Title:
ポリカルボン酸系重合体の製造方法
Document Type and Number:
Japanese Patent JP6415584
Kind Code:
B2
Abstract:
Provided is a method of producing a polycarboxylic acid-based polymer, the method including adding a monomer composition containing an unsaturated monocarboxylic acid-based monomer and/or an unsaturated dicarboxylic acid-based monomer to a reaction vessel to perform a polymerization reaction, which enables effective suppression of the foaming of a polymerization reaction liquid. The method of producing a polycarboxylic acid-based polymer of the present invention is a method of producing a polycarboxylic acid-based polymer, the method including adding a monomer composition containing an unsaturated monocarboxylic acid-based monomer and/or an unsaturated dicarboxylic acid-based monomer to a reaction vessel to perform a polymerization reaction, the method further including adding a defoaming agent by a time when 100 mass % of a total amount of the monomer composition is added.
