    摘要: Rubber compositions for automotive tire treads are made up of a selected class of base rubbers and a selected class of synthetic plasticizers in specified amounts. The plasticizer is derived from esterification of a diglycerin or an alkylene oxide adduct of a polyhydric alcohol with a selected class of higher fatty acids. Gripping performance is maintained for a prolonged period of time.
