Abstract

PURPOSE: A urethane prepolymer having improved storage stability, curable at normal temperature, preparing an elastomer with improved mechanical properties, obtained by reacting an organic polyisocyanate with a diol having a specific structure and a polyol.
CONSTITUTION: (A) an organic polyisocyante (e.g., tolylene diisocyanate, etc.) is reacted with (B) an aromatic ring-containing diol [e.g., bis(β-hydroxyethoxy) resorcinol, etc.] shown by the formula I [R1 is a group shown by the formula IIW V, etc.; R2 and R3 are a group shown by the formula VIWVIII (R4 is 1W10C alkylene), etc.] and (C) a polyol (preferably polyprolylene glycol, etc.) having a molecular weight 300W10,000 (preferably 350W5,000) preferably at 50W100°C, to give a urethane prepolymer having an isocyanate group content 2W10wt%. An amount of the ingredient B is preferably 1W10wt% based on C.
USE: An elastomer obtained by adding a curing agent, followed by curing, is suitable as a sealing material, coating material, etc.
