Abstract

PURPOSE: To obtain the titled composition which gives a cured product suitable for picture-proof tire packing, and prominent in elasticity and low temp. performance, by compounding a polyol derived from castor oil to an isocyanate- terminated prepolymer contg. liq. diene polymer.
CONSTITUTION: One or more compds. contg. at least liq. diene polymer selected from active hydrogen-contg. liq. diene polymer (e.g., polybutadiene homopolymer), polyether polyol (e.g., ethylene oxide adduct), and castor oil-based polyol are reacted with an organic diisocyanate (e.g., tolylene diisocyanate) to prepare an isocyanate-terminated prepolymer. Tri- or higher functional castor oil-based polyol having hydroxyl equivalent of 220W500 is compounded to the resulting prepolymer in an NCO/OH ratio of about 0.8W1.5.
