Definitions
- the present invention relates to a thermoplastic resin composition having excellent flexibility and rebound resiliency. More specifically, the invention relates to a thermoplastic resin composition that can be favorably used as a cover material and/or a core material of golf balls or as a material for one piece balls, that features excellent injection moldability and that can be reused.
- ionomer resins made from ethylene-unsaturated carboxylic acid copolymers have been extensively used as cover materials for golf balls.
- the golf balls using a conventional general-purpose hard ionomer as the covering material offer unsatisfactorily low spin performance and undesirable feel at the time of hitting the ball in comparison with golf balls using balata as the covering material. Therefore, attempts have heretofore been made to improve such performance and feel by blending flexibility-imparting components.
- thermoplastic elastomer such as polyester elastomer or polyamide elastomer in order to obtain a composition having flexibility yet exhibiting excellent rebound resiliency.
- thermoplastic elastomer is expensive and. besides, the durability of the composition decreases with an increase in the amount of blending thereof: Therefore, it has been desired to decrease the blending amount of the thermoplastic elastomer blended with the ionomer to as low a level as possible. In other words, it has been desired to decrease amount of thermoplastic elastomer while obtaining a composition that exhibits both flexibility and rebound resiliency.
- the rebound resiliency of the composition decreases with an increase in the blending amount of the ionomer component, and the hardness and the stiffness become too high.
- a polybutadiene rubber has generally been used as the core material for two-piece balls, center for three-piece balls or as the material of one- piece balls.
- This cross-linked rubber has problems in regard to moldability and producibility. Besides, the used balls cannot be recycled for another use.
- a composition of the ionomer and the thermoplastic elastomer is free from such defects and is drawing attention as a core material or as a material for one piece balls accompanied, however, by the problems similar to those of the above-mentioned cover material.
- the object of the present invention is to find compositions comprising an ionomer and a thermoplastic elastomer that make it possible to obtain balls that exhibit excellent flexibility, excellent rebound resiliency, excellent durability, good feel at the time of hitting the ball, and that can be easily controlled. It has been found that the object can be accomplished when a particular ionomer modified with a particular amine is used.
- a thermoplastic resin composition is obtained that is suited as a material for golf balls.
- thermoplastic resin composition comprising:
- thermoplastic resin composition of the present invention exhibits excellent flexibility and rebound resiliency, and lends itself well for being used as a material for forming a center of a three-piece golf ball, core of a two-piece golf ball, for forming a one-piece golf ball, a cover of golf balls, and an outer cover or an inner cover of dual golf balls, making it possible to produce golfs balls having excellent durability, good controllability (higher spin), good feel at the time of hitting, excellent rebound resiliency and improved initial velocity.
- the present resin composition is thermoplastic and can be easily molded by the injection molding or compression molding, and can be molded and produced very excellently compared with the conventional cross-linked butadiene rubbers, and can further be reused (recycled). Moreover, the present resin composition exhibits excellent resistance against being scratched and scarred, resistance against oils, and exhibits luster. It can be widely used as interior and exterior materials for automobiles, electric wires, cables, building materials, electric appliances, commodities for daily use, or the like.
- an alicyclic or an aromatic compound (and, particularly, a condensed cyclic compound) having two or more aminoalkyi groups is selected out of a variety of amines and is combined with a multi-valent metal ionomer to obtain a modified composition.
- the ionomer composition modified with the aminoalkyi group-containing compound gives an advantage of improving the rebound resiliency without impairing flexibility of the final composition.
- the ionomer that is modified is one neutralized with a multi-valent metal.
- Ionomer neutralized with a monovalent metal when modified with the aminoalkyi compound does not exhibit so much an effect as when a multi-valent ionomer.
- zinc ionomer is modified with the aminoalkyi compound.
- the modified ionomer composition (A) is combined with the thermoplastic elastomer (B) selected from the group consisting of a thermoplastic polyester elastomer and a polyamide elastomer.
