Abstract:
A process for producing a polymer by polymerizing in a polymerization vessel a monomer having an ethylenic double bond, whereinsaid polymerization vessel has a polymer scale preventive coating film on its inner wall surfaces and other surfaces with which the monomer comes into contact during polymerization; said coating film being formed by coating a coating liquid containing: (A) a compound selected from the group consisting of an aromatic compound having 5 or more conjugated &pgr; bonds and a heterocyclic compound having 5 or more conjugated &pgr; bonds; and (B) at least one compound selected from the group consisting of an inorganic colloid, a chelate reagent, a metal compound that produces a metal ion capable of forming a complex having at least two coordination numbers, and an acid; said coating liquid being coated by means of steam as a carrier.
