Abstract
A silane is included in a homogeneous golf ball composition which is based on a cross-linked rubber polymer. The silane increases velocity of the golf ball when struck by a club. Such silanes have the formula R--Si(OR')(OR") (OR'") wherein each R is organic. Usually R', R" and R'" will be hydrocarbon and R will usually contain a functional group such as mercapto, amino, acrylic, epoxy and/or ether group.
Claims3
A homogeneous golf ball comprising a crosslinked rubber polymer in which the rubber polymer is at least about 60% cis-polybutadiene and is crosslinked with 5 to 50 phr of a crosslinking monomer having at least two acrylic groups, from about 1 to about 50 parts by weight solid particulate filler based on rubber polymer and from about 1% to about 10% by weight of a silane having the formulation R--Si(OCH.sub.3).sub.3 wherein R is selected from the class consisting of HS(CH.sub.2).sub.3, NH.sub.2 (CH.sub.2).sub.3, CH.sub.2 =C(CH.sub.3) COO(CH.sub.2).sub.3, and ##EQU1##
A molded solid golf ball comprising a spherical unitary body made by vulcanization of the composition consisting essentially of the following ingredients in the weight ratios stated:
- about 100 parts of a high cis content polybutadiene
- about 5 to 50 parts of a polyfunctional, ester type, crosslinking monomer
- about 0.5 to 10 parts of a peroxide curing agent
- about 25 parts of particulate filler material and
- about 0.1 to 20 parts of silane wherein said silane has a formula R--Si(OR')(OR")(OR'") wherein R', R" and R'" are alkyl and R is selected from the class consisting of mercapto alkyl, amino alkyl, acrylic and epoxyether alkyl.
