GOLF BALLS HAVING DUAL CORES MADE OF POLYBUTADIENE RUBBER / IONOMER BLENDS

摘要

A multi-piece golf ball comprising at least one component made of a polybutadiene rubber/ionomer resin blend is provided. The ball preferably contains a dual-core comprising an inner core and surrounding outer core layer. Preferably, the polybutadiene rubber/ionomer resin blend is used to form the outer core layer. The center hardness of the inner core is preferably greater than the outer surface hardness of the outer cover layer. The resulting ball has high resiliency and good impact durability.
