Abstract

PURPOSE: To prepare a polyfunctional low molecular weight polymer having terminal mercapto groups, by the reductive cleavage of polysulfide bonds of a copolymer composed of a sulfur compound and a monomer composition containing a polyfunctional (meth)acrylate.
CONSTITUTION: A polyfunctional low molecular weight polymer having terminal mercapto groups is prepared by the reductive cleavage of polysulfide bonds of a sulfur-containing polymer obtained by the terpolymerization of (A) a main component composed of a vinylidene group-containing monomer or its polymer, e.g. chloroprene, (B) a cross-linking agent comprising a poly-functional (meth)acrylate, e.g. ethylene glycol dimethacrylate, and (C) sulfur. The polymer is cured by the use of a proper curing agent such as a peroxide, to obtain an elastomer or a plastic, which can be used as a base polymer of a sealant, adhesive, a waterproof material, etc., or a modifier of rubber, liquid resin, asphalt, etc.
