EMULSIFYING AGENT FOR EMULSION POLYMERIZATION

摘要

122a32b322233An emulsifying agent for reactive emulsion polymerization which is composed of a compound represented by general formula (I) enables achievement of good polymerization stability during emulsion polymerization and is capable of remarkably improving water resistance adhesion heat resistance weather resistance and the like of a polymer film that is obtained using the emulsifying agent. In formula (I) D represents a polymerizable unsaturated group represented by chemical formula D 1 or D 2; m1 represents a number not less than 1; R represents an alkyl group having 1 12 carbon atoms; m2 represents a number of 0 4 with the total of m1 and m2 being 1 5; R represents a hydrocarbon group having 6 30 carbon atoms; A represents an alkylene group having 2 4 carbon atoms or a substituted alkylene group; n represents an average mole number of added alkylene oxides which is within the range of 0 1 000; and X represents a hydrogen atom or an anionic hydrophilic group selected from among (CH) SOM  (CH) COOM  POM  P(Z)OM and CO CH CH(SOM) COOM. In chemical formula D 1 and chemical formula D 2 R represents a hydrogen atom or a methyl group.
