Abstract
This invention relates to methods of using cationic ionomers in golf ball cover compositions. Further, this invention relates to golf balls which have covers and cores and which incorporate urethane ionomers. The polyurethane golf ball cover has improved resiliency and initial velocity through the addition of an alkylating agent such as t-butyl chloride to introduce ionic interactions in the polyurethane and thereby produce cationic type ionomers.
Claims16
A golf ball having a cover and a core wherein the cover comprises a cationic polymer having cation groups on the polymer.
A golf bail having a cover and a core wherein the cover comprises a thermoplastic cationic polyurethane ionomer.
A golf ball having a cover and a core wherein the cover comprises a thermoset cationic polyurethane ionomer.
A method for making a golf bail comprising a cover and a core comprising the steps of:
- (a) providing a core;
- (b) covering said core with a material which comprises a cationic polymer having cation groups on the polymer.
