    摘要： Low compression multi-piece golf balls having a solid core comprising at least one layer made of a plasticized thermoplastic composition are provided. Preferably, the ball has a compression of less than 60 and more preferably less than 50. The ball includes a cover in addition to the core sub-assembly. For example, two-piece and three-piece golf balls may be made. The plasticized thermoplastic composition preferably comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. Preferably, a fatty acid ester such as butyl oleate is used as the plasticizer. In two-layered core constructions, the outer core layer is preferably formed from a thermoset composition such as polybutadiene rubber. The core layers may have different hardness levels. The core structure and resulting ball have relatively good resiliency at given compressions.

    摘要： Golf ball with a central cavity (6, 23) having an RFID/electronic tag (4, 24) located therein. The tag is immersed in a medium (5) which, in response to striking of the ball, flows around the tag to damp transitional movement and vibration. For retro-fit of an already-manufactured standard ball, entry of aqueous liquid into the cavity (6) is from a borehole-opening (3) which is centered within a dimple of the outer cover (1) of the ball and sealed (8), following introduction of a gelling agent (9). After the central cavity (22) is filled with a liquid medium (23), it is closed by a plastics plug (25). The tag (42) of a used/damaged ball (39) can be retrieved and recycled by an automated machine (30) that cuts a circumferential slit (40) through the cover and then impacts blades of a chisel (38) split the ball in two to reveal the tag.
