ABSTRACT:
The present invention relates to improved cover compositions for golf ball construction. In this regard, it has been found that if high levels (i.e. greater than 10 pph resin) of metal stearates (i.e. zinc stearate, barium stearate, calcium stearate, magnesium stearate, etc.) are added to various ionomer resin formulations utilized in golf ball cover construction, the covers produced thereby exhibit similar or improved coefficient of restitution (C.O.R.) values combined with similar or reduced hardness (i.e. an increase in softness) properties. Moreover, since the metal stearates are significantly cheaper than the ionomer resins and the discovery that the metal stearates can be added at relatively high levels without detracting, and many instances enhancing the physical properties of the overall formulations, the addition of high levels of the metal stearates presents significant cost savings in the production of golf balls.
