Abstract
PURPOSE: To obtain the titled composition giving a cured elastomer having excellent flex-crack resistance and cut resistance, by compounding a liquid diene polymer with a plyether having a specific range of number-average molecular weight and carbon black having specific particle size.
CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of a diene polymer having active hydrogen group (e.g. polybutadiene homopolymer), (B) 5W1,000pts., pref. 10W500pts. of a polyether containing active hydrogen group and having a number-average molecular weight of 4,000W20,000, pref. 4,500W15,000, and (C) 5W200pts., pref. 20W100pts. (based on 100pts of A+B) of carbon black having an average particle diameter of ≥60mμ, and stirring the mixture under heating.
