1. A golf ball comprising a core, a cover and an intermediate layer disposed between the core and cover;
- wherein the cover is formed from a mixture comprising a thermoplastic polymer and a polymethyl (meth)acrylate-based copolymer; and
wherein the polymethyl (meth)acrylate-based copolymer is included in the mixture in an amount of from 15 wt % to 50 wt % of the total weight of the mixture.

Abstract
Golf ball incorporating mixtures of thermoplastic polymers and polymethyl methacrylate (MMA) copolymers. The thermoplastic polymer and MMA copolymers may be included in weight ratios of from 98:2 to 50:50. The mixture may have different hardness than that of the thermoplastic polymer, a glass transition temperature Tg-m greater than a glass transition temperature Tg-tp of the thermoplastic polymer, and a modulus, tensile strength and ultimate elongation greater than that of the thermoplastic polymer.
