Abstract

PURPOSE: To provide title compsn. useful as sheet material, etc., obtd. by mixing a specified hardener with prepolymer obtd. from diphenylmethane diisocyanate, polytetramethyleneether glycol, etc., and curing the mixt.
CONSTITUTION: Prepolymer A which is liquid at a room temp. is produced by reacting (a) from 4W6eq. of a mixt. of diphenylmethane diisocyanate and carbodiimide-modified diphenylmethane diisocyanate which is liquid at a room temp. with (b) 1eq. of polytetramethyleneether glycol having an average MW of from 650W 2000 or a mixt. of said polytetramethyleneether glycol and aliph. diol having MW of 250 or lower. The prepolymer A is mixed with hardener B consisting of a mixt. of 1eq. of polytetramethyleneether glycol (b component), from 1W4eq. of diol having MW of 250 or lower acting as chain carrier and an organometallic catalyst in an eq. ratio of NCOgp./OHgp. of from 1W1.1. Then the mixt. is cured to produce title compsn.
