| titleOfInvention | Polymerization of vinyl chloride |
| abstract | A process for polymerizing a vinyl chloride monomer wherein the vinyl chloride monomer is subjected to homopolymerization or (co)polymerization with a monomer copolymerizable with the vinyl chloride monomer in an aqueous solvent, comprising applying in advance a coating liquid containing a cocondensation product obtained by reacting either a phenothiazine derivative and an aldehyde or a phenothiazine derivative, a naphthol derivative and an aldehyde to give an initial condensation product and then reacting the initial product with a polyphenol, to an inner wall of a polymerization tank and parts of an apparatus in contact with the monomers during the polymerization process. The process makes it possible to apply the cocondensation product as an aqueous solution to, e.g., an inner wall of a polymerization tank; to quite effectively prevent polymer adhesion in, e.g., a polymerization tank, without affecting a polymerization rate or physical properties of the product; and thus to eliminate the need for removing adhered polymer after every polymerization process and to realize closed polymerization in which a manhole should not be opened for every polymerization process. |
