Abstract
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.
