ABSTRACT:
A thermoplastic elastomer composition is provided which is highly durable and free from oxidative deterioration when exposed to elevated temperature as in molding and also ambient temperature at which an end product thereof is used. These advantageous features are attributable to the use of a hydrogenated oil of the class disclosed which serves effectively to suppress the tendency of an elastomer undergoing gelation or cross-linking particularly when heated in the atmosphere. The hydrogenated oil is derivable from hydrogenation of a liquid product resulting from thermally treating a coal tar or distillates thereof at above 400.degree. C.; a liquid product resulting from thermally treating at above 400.degree. C. a petroleum crude oil, distillates thereof, or a liquid hydrocarbon derived from catalytic cracking, hydrogenative cracking or catalytic reforming of petroleum distillates; or a thermally cracked tar resulting from thermally cracking a petroleum crude oil or distillates thereof.
