Claims32
A golf ball comprising a core and a cover, wherein the core comprises an elastomeric polymer, a free radical initiator, a salt of unsaturated carboxylic acid having about 3 to about 8 carbon atoms, and at least one stable free radical comprising hydrazyl radicals, allyloxyl radicals, trityl radicals, galvinoxyl radicals, or derivatives thereof having at least one substituent group comprising amino, isocyanate, hydroxyl, carboxyl, oxirane, or thiirane.
The golf ball claim of 20, wherein the free radical scavangers comprise one or more compounds selected from the group consisting of benzoquinones;
- hydroquinones;
- phenols;
- benzaldehydes;
- and cyclohexadiene-1-ones.
A golf ball comprising a core and a cover, wherein the cover is formed of a composition comprising a salt of a stable free radical and at least one thermoplastic or thermosetting material.
