Thermoplastic elastomer composition, process for producing the same and golf ball using the same for cover

摘要

Disclosed is a thermoplastic elastomer composition having characteristics of both thermoplastic resin and rubber, and a golf ball using the thermoplastic elastomer composition as the cover. The thermoplastic elastomer composition of the present invention comprises a thermoplastic resin and crosslinked diene rubber particles having an average diameter of not more than 10 mu m dispersed in the thermoplastic resin, which is prepared by dynamic crosslinking diene rubber dispersed in the thermoplastic resin with crosslinking agent.
