Abstract
PURPOSE: To provide an adhesive for vulcanized rubber, which has high bond strength and improves bonding operation, containing a polymer obtd. by reacting a blocking agent with a polyisocyanate and then reacting the resulting reaction product with a polyhydroxyhydrocarbon polymer.
CONSTITUTION: A polyisocyanate is reacted with a blocking agent for isocyanate gp. in an amount of 0.1W0.7mol of the blocking agent per one equivalent of the isocyanate gp. in the polyisocyanate. The resulting reaction product is reacted with a polyhydroxyhydrocarbon polymer to obtain a curable polymer in which free isocyanate gp. are absent. This curable polymer or a compsn. consisting of the curable polymer and the blocked polyisocyanate in which free isocyanate gp. are absent, is used as an adhesive for vulcanized rubber. When the reaction product of the blocking agent with the polyisocyanate is reacted with the polyhydroxyhydrocarbon polymer, the reaction is carried out in an equivalent ratio of the isocyanate gp. to the hydroxyl gp. of the polyhydroxyhydrocarbon polymer of 0.6W2.0.
