhave weak intermolecular forces of attraction . for example , Naturalrubberand Neoprene .
(iv) Fibres : They are thread - likematerials WHICHARE crystallinein nature . They have strongNylon , 6,6 belong to fibres.
