Abstract

PURPOSE: A sealing material that is composed of a specific modified low-molecular diene polymer and a curing agent therefor, thus being good at safety and health and having high rubber elasticity, adhesion to metal, glass, pottery, slates, etc., heat and weathering resistances.
CONSTITUTION: Said sealing material comprises (A) a modified low molecular weight diene polymer that is made by adding (a) 0.1W20mol%, based on the diene monomer, of maleic anhydride and or its derivative to a low molecular weight diene polymer of 10,000W150,000 molecular weight, (B) a curing agent as sulfur, an amine, a zinc compound, or an epoxy compound. The polymer A is preferably a polyisoprene obtained by using a lithium catalyst.
