Abstract
Multi-layered golf balls having at least one layer made of a foamed silicone composition are provided. Multi-layered golf balls having at least one layer made of non-foamed silicone elastomer composition also are provided. For example, three-piece, four-piece, and five-piece golf balls containing different core and cover structures can be made. The foamed silicones have good thermal stability and durability without sacrificing resiliency. The non-foamed silicone elastomers have high elongation, tensile strength, chemical/fluid-resistance, and weatherability properties. These compositions can be used to form any layer, for example, core, intermediate, or cover, in the golf ball.
Claims15
A golf ball having at least one layer formed from a silicone elastomer composition, wherein the silicone elastomer composition is made from at least one heterobifunctional macromer.
A golf ball having at least one non-foamed layer formed from a silicone elastomer composition, wherein the silicone elastomer has a degree of polymerization of from 10 to 100 and a molecular weight of from 900 to 7,600.
A golf ball having at least one non-foamed layer formed from a silicone elastomer composition, wherein the silicone elastomer has a degree of polymerization of from 5,000 to 10,000 and a molecular weight of from 370,000 to 740,000.
