Abstract
Disclosed are ethylenically unsaturated salts of allyl (poly)ether sulfates utilized as reactive surfactants or emulsifiers during emulsion polymerization.
Claims21
A polymerizable surfactant composition comprising:
- a polymerizable surfactant of formula (I):
- wherein R1 is a bicyclo[d,e,f]heptyl or bicyclo[d,e,f]heptenyl group wherein d is 2, 3, or 4, e is 1 or 2, f is 0 or 1, and the sum of d+e+f=5, and which may, optionally, be substituted on one or more of the ring carbon atoms by one or more (C1-C6)alkyl groups;
- wherein “x” is an integer from 1-40,
- wherein “y” is an integer from 1-50;
- wherein M+ is H+, Na+, NH4+, K+ or Li+;
- and optionally, at least one surfactant.
