Abstract
The composition disclosed herein involves an oil-extended composition comprising 10-200 parts of oil, preferably 25-125 parts, per 100 parts of a hydrogenated diblock copolymer comprising one block of polybutadiene and one block of a random copolymer of a vinyl arene, such as styrene, and butadiene. This hydrogenated diblock copolymer has improved properties as compared to corresponding hydrogenated random copolymers of the vinyl arene and butadiene, particularly with respect to high temperature properties, oil acceptance and stability against aging.
