Abstract

PURPOSE: To obtain the titled composition which gives a cured product suitable for puncture-proof tire packing, and prominent in elasticity and low temp. performance, by compounding a polyether polyol to an isocyanate-terminated prepolymer contg. liq. diene polymer.
CONSTITUTION: One or more compds. contg. at least liq. diene polymer selected from liq. diene polymer contg. active hydrogen (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. To the resulting prepolymer is compounded polyether polyol (ethylene oxide adduct) of MW 700W5,000 in an NCO/OH ratio of about 0.8W1.5.
