Buna-S is an elastomer.
Polymer chains are held together by the weakest intermolecular forces.
Weak binding forces permit the polymer to be stretched.
Terylene is a fibre:
Thread-forming solids which possess high tensile strength and high modulus
Characteristics can be attributed to strong intermolecular forces like hydrogen bonding
Strong forces lead to close packing of chains, and thus, impart crystalline nature
Hence, Terylene has stronger intermolecular forces of attraction as compared to Buna-S.

Answer:
generally when buna s and terylene are compared on the basis of intermolecular forces, it is found tht terylene has stronger intermolcular forces as because of the presence of H-bonding .
on the other hand buna s has weaker intermolecular bonding.
i hope it works...
