| titleOfInvention | A polymeric crust deposition inhibitor and a method of making vinyl chloride polymers using it |
| abstract | The present invention relates to an agent for inhibiting polymer crust deposition and to a process for the production of a vinyl chloride polymer using said agent. The polymeric anti-fouling agent of the present invention contains an alkaline solution of a dimeric compound of 2,3-dihydroxynaphthalene and a condensation product of formaldehyde having a molecular weight of 500 to 1,000,000. According to the invention, vinyl chloride polymers are prepared by polymerizing vinyl chloride monomer or vinyl monomer mixtures containing predominantly vinyl chloride monomer by polymerizing amonomers in a polymerization vessel in which the inner wall surface and the monomer or the methyl A polymeric anti-fouling coating film containing an alkaline solution of a condensation product having a weight of 500 to 1,000,000 molecular weight obtained by condensing a dihydroxynaphthalene dimer compound and formaldehyde was formed. Using the agent according to the invention, a high-quality vinyl chloride polymer with a small amount of colored foreign matter and fish eyes can be produced, which is characterized by a slight initial discoloration. ŕ |
