    Abstract: Multi-layered golf balls containing a two or three-layered cover assembly are provided. In one embodiment, the cover assembly includes a relatively hard inner cover and relatively soft outer cover. Alternatively, the cover assembly may include a relatively soft inner cover with a relatively hard outer cover. Three-layered covers comprising an inner cover, intermediate cover, and outer cover layer also may be prepared. Preferably, at least one of the layers is formed from a thermoplastic composition that preferably comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. The cover assembly has good impact durability and helps provide the ball with relatively high resiliency at given compressions.

    Abstract: The present invention is directed to a golf ball layer formed from an injection molding process using a retractable pin injection mold. The injection molding process includes retracting pins beyond the molding surface of the mold at the end of the injection cycle to form surface protrusions at the various pin locations and removing the protrusions in a post molding process. The injection molding process of the present invention results in golf ball layers having reduced molded in stresses and defects and enhanced durability.

    Abstract: Golf balls having multi-layered covers and single or multi-layered cores are provided. The cover includes an inner cover layer made of an aromatic polyurethane composition; and outer cover layer made of an aliphatic polyurethane composition. Ethylene acid copolymer ionomers can be used to make a second inner cover layer. Preferably, the total thickness of the multi-layered cover is preferably no greater than 0.110 inches. Thermoplastic and thermoset polyurethanes can be used to form the cover. The invention also includes casting methods for making such multi-layered covers. The resulting ball has good light-stability, cut/shear-resistance, and impact durability.

    Abstract: A golf ball having improved adhesion comprising: a core; a first layer surrounding the core; a tie layer surrounding at least a portion of an outer surface of the first layer and consisting of a mixture of a polyfunctional aziridine compound and a solvent; and a second layer that is different than the first layer formed about the tie layer. The first layer may consist of a non-urethane composition whereas the second layer consists of at least one urethane composition. The first layer may comprise a non-urethane composition whereas the second layer consists of at least one urethane composition. The first layer may consist of a non-urethane composition while the second layer comprises a urethane composition. The first layer may comprise an ionomer for example. The solvent may be aprotic. Alternatively, the solvent may be protic.

    Abstract: A golf ball includes a unitary core having an outer surface, a geometric center, and a soft transition region adjacent to the outer surface. The core is formed from a substantially homogenous composition. An outer cover layer is formed over the core. The soft transition region has a thickness of up to 4 mm, includes about 15 to 30 percent trans-polybutadiene isomer, and has a negative hardness gradient of up to about 10 Shore C. The unitary core has an overall positive hardness gradient of about 15 to 22 Shore C and has a gradient quotient, GQ, defined by the equation: 5 ≤ G + T 10   x   COR ≤ 6 where G is the overall positive hardness gradient in Shore C, T is the percent of trans-polybutadiene isomer at the core outer surface, and COR is the coefficient of restitution measured at an incoming velocity of 125 ft/s.
