Which of the following polymer has strongest intermolecular forces of attraction?

Neoprene have the weakest intermolecular forces as it is a elastomer. There are only few cross-links between the chains. Terylene have strong intermolecular forces like dipole-dipole interaction. It is a fibre type of polymer. Polyster and polythene are thermoplastic types of polymer. They have intermolecular forces, which are intermediate between those of elastomers and fibres.
