USE OF CURABLE COMPOSITIONS CONTAINING DITHIANE MONOMERS FOR GOLF BALL CORES

摘要

The present invention is directed to a golf ball and, more particularly, a golf ball core having a curable core composition comprising a dithiane compound, a rubber based compound comprising cis-1,4-polybutadiene rubber, a crosslinking agent comprising a metallic salt of unsaturated carboxylic acid in an amount between 10 to 50 parts per hundred of rubber (pphr), a peroxide initiator, one or more filler materials, and optionally an organ sulfur compound, are used to provide soft and resilient cores.

1. A golf ball, comprising:
a core and a cover, the core comprising: a rubber based compound comprising cis-1,4-polybutadiene rubber; a crosslinking agent comprising a metallic salt of unsaturated carboxylic acid in an amount between 10 to 50 parts per hundred of rubber; a peroxide initiator; and a dithiane compound represented by the following chemical formula wherein X and X′ are each independently an —O— or —NR1—, where R1 is an H or a C1-C4 alkyl group; each R5 is independently an H, or a C1-C4 alkyl group, R4 is an organic radical having a valence of x+y, n is 3 to 6, m is 1 to 3, o is 1 to 3, x and y are at least 1, one or more methylene groups on the dithiane ring may be substituted with C1-C4 alkyl group, and adjacent alkyl groups may be joined with the carbon atoms to which they are attached to form a carbocyclic ring.
