    Abstract: Methods for making multi-layered golf balls having at least one layer or coating made from a thiol-ene composition and the resultant golf balls are provided. A polymerizable composition comprising multifunctional thiol and -ene compounds is used to form the layer or coating. In one embodiment, the outer cover layer is made from the thiol-ene material. In another embodiment, a thiol-ene composition is applied as a protective coating over the outer cover layer. The thiol-ene layer or coating helps provide the ball with good impact durability and, toughness.

    Abstract: The present invention provides golf balls having a rubber core, and a cover layer made from a thermoset polyurethane of polyurethane-urea that is the reaction product of a polyisocyanate with moisture-resistant polyol and curing agent. An intermediate layer, formed from an olefin-based acid copolymer ionomer composition and preferably an ethylene acid copolymer, is disposed between the rubber core and cover. The moisture-resistant polyol is preferably a reaction product of dimer acid or dimer ester and a polyolefin diol, or a polybutadiene polyol, or a polyisoprene. Preferably, the cover layer has a moisture vapor transmission rate (MVTR) between 3 grams·mm/m2·day to 4 grams·mm/m2·day.

    Abstract: Compositions for golf balls that include polyurethane and polyurea linkages and that are crosslinked in the soft segments of the polymer backbone. In particular, the compositions of the invention, which are based on a polyurethane and/or polyurea prepolymers, have improved crosslink density from the crosslinking between the soft, unsaturated segments of the polymer backbone. The curative blend includes at least one isocyanate-reactive component and a free radical initiator.
