| titleOfInvention | Polymer scale preventive agent and process of producing polymer using the same |
| abstract | The polymer scale preventive agent comprises an alkaline solution containing (A) an condensation product of (A-1) a hydroxybiphenyl compound with (A-2) an aldehyde compound, (B) a reaction stopper, and (C) an inorganic colloid and is used for polymerization of a monomer having an ethylenically unsaturated double bond. The process of producing the polymer comprises polymerizing the monomer in a polymerization vessel having a coating film on its inner wall surfaces, whereby polymer scale is prevented from being deposited, wherein said coating film is formed by applying, on said inner wall surfaces, said alkaline solution, followed by drying. According to the invention, deposition of polymer scale can be effectively prevented not only on the areas in the liquid phase but also at and in the vicinity of the interface between the gas and liquid phases in a polymerization vessel. Therefore, the invention does not require to conduct the operation of removing the polymer scale after every polymerization run, whereby the productivity is improved. Further, when the polymeric product obtained using the method of the invention is processed into formed products such as sheets, the resulting formed products have very few fish eyes. In addition, the formed products obtained as above are low in initial coloration. |
