HARD GOLF BALL REINFORCED THROUGH SOLVENT MASTER BATCH BY USING METALLIC SALT OF ALPHA,BETA-ETHYLENICALLY UNSATURATED CARBOXILIC ACID

摘要

PURPOSE:To provide a hard golf ball having a high physical property by uniformly mixing metallic salt of alpha,beta-ethylenically unsaturated carboxilic acid through solution master batch into rubber-like polymer. CONSTITUTION:Polymer cement is producedin proper aliphatic hydrocarbon solvent. Suspension is formed in the hydrocarbon solvent miscible with hydrocarbon solvent of metallic salt of alpha,beta-ethylenically unsaturated carboxilic acid. The polymer cement is mixed with the suspension to remove the solvent and provide the metallic salt uniformly dispersed in the polymer. Then, a hard golf ball is produced from these materials.
