Method for polymerizing vinyl monomers in a coated reactor

摘要: A process for producing a polymer by polymerizing in polymerization vessel monomer having an ethylenic double bond is provided. In this process, the has scale preventive coating film on its inner wall surfaces and other with which comes into contact during polymerization. The formed liquid containing (A) compound selected from group consisting of aromatic 5 or more conjugated π bonds heterocyclic bonds, (B) inorganic colloid, chelate reagent, metal that produces ion capable forming complex at least two coordination numbers, acid; being coated means steam as carrier. This can shorten time films agents to improve productivity, effect preventing scales, make colored particles less mix products, lessen fish eyes initial discoloring products quality polymeric their molded products.
