Polybutadiene rubber / ionomer blends for golf balls having dual cores and covers |
| 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 a center and surrounding outer core layer. The polybutadiene rubber/ionomer resin blend is used preferably to form the outer core layer. The ball further includes a cover comprising inner and outer cover layers. The surface hardness of the outer core layer is preferably greater than the material hardness of the inner cover layer. The resulting ball has high resiliency and good impact durability. |

1. A multi-piece of ball, comprising:
a dual-core comprising an inner core and outer core layer, the inner core having an outer surface and geometric center and the outer core layer having an outer surface and inner surface; the outer core being formed from a first rubber composition comprising polybutadiene rubber and ionomer resin, and a cover comprising an inner cover layer and outer cover layer, the cover being disposed about the outer core layer, wherein the outer core layer has an outer surface hardness greater than the material hardness of the outer and inner cover layers. |
