Compositions comprising an amino triazine and ionomer or ionomer precursor
View Patent ↗Disclosed embodiments concern using at least one triazine, typically an amine or polyamine triazine (referred to as amino triazines), in combination with at least one ionomer or ionomer precursor to form compositions useful for making sporting equipment, such as golf ball components. The ionomer or ionomer precursor typically includes plural acid functional groups, such as carboxyl or carboxylate groups, that react or form salts with the amino triazine. Specific examples, without limitation, of suitable amino triazines include guanamine, 6-methyl-1,3,5-triazine-2,4-diamine(acetoguanamine), 6-nonyl-1,3,5-triazine-2,4-diamine(nonylguanamine), 6-phenyl-1,3,5-triazine-2,4-diamine(benzoguanamine) and 2,4,6-triamino-triazine(melamine).
1. A method for making a golf ball, comprising:
providing a composition comprising a fully neutralized, partially neutralized or non-neutralized ionomer polymer and an effective amount of an amino triazine that reacts with the ionomer polymer where, prior to any reaction with the ionomer polymer or an ionomer polymer precursor, the amino triazine has a formula
and where, subsequent to reaction with the ionomer polymer or ionomer polymer precursor, the ionomer polymer has a formula
and/or a crosslinked ionomer polymer compound having a formula
where R 1 -R 5 are independently aliphatic, substituted aliphatic, alkoxy, amine, aryl, substituted aryl, heteroaryl, substituted heteroaryl, halogen or hydrogen; and
forming at least one layer of a golf ball comprising the composition.
2. The method according to claim 1 where the amino triazine is guanamine, 6-methyl-1,3,5-triazine-2,4-diamine (acetoguanamine), 6-nonyl-1,3,5-triazine-2,4-diamine (nonylguanamine), 6-phenyl-1,3,5-triazine-2,4-diamine (benzoguanamine), or 2,4,6-triamino-triazine (melamine).
3. The method according to claim 1 where the ionomer polymer or ionomer polymer precursor has plural reactive functional groups selected from an oxo acid of carbon, an oxo acid of sulfur, an oxo acid of phosphorous, or combinations thereof, and from about 5% to about 100% of the reactive functional groups react with the amino triazine compound.
4. The method according to claim 1 wherein the composition further comprises at least one filler, at least one nanofiller, or a mixture thereof.
5. The method according to claim 1 where the golf ball is a three-piece golf ball comprising a rubber-based core, at least one intermediate layer and an outer cover layer, at least one of the intermediate layer and outer cover layer comprising the partially neutralized or non-neutralized ionomer polymer.
6. The method according to claim 1 where the golf ball is a four-piece golf ball having a rubber-based core having a center, an inner intermediate layer, an outer intermediate layer, and a cover, at least one of the inner layer, outer intermediate layer or cover comprising the partially neutralized or non-neutralized ionomer polymer.
7. The method according to claim 1 where the golf ball comprises a core, an inner mantle layer, an intermediate mantle layer, an outer mantle layer, and at least one cover layer, and where at least the core or one of such layers comprises the partially neutralized or non-neutralized ionomer polymer.
8. The method according to claim 1 where the ionomer polymer or ionomer polymer precursor is partially or fully neutralized by an acetate, oxide or hydroxide metal salt.
9. The method according to claim 1 where the ionomer polymer or ionomer polymer precursor has plural reactive functional groups, and from about 5% to about 100% of the reactive functional groups react with the amino triazine compound.
