  • Multi-layer core golf ball having thermoset rubber cover
    Patent number: 8298099
    Abstract: A golf ball with one or more thermosetting rubber core layers, intermediate layers and cover layers. At least one of the ball's layers has a moisture vapor barrier property, and the thermosetting rubber layers follow a cis- or a trans-polybutadiene gradient from the center of the ball to its cover. Each of the core layer, intermediate layer and cover layer comprises a cross-linked thermoset rubber composition having a primary rubber component of polybutadiene having a polydispersity of no greater than about 2 or a weight average molecular weight Mw greater than about 400,000 in an amount of greater than about 80% by weight and a crosslinking initiator.
    Type: Grant
