Abstract
Official abstract text for this publication.
Disclosed herein are heterogeneous golf ball compositions comprising a thermoplastic matrix and discrete particles of crosslinked polymer dispersed within the matrix.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf ball comprising an innermost layer formed from a heterogeneous composition comprising: a thermoplastic matrix formed from a composition comprising greater than 50 wt %, based on the total weight of the matrix composition, of a non-ionomeric base resin selected from one or more E/X/Y-type acid copolymers of ethylene, an α,β-unsaturated carboxylic acid, and optionally a softening comonomer, and discrete particles of crosslinked polymer dispersed within the matrix, wherein the discrete particles of crosslinked polymer have a particle size of from 0.074 mm to 2.38 mm and are present in the composition in an amount of from 30 wt % to 40 wt %, based on the total weight of the composition, and wherein the crosslinked polymer is selected from the group consisting of polybutadiene, polyisoprene, ethylene propylene rubber, styrene-butadiene rubber, styrenic block copolymer rubbers, butyl rubber, halobutyl rubber, polystyrene elastomers, polyethylene elastomers, polyurethane elastomers, polyurea elastomers, copolymers of isobutylene and para-alkylstyrene, halogenated copolymers of isobutylene and para-alkylstyrene, acrylonitrile butadiene rubber, polychloroprene, alkyl acrylate rubber, chlorinated isoprene rubber, acrylonitrile chlorinated isoprene rubber, polyalkenamer, and combinations of two or more thereof. 2. The golf ball of claim 1 , wherein the matrix composition comprises 70 wt % or greater of the non-ionomeric base resin. 3. The golf ball of claim 1 , wherein the matrix composition comprises 80 wt % or greater of the non-ionomeric base resin. 4. The golf ball of claim 1 , wherein the discrete particles of crosslinked polymer are present in the composition in an amount of from 35 wt % to 40 wt %, based on the total weight of the composition.
