Answer» SOLUTION :INTERMOLECULAR forces of attraction is a measure of the tensile STRENGTH of a polymer. Since elastomers have the weakest intermolecular forces of attraction followed by plastics while FIBRES have the strongest forces of attraction. In other words. intermolecular forces of attraction increase in the order : ELASTROMERS `lt` plastics `lt` fibres, i.e., (i) Neoprene `lt` Polythene `lt` Terylene (ii) Bnua `lt` Polystyrene `lt` Terylene |
