Benefits of technology

[0016] The present invention satisfies the noted general objectives and provides, in one aspect, a polybutadiene rubber composition for producing a golf ball or a molded component thereo

Problems solved by technology

For example, a thread wound ball is relatively difficult to manufacture due to the number of production steps required and the careful control which must be exercised in each stage of manufacture to achieve suitable roundness, velocity, rebound, “click”, “feel”, and the like.
Additionally, a soft thread wound (three-piece) ball is not well suited for use by the less skilled and/or high handicap golfer who cannot intentionally control the spin of

Abstract

An elastomeric composition for forming a golf ball or a component thereof is disclosed that includes the use of a metal thiosulfate, either alone or in combination with one or more halogenated organic sulfur compounds, such as halogenated thiophenol (HTP), or salts thereof. The composition produces a molded product exhibiting an enhanced combination of increased compression (i.e., softness) and/or resilience (C.O.R.).

Description

FIELD OF THE INVENTION [0001] The present invention relates to the field of golf ball construction and, more particularly, to elastomeric compositions for producing golf balls or molded components thereof. The improved golf balls exhibit enhanced combinations of compression and / or resilience properties. Methods of preparing such golf balls are also disclosed herein. BACKGROUND OF THE INVENTION [0002] Golf balls have traditionally been categorized in three different groups. These are, namely, one-piece or unitary balls, wound balls, and multi-piece solid balls. [0003] A one-piece ball typically is formed from a solid mass of moldable material which has been cured to develop the necessary degree of hardness. The one-piece ball generally possesses no significant difference in composition between the interior and exterior of the ball. These balls do not have an enclosing cover. One piece balls are described, for example, in U.S. Pat. No. 3,313,545; U.S. Pat. No. 3,373,123; and U.S. Pat....
