Golf balls containing interpenetrating polymer networks
First Claim
Patent Images
1. A method of forming a portion of a golf ball comprising the steps of:
- providing at least a first polymeric component and a second polymeric component, each polymeric component comprising at least one monomer, oligomer, prepolymer, or a combination thereof;
sufficiently polymerizing each polymeric component sequentially or simultaneously to form a polymer or polymer network;
crosslinking each polymer or polymer network to the other polymer or polymer network to form an interpenetrating polymer network (“
IPN”
); and
forming the IPN into the portion of the golf ball,wherein each polymeric component of the mixture is polymerized by exposing the mixture to at least one energy source, at least one initiator present in an amount from about 0.1 to about 10 parts per hundred of total polymer component, or a combination thereof for a time sufficient to polymerize the polymeric component.

Abstract
The present invention is directed to a method of forming a golf ball that contains an interpenetrating polymer network, or IPN, which includes at least two polymeric components, in one or more of the layers. In one preferred embodiment, the present invention is directed to a method of forming an intermediate or cover layer that contains an IPN.

17. A method of forming a golf ball having a center, a cover, and an intermediate layer disposed between the center and the cover comprising the steps of:
-
providing at least a first polymeric component and a second polymeric component, each polymeric component comprising at least one monomer, oligomer, prepolymer, or a combination thereof; sufficiently polymerizing each polymeric component sequentially or simultaneously to form a polymer or polymer network; crosslinking each polymer or polymer network to the other polymer or polymer network to form an interpenetrating polymer network (“
IPN”
); andforming an intermediate layer from the IPN, wherein each polymeric component of the mixture is polymerized by exposing the mixture to at least one energy source, at least one initiator, or a combination thereof for a time sufficient to polymerize the polymeric component. - View Dependent Claims (18, 19)
