Abstract
The present invention provides a solid golf ball which imparts a superior shot feeling to the golfer and exhibits stabilized repulsion performance when it is hit at any head speed. The solid golf ball of the present invention comprises a core containing at least one layer which is molded by vulcanizing the rubber composition including: (a) a base rubber, (b) a co-crosslinking agent, (c) an organic peroxide, and (d) a bromine-substituted thiophenol compound represented by the formula, or a monovalent or divalent metal salt thereof: (wherein at least one of R1 to R5 is Br).
Claims15
A solid golf ball comprising
- a core containing at least one layer, and
- a cover containing at least one layer and covering the core,
- wherein the at least one layer of the core is molded by vulcanizing a rubber composition including:

- (b) a co-crosslinking agent,
- (c) an organic peroxide, and
- (d) a bromine-substituted thiophenol compound represented by the following formula, or a monovalent or divalent metal salt thereof:
- wherein R1 to R5 represent Br or hydrogen, and at least three of R1 to R5 is Br.
A solid golf ball comprising
- a core containing at least one layer, and
- a cover containing at least one layer and covering the core,
- wherein the at least one layer of the core is molded by vulcanizing a rubber composition including:
- (a) 100 parts of a high cis-polybutadiene rubber,
- (b) 15 to 45 parts of a co-crosslinking agent,
- (c) 0.2 to 5 parts of an organic peroxide, and
- (d) 0.1 to 2 parts of a bromine-substituted thiophenol compound represented by the following formula, or a monovalent or divalent metal salt thereof based on mass:
- wherein R1 to R5 represent Br or hydrogen, and at least three of R1 to R5 is Br.
