BLEND OF BLOCK COPOLYMER, ONE OF WHICH IS EPOXIDIZED

摘要

Block copolymer compositions are provided comprising hydrocarbon block polymer containing at least two monoalkenyl arene blocks and at least one conjugated diene block or hydrogenated derivatives of said polymers, combined with a second block copolymer comprising at least one monoalkenyl polymer block and at least one epoxidized conjugated diene polymer block and hydrogenated derivatives thereof. These compositions are especially useful for such purposes as adhesion to polar surfaces, improvement in weatherability and high tensile strength.
