ABSTRACT:
In the polymerization of vinyl chloride monomer or a mixture of vinyl monomers having vinyl chlorides as a main component, the deposition of polymer scale on the inner walls of the polymerization vessel can be effectively reduced by coating the internal surfaces of the reactor with first, a condensation polymer of a polyhydric phenol and an aldehyde and second, a crosslinking agent to increase the insolubility of the polymeric material.
