PRODUCTION OF REINFORCED RUBBER COMPOSITION

摘要

A process for producing a reinforced rubber composition comprising the steps of: dispersing fine fibers of thermoplastic polymer having groups in a continuous phase comprising vulcanizable synthetic rubber, other than butadiene rubber, containing a tackifier incorporated thereinto; and grafting the vulcanizable synthetic rubber onto the thermoplastic polymer at the interface of the fine fibers through a novolak type phenol resin. This reinforced rubber composition is capable of providing a vulcanizate having an excellent strength and modulus.
