20080214735 | Interpenetrating polymer networks using blocked polyurethane/polyurea prepolymers for golf ball layers - 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 systems, in one or more of the layers. The first polymeric system may include a polyurethane-based or polyurea-based system having blocked isocyanate groups and the second polymeric system may include an epoxy-based or acrylic-based system, wherein the two systems are polymerized or cured simultaneously or sequentially to form an IPN. | 09-04-2008 |
20090011854 | REACTION INJECTION MOLDABLE COMPOSITIONS, METHODS FOR MAKING SAME, AND RESULTANT GOLF ARTICLES - The invention relates to a method for forming golf equipment, or a portion thereof, preferably for forming one or more layers of a golf ball, including: providing a first reactable component containing an isocyanate-containing compound, and a second reactable component containing at least one polyol, polyamine, or epoxy-containing compound; mixing the reactable components together to form a reactive mixture; and injecting the reactive mixture into a cavity or mold having a desired shape within a time sufficient to avoid substantial polymerization, gelation, or solidification. Alternately, instead of providing an isocyanate-containing reactable component and at least one polyol, polyamine, or epoxy-containing compound, the method may include providing at least two sets of precursor components that can be reacted to form at least two different polymers of an interpenetrating polymer network, at least one polymer being crosslinked, wherein, if any of the at least two component sets include a mixture of precursor components, then that mixture must be sufficiently non-reactive such that the sets of precursor components, when placed in contact with each other, can still form an interpenetrating polymer network. | 01-08-2009 |
20090011861 | GOLF BALLS CONTAINING INTERPENETRATING POLYMER NETWORKS - The present invention is directed to a golf ball that contains an interpenetrating polymer network, or IPN, including at least two polymeric components. These IPNs may be present in any golf ball layer, although in an intermediate or cover layer in one preferred embodiment. The present invention is also directed to methods of forming a golf ball containing an IPN in one or more of the layers. | 01-08-2009 |
