Abstract
PURPOSE: A rubber composition that is composed of a rubber and low-molecular- weight polymer, does not stain molds and has good physical properties.
CONSTITUTION: To 100 parts by wt of a rubber such as polybutadiene or a rubber containing more than 30wt% of butadiene are added 0.01W5, preferably 0.1W2 parts of a low-molecular-weight polymer with a molecular weight of 5-W10000, preferably 1000W5000 that contains propylene as the structural unit such as polypropylene, or etheylene-propylene copolymer of ethylene-propylene-nonconjugated diene terpolymer.
