Abstract: Multi-layered golf balls having at least one layer made of a polyester composition containing a polyester thermoplastic elastomer and plasticizer are provided. The plasticizers help reduce the glass transition temperature (Tg) of the composition and various plasticizers may be used. For example, the composition may include alkyl oleate plasticizers such as ethyl oleate and octyl oleate. Polyester-ether block copolymers are particularly preferred. The golf ball includes a core having at least one layer and a cover having at least one layer. The polyester composition may be used to form any core, cover, or other layer in the golf ball.

Abstract: Golf balls having a solid multi-layered core and a cover are provided. The ball contains an inner core made of a foam composition, an intermediate core layer, and surrounding outer core layer. Preferably, foamed polyurethane is used to form the inner core and polybutadiene rubber is used to make the intermediate and outer cores. The specific gravity (density) of the inner core is preferably less than the density of the intermediate core, which is less than the outer core. The outer surface of the inner core preferably has a non-uniform structure and includes projecting members. The ball preferably has a high Moment of Inertia (MOI). The ball includes a single or multi-layered cover surrounding the core assembly.

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, and is formed from a substantially homogenous composition. The ball further includes an outer cover layer. The soft transition region has a thickness of up to 4 mm, has about 8 to 20 percent trans-polybutadiene isomer, and has a negative hardness gradient of up to 15 Shore C. The core has an overall negative hardness gradient of up to 20 Shore C and has a gradient quotient, GQ, defined by the equation: G + T 10 × COR ≤ 7 where G is the overall negative 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.

Abstract: A golf ball includes a core and a three-layer cover disposed adjacent the core. The three-layer cover includes an inner cover, an intermediate cover, and an outer cover. The inner cover includes a non-ionomeric E/Y copolymer where E is an olefin and Y is a carboxylic acid. The inner cover has a hardness of about 45 to 68 Shore D. The outer cover includes a castable thermoset polyurethane and has a hardness of about 40 to 62 Shore D. The intermediate cover layer, disposed between the inner and outer cover layers, is formed from a polyester composition including about 40 wt % to about 99 wt % of a polyester thermoplastic elastomer and about 1 wt % to about 60 wt % of a plasticizer.
