摘要:
Asphalt emulsions are rapidly hardened by incorporating therein an isocyanate-terminated urethane prepolymer formed by reacting one equivalent of the OH group of a polyalkylene glycol having the following formula ##EQU1## wherein p + r .gtoreq. q, q .gtoreq. O, p .gtoreq. 1, r .gtoreq. 1 and 20 .ltoreq. p + q + r .ltoreq. 100, with 1.1 to 2.0 equivalents of the NCO group of an organic diisocyanate.
