Rubber composition comprising a thermoplastic filler and compatibilizer

摘要

A rubber composition, which can be used for manufacturing tires, is based on one or more diene elastomers, on one or more reinforcing fillers, and on a crosslinking system. The rubber composition includes particles of one or more thermoplastic materials chosen from thermoplastic materials with melting or softening points varying from 80° C. to 300° C. The rubber composition also includes one or more compatibilizing agents chosen from block copolymers that includes at least one diene elastomer block and at least one thermoplastic block compatible with the one or more thermoplastic materials.

1. A rubber composition for manufacturing tires, the rubber composition comprising:
one or more diene elastomers; one or more reinforcing fillers; a crosslinking system; polystyrene particles, where the particles exhibit a volume-average diameter of less than or equal to 200 μm; and one or more compatibilizing agents chosen from block copolymers that include at least one diene elastomer block and at least one thermoplastic block compatible with the polystyrene particles,
wherein the one or more compatibilizing agents is selected from the group consisting of styrene/butadiene diblock copolymers, styrene/isoprene diblock copolymers, styrene/butadiene/styrene triblock copolymers, styrene/isoprene/styrene triblock copolymers, and blends thereof.
