ABSTRACT:
Ionomeric reaction products are disclosed that are made by combining a monomer, oligomer or polymer having at least one reactive carboxyl group and/or isocyanate group, or functional group or groups equivalent thereto or derived therefrom, with an amine compound having both an amine and an anionic functional group and a formulain-line-formulae description="In-line Formulae" end="lead"?[RHN—(R1)m—(X−)n]o-Ma+pin-line-formulae description="In-line Formulae" end="tail"?where R is hydrogen, aliphatic, alicyclic, arylaliphatic or aromatic, R1is a linking group that links the amine and salt functional groups and is aliphatic, alicyclic, arylaliphatic or aromatic, X is an anionic group, M is a positively charged species, a is 1-4, m is 0 or greater, n is 1-4, o is 1-4 and p is 0-4, more typically 1-4. An amount of the amine compound is used to react with at least a portion of the reactive functional groups. A method for making a golf ball also is disclosed, as are golf balls comprising disclosed ionomers. At least one component of a golf ball, such as a cover layer, is made comprising disclosed ionomers. The golf ball can have any construction suitable for a golf ball, including multi-layered balls, such as a 3- or 4-piece ball.
