| 发明名称 | Rubber composition for golf ball | ||
| 摘要 | Rubber composition for golf balls which includes: (A) a base rubber containing a polybutadiene having a cis-1,4 bond content of at least 60 wt %; (B) an unsaturated carboxylic acid and/or a metal salt thereof; (C) an anthranilic acid derivative of the general formula; wherein R1 and R2 are each independently a hydrogen atom or a hydrocarbon group of 1 to 20 carbons, m is an integer from 1 to 4, and n is an integer from 1 to 3, with the proviso that if m and/or n is 2 or more, each occurrence of R1 and R2 may be the same or different; and (D) an organic peroxide having a one-minute half-life temperature which is at least 158° C. and less than 175° C. The rubber composition for golf balls of the invention enables a high-quality molded and crosslinked product having a suitable hardness and a high resilience to be obtained. | ||
