め廃水負荷が軽減出来る。The emulsifier for emulsion polymerization of the present invention is characterized in that it has a (meth) acrylic group which is a copolymerizable double bond and is a carboxylic acid or a salt thereof as an anionic hydrophilic group.
Compared with the conventional sulfonate or sulfate ester type reactive emulsifiers, the polymers and polymer films produced from emulsions obtained by emulsion polymerization have excellent heat resistance. When an inorganic salt or an acid is added after the emulsion polymerization and the polymer is taken out, the emulsifier for emulsion polymerization of the present invention is a carboxylic acid salt, so that the acid turns into a carboxylic acid, and the aggregation of the polymer is very easy. Furthermore, since the free liquid emulsifier hardly exists in the waste liquid after polymer coagulation, the waste water load can be reduced.
