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, or a combination thereof for a time sufficient to polymerize said 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.

20. A method of forming a portion of a golf ball comprising the steps of:
-
providing a first polymeric component comprising at least one monomer, oligomer, prepolymer, or a combination thereof;
sufficiently polymerizing the first polymer component to form a first polymer or first polymer network;
providing a second polymeric component comprising at least one monomer, oligomer, prepolymer, or a combination thereof;
sufficiently polymerizing the second polymer component to form a second polymer or second polymer; and
crosslinking the first polymer or first polymer network with the second polymer or second polymer network to form an IPN, wherein the first polymeric component is polymerized by exposing the first polymeric component to a first energy source, a first initiator, or a combination thereof for a time sufficient to polymerize the first polymeric component and the second polymeric component is polymerized by exposing the second polymeric component to a second energy source, a second initiator, or a combination thereof for a time sufficient to polymerize the second polymeric component.
