Golf ball core
A golf ball with a center core comprising 1,4 polybutadiene with a cis content more than 50% and containing a metal salt of acrylate, wherein the 1,4 polybutadiene has 5 to 60 weight percent of a metal salt of acrylate, is disclosed herein. The metal salt of acrylate is preferably selected from zinc, magnesium, sodium, and calcium.
1. A golf ball comprising:
a core formed from a mixture comprising 1,4 polybutadiene with a cis content more than 50% and containing a metal salt of acrylate, wherein the 1,4 polybutadiene has 5 to 60 weight percent of a metal salt of acrylate chemically attached to a main chain of the 1, 4 polybutadiene, 0.4 to 2.5 weight percent graphene material, 1-30 weight percent polyisoprene, 10-50 weight percent zinc diacrylate, 1-30 weight percent zinc oxide, 1-20 weight percent zinc stearate, and 0.1-10 weight percent peroxide initiator;
an inner mantle disposed over the core;
an outer mantle disposed over the inner mantle;
a cover layer disposed over the outer mantle.
2. The golf ball according to claim 1 wherein metal salt of acrylate are zinc, magnesium, sodium, and calcium.
3. The golf ball according to claim 1 wherein the cover layer has a thickness ranging from 0.025 inch to 0.045 inch.
4. The golf ball according to claim 1 wherein the cover layer is formed of a TPU.
