摘要： Novel, soft, low modulus ethylene copolymer ionomer compositions containing an acrylate softening monomer, neutralized with magnesium or lithium ions possess a higher level of resilience at a given level of PGA Compressibility than known ionomers. The advantage is maintained in certain blend compositions with harder ionomers for blends having a neat-sphere PGA Compression below about 155. Both unblended and blended compositions will be useful as golf balls and components of golf balls, for one-piece balls, centers, cores and covers of golf balls.

摘要： A two-piece golf ball comprising of a core formed of a rubber composition containing a base rubber, a co-crosslinking agent, and an organic peroxide, and a cover covering the core, characterized in that:
the core has the following hardness distribution according to JIS - C type hardness meter readings:
(1) hardness at centre : 58 - 73 (2) hardness 5 to 10 mm from centre : 65 - 75 (3) hardness 15 mm from centre : 74 - 82 (4) surface hardness : 76 - 84
(wherein hardness (2) is generally constant within the range shown, with a variation range of ±3, and satisfies the relation (1)
the core has a compression deflection of 3.5 to 4.3 mm when a load range of initial 10 kg to final 130 kg is applied, the cover having a thickness of 2.1 to 2.8 mm.
