BASIC MAGNESIUM SULFATE-DISPERSED DIENE POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a basic magnesium sulfate-dispersed diene polymer in which inorganic fibers of basic magnesium sulfate are dispersed uniformly in a diene polymer.SOLUTION: A basic magnesium sulfate-dispersed diene polymer comprises inorganic fibers (A) of basic magnesium sulfate, a higher fatty acid (B) and a diene polymer (C). The higher fatty acid (B) is preferably stearic or linolenic acid. The basic magnesium sulfate-dispersed polymer is usable as a basic magnesium sulfate master batch for rubber compositions.
