Abstract
A golf ball comprising a layer made from a liquid rubber composition is disclosed. A castable liquid polybutadiene is the preferred principal rubber component. The molecular weight of the castable liquid polybutadiene is at least about 1,000 and the castable liquid polybutadiene is in a liquid state at room temperature. The castable liquid rubber layer can be a cover layer, a casing layer, an intermediate layer or a core layer.
Claims8
A method of making a golf ball, said method comprising:
- providing a solid golf ball core having a diameter of from 1.55 inches to 1.60 inches;
- providing a rubber composition comprising castable liquid polybutadiene as the principal rubber component, an unsaturated vinyl co-agent, a cross-linking agent comprising one or more metallic salts of unsaturated fatty acids or monocarboxylic acids, and a free radical initiator;
- wherein the molecular weight of the castable liquid polybutadiene is at least 1,000 and wherein the castable liquid polybutadiene is in a liquid state at room temperature;
- and
- casting the rubber composition on the golf ball core to produce a cast layer having a thickness of from 0.01 inch to 0.05 inch.
