Abstract: Golf ball incorporating mixtures of thermoplastic polymers and polymethyl methacrylate (MMA) copolymers. The thermoplastic polymer and MMA copolymers may be included in weight ratios of from 98:2 to 50:50. The mixture may have different hardness than that of the thermoplastic polymer, a glass transition temperature Tg-m greater than a glass transition temperature Tg-tp of the thermoplastic polymer, and a modulus, tensile strength and ultimate elongation greater than that of the thermoplastic polymer.

Abstract: A golf ball including a dual core comprising an inner core having a first outer surface, a geometric center, and a soft transition region adjacent to the outer surface, and an outer core layer having a second outer surface disposed about the inner core. An inner cover layer and an outer cover layer are formed over the core. The second outer surface is greater than the first outer surface to define a dual core overall positive hardness gradient of about 25 Shore C to 35 Shore C and has a secondary gradient quotient, GQ′, defined by the equation: 6 ≤ G ′ + T 10 × COR ≤ 7 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.

Abstract: Multi-layered golf balls containing a dual-core structure are provided. The core structure includes an inner core (center) comprising a foam composition, preferably foamed polyurethane. The outer core layer is preferably formed from a non-foamed thermoset composition such as polybutadiene rubber. The core layers have different hardness and specific gravity levels. The specific gravity (density) of the foam inner core is preferably less than the density of the outer core layer. The core assembly preferably has a positive hardness gradient extending across the entire assembly. The core structure and resulting ball have relatively good resiliency.

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: Methods for making golf balls and golf ball components using three-dimensional (3D) additive manufacturing systems are provided. The golf ball includes at least one three-dimensional piece. Preferably, a continuous liquid interface printing method is used to make the three-dimensional structure. Ultraviolet (UV)-light polymerizable materials are used in the method. The method may be used to make single-piece or multi-piece balls. For example, the ball may include an inner core produced by the liquid interface printing method. An outer core layer may be disposed about the inner core, and a cover comprising inner and outer cover layers may encapsulate the core assembly to form the finished golf ball. The outer core and cover layers may be made using conventional molding technologies or methods of this invention.
