Compositions for sports equipment
View Patent ↗Compositions comprising the reaction product of: (a) a polyalkenamer; and (b) an organic modifier that includes at least one carbon to carbon unsaturated bond and at least one functional group selected from carboxyl, hydroxyl, amino, epoxy, (meth)acrylate, vinyl, ester, isocyanate, carbonyl, urethane, anhydride, or a metal salt thereof. Also disclosed are golf balls that include (i) a core, (ii) at least one intermediate layer, and (iii) at least one cover layer, wherein at least one of the core, intermediate layer or cover layer includes the polylalkenamer/functionalized organic modifier composition as a majority ingredient.
1. A golf ball comprising:
(i) a core;
(ii) at least one intermediate layer; and
(iii) at least one cover layer,
wherein at least one of the core, or the at least one intermediate layer comprises a reaction product of:
(a) a polyalkenamer; and
(b) an organic modifier selected from a metal salt of a carboxyl-terminated polybutadiene, or a metal salt of a carboxyl-functionalized polyisoprene,
wherein the reaction product is a crosslinked ionomer.
2. The golf ball of claim 1 , wherein the reaction product is a majority ingredient in the respective core or intermediate layer.
3. The golf ball of claim 1 , wherein the metal salt includes a metal cation selected from Li + , Na + , K + , Zn 2+ , Ca 2+ , Co 2+ , Ni 2+ , Cu 2+ , Pb 2+ , Mg 2+ or a mixture thereof.
4. The golf ball of claim 1 , wherein the polyalkenamer is a polyoctenamer.
5. The golf ball of claim 1 , wherein the reaction product comprises from about 5 to about 70 wt % of polyalkenamer, based on the combined weight of components (a) and (b).
6. The golf ball of claim 1 , wherein the reaction product is present in the core or the at least one intermediate layer in an amount of at least 50 wt %, based on the total weight of the core or the at least one intermediate layer.
7. The golf ball of claim 1 , wherein the reaction product is present in the core or the at least one intermediate layer in an amount of at least 80 wt %, based on the total weight of the core or the at least one intermediate layer.
8. The golf ball of claim 1 , wherein the golf ball has three intermediate layers.
9. A golf ball comprising:
(i) a core;
(ii) at least one intermediate layer; and
(iii) at least one cover layer,
wherein at least one of the core or the at least one intermediate layer comprises a reaction product of:
(a) a polyalkenamer;
(b) an organic modifier selected from a metal salt of a carboxyl-terminated polybutadiene, or a metal salt of a carboxyl-functionalized polyisoprene;
(c) a crosslinking agent; and
(d) a co-crosslinking agent,
wherein the reaction product is a crosslinked ionomer.
10. The golf ball of claim 9 , wherein the polyalkenamer is a polyoctenamer.
11. The golf ball of claim 9 , wherein the crosslinking agent comprises zinc oxide, sulfur, sulfur compounds, organic peroxide, zinc peroxide, azo compounds, magnesium oxide, benzothiazole sulfenamide accelerator, benzothiazyl disulfide, phenolic curing resin, m-phenylene bis-maleimide, thiuram disulfide, dipentamethylene-thiuram hexasulfide, or a mixture thereof.
12. The golf ball of claim 9 , wherein the co-crosslinking agent comprises an unsaturated fatty acid having from about 3 to about 8 carbon atoms, or a metal salt thereof.
13. The golf ball of claim 9 , wherein the reaction product comprises from about 5 to about 70 wt % of polyalkenamer, based on the combined weight of components (a) and (b).
14. The golf ball of claim 9 , wherein the reaction product is present in the core or the at least one intermediate layer in an amount of at least 50 wt %, based on the total weight of the core or the at least one intermediate layer.
15. The golf ball of claim 9 , wherein the reaction product is present in the core or the at least one intermediate layer in an amount of at least 80 wt %, based on the total weight of the core or the at least one intermediate layer.
