Where the monomer is polymerized in a polymerization vessel having, on its inner wall surface, a coating comprising the preventive agent, deposition of polymer scale can be effectively prevented not only on the liquid phase part in the polymerization vessel but also near the interface between the gas phase part and the liquid phase part, so that the thus obtained polymer can provide a molded item having few fish eyes and low in initial coloration, when the polymer is molded into a sheet or the like.摘要翻译： 一种用于聚合具有烯键式不饱和双键的单体的聚合物垢预防剂，其包含通过缩合（A）脂族二胺化合物和（B）醌化合物而得到的缩合产物。 在水性介质中。 当单体在内壁表面上具有包含防止剂的涂层的聚合容器中聚合时，聚合物垢的沉积不仅可以有效地防止在聚合反应器中的液相部分，而且可以靠近聚合反应器之间的界面 气相部分和液相部分，从而当聚合物被模塑成片材等时，由此获得的聚合物可以提供具有少量鱼眼并且初始着色低的模制品。

摘要： A polymer scale preventive agent for use in polymerization of a monomer having an ethylenically unsaturated double bond, comprising an alkaline solution containing a condensation product of (A) an aromatic amine compound having at least two amino groups and (B) an aromatic tetracarboxylic acid anhydride. This agent is used for forming a coating on the inner wall, etc. of a polymerization vessel. Such a vessel is effective in preventing polymer scale deposition and useful in producing a polymer that shows very few fish eyes and good whiteness when formed into sheets or the like.

摘要： A polymer scale preventive agent used for polymerizing a monomer having an ethylenically unsaturated double bond, comprising an alkaline solution containing (A) an anthraquinone dye and (B) a reducing agent. Where the monomer is polymerized in a polymerization vessel having, on the inner wall surface, a coating film formed by applying and drying said preventive agent, polymer scale can effectively be prevented from being deposited not only on the liquid phase part in the polymerization vessel but also near the interface between the gas phase part and the liquid phase part, so that the thus obtained polymer can provide a molded item having few fish eyes, when the polymer is molded into a sheet or the like.

摘要： A method of preventing polymer scale deposition in a polymerization vessel in polymerization of a particular monomer having an ethylenic double bond having a high dissolving power against the conventional scale preventive coatings, wherein said polymerization is carried out in a polymerization vessel of which the inner wall has been previously coated with a first coating solution comprising:
(A) a water-soluble anionic dye, and (B) at least one member selected from the group consisting of inorganic colloids and cationic dyes, to form a first coating, and the first coating thus formed has been then coated with a second coating solution comprising: (C) an alkaline earth metal compound, and at least one member selected from the group consisting of: (D) a water-soluble anionic dye and (E) an inorganic colloid, to form a second coating. The polymerization vessel having the double coating as prepared above is also disclosed. Polymer scale deposition can be effectively prevented.-

摘要： A method of preventing polymer scale formation in a polymerization vessel during the polymerization of a monomer having an ethylenically double bond, wherein said polymerization is carried out in a polymerization vessel in which its inner wall surface has been previously coated with a coating solution containing (A) at least one member selected from the group consisting of particular anionic dyes, and alkali metal salts and ammonium salts of a sulfonated product obtained by sulfonation of a condensate of a particular aromatic amine compound with a particular aromatic nitro compound, and (B) a particular cationic dye and having a pH of more than 7, and then dried to form a coating. This method can effectively prevent scale formation in the polymerization of extensive monomers having an ethylenically double bond, so that 100 or more polymerization runs can be repeated without formation of polymer scale.
