Abstract
Official abstract text for this publication.
A center of a golf ball is formed from a composition having a flexural modulus from 150-450 MPa, a maximum loss factor (tan δ) between −20 and 0° C. of 0.08 or less, a rebound resilience of 55% or more, and a slab hardness ranging from 40-60 in Shore D hardness. The center composition includes, as a resin component, 30 to 70 mass % of (A) a modified polyester elastomer having a Shore A hardness of 95 or less; 70-30 mass % of (B) a binary ionomer resin having a Shore D hardness of 65 or more, a flexural modulus of 300 MPa or more, and a melt flow rate (190° C., 2.16 kg) of 1.0 g/10 min or more; and 0-50 mass % of (C) a thermoplastic resin other than (A) and (B) components (provided that a total content of (A), (B), and (C) components is 100 mass %).
First claim
Opening claim text (preview).
The invention claimed is: 1.
