Abstract
A method of making a golf ball core comprising the steps of providing a first polybutadiene pre-impregnated with at least about 50 weight percent of a first filler; providing a second polybutadiene substantially free of the first filler; providing a free radical initiator and a crosslinking agent; mixing the second polybutadiene, the free radical initiator, and the crosslinking agent with the first polybutadiene to form a polybutadiene blend; and molding the polybutadiene blend into the golf ball core.

A method of making a golf ball core comprising the steps of:
- providing a first polybutadiene pre-impregnated with at least about 50 weight percent of tungsten;
- providing a second polybutadiene substantially free of tungsten;
- mixing the second polybutadiene with the first polybutadiene to form a polybutadiene blend;
- mixing a crosslinking agent, and a free radical initiator into the polybutadiene blend to form a reaction mixture;
- placing the reaction mixture into a mold cavity;
- heating and pressurizing the reaction mixture to form the golf ball core.

- mixing a second polybutadiene, substantially free of the first filler, into the first polybutadiene to form a polybutadiene blend;
- mixing a cis-to-trans catalyst, a crosslinking agent, and a free radical initiator into the polybutadiene blend to form a reaction product;
- molding the reaction product into a golf ball core;
- and
- forming a cover layer about the core to produce the golf ball.
