The present invention is related to a core-shell particle and preparation and use thereof. The core of the core-shell particle includes a vinyl polymer. The shell of the core-shell particle includes a hydrophobic silane bonded to a surface of the core via a silane coupling agent. The core-shell particles are applied in a matting material as a matting agent.

The present invention relates to the use of a mono (meth)acrylate ester in a golf ball layer. The mono (meth)acrylate ester may be added to one or more portions of a golf ball including a core, intermediate, or cover layer. For example, in one embodiment, the mono (meth)acrylate ester may be blended with a polybutadiene rubber material. In another embodiment, the mono (meth)acrylate ester of the present invention may be blended with an ionomer. In some embodiments, the mono (meth)acrylate ester may be blended with a formulation including both a polybutadiene rubber component and an ionomer.
