Abstract
A golf ball comprising a core and a cover, wherein the core or the cover is formed from a composition comprising at least one acid functional polyurethane, polyurea, or copolymer thereof.
Claims28
A golf ball comprising a core and a cover, wherein at least one of the core or the cover is formed from a composition comprising at least one acid functional polyurethane, polyurea, or copolymer thereof.
A golf ball comprising a core and a cover, wherein at least one of the core or the cover comprises an acid functional polyurethane or polyurea prepolymer comprising an acid functional polyol or oligomer, and the prepolymer has a formula:
- 14
- where
- A=a straight chain or branched aliphatic or alicyclic group, a substituted straight chain or branched aliphatic or alicyclic group, or an aromatic or substituted aromatic group;
- B=R—Y;
- R=a straight chain or branched aliphatic or alicyclic group, a substituted straight chain or branched aliphatic or alicyclic group, or an aromatic or substituted aromatic group;
- and
- Y=HSO3, HCO2, or H2PO3.
A golf ball comprising a core and a cover, wherein at least one of the core or the cover comprises an acid functional polyurethane, polyurea, or copolymer thereof in an amount sufficient to increase the golf ball coefficient of restitution by at least about 5% compared to a polyurethane or polyurea without acid functional groups.
