Compositions for use in golf balls
View Patent ↗A golf ball comprising a core, an outer cover layer, and, optionally, an intermediate layer disposed between the core and the outer cover layer is presently disclosed. At least one layer of the golf ball is formed from a composition comprising a base polymer, a crosslink initiator, and at least one additive having a structure of: where at least one of R 1 to R 5 is selected from perhaloalkyls, (per)haloaryls, (per)haloaralkyls, (per)haloalkaryls, and (per)halocycloalkyls; the remainder of R 1 to R 5 are the same or different organic substituents or hydrogen; n is an integer of 1 or greater; and Z is selected from metal cations, organometallic cations, and non-metal cations, and, when n is 1, Z may also be selected from hydrogen and halogens; or a structure of: where at least one of R 1 to R 5 and at least one of R 6 to R 10 is selected from perhaloalkyls, (per)haloaryls, (per)haloaralkyls, (per)haloalkaryls, and (per)halocycloalkyls; the remainder of R 1 to R 10 are the same or different organic substituents or hydrogen; and n is an integer of 1 or greater. The outer cover layer may comprise a polyurethane or polyurea composition. At least one portion of the golf ball comprises a composition that enhances physical properties and/or performance characteristics (e.g., coefficient of restitution) of the golf ball. Preferably, the coefficient of restitution of the core is 0.8 or greater.
1. A golf ball comprising a core and at least one layer disposed about the core, wherein the core or the layer is formed from a composition comprising a base polymer, a crosslink initiator, and at least one additive having a structure of
where at least one of R 1 to R 5 is a perhaloalkyl, (per)halocycloalkyl, or (per)haloaryl substituent; the remainder of R 1 to R 5 are the same or different organic substituents or hydrogen; Z is a non-metal cation selected from the group consisting of quaternary ammonium, quatenary pyridinium, quaternary quinolinium, (organo)phosphonium, (organo)sulfonium, (organo)oxonium, (organo)iodonium, and (organo)azonium; and n is an integer of 1 or greater.
2. The golf ball of claim 1 , wherein at least one of R 1 , R 3 , and R 5 is a perhaloalkyl substituent having 1 to 6 carbon atoms.
3. The golf ball of claim 2 , wherein the perhaloalkyl substituent is selected from the group consisting of trichloromethyl, tribromomethyl, and triiodomethyl.
4. A golf ball comprising a core and at least one layer disposed about the core, wherein the core or the layer is formed from a composition comprising a base polymer, a crosslink initiator, and at least one additive having a structure of

where at least one of R 1 to R 5 is a (per)haloaryl; at least one of R 6 to R 10 is selected from perhaloalkyls, (per)haloaryls, (per)haloaralkyls, (per)haloalkaryls, and (per)halocycloalkyls; the remainder of R 1 to R 10 are the same or different organic substituents or hydrogen; and n is an integer of 1 or greater.
