Reactive surfactants for emulsion polymerization, pigment dispersion, and UV coatings
The present invention provides reactive surfactants of the formula R 1 O—(CH 2 CHR 2 O) x —(CH 2 CH 2 O) y —(CH 2 CHR 3 O) z —R 4 where R 1 is either alkyl, aryl, alkylaryl, or aralkylaryl of 8-30 carbon atoms, R 2 is —CH 2 OCH 2 CH═CH 2 (AGE); R 3 is either H, CH 3 , or CH 2 CH 3 ; R 4 is H or —SO3M or —PO3M where M is H or K, Na, NH4, NR4, alkanolamine, or other cationic species and x=2-100; y=4-200 and z=0-50.
1. A compound selected from the group consisting of:
where R═CH 3 or CH 2 CH 3 , n=1, 2, 3; x is 2-10, y is 0-200, z is from 5 to 40; Z can be either SO 3 − or PO 3 2− , and M + is Na + , K + , NH 4 + , or an alkanolamine;
where R═CH 3 or CH 2 CH 3 , n=1, 2, 3; x is 2-10, y is 0-200, z is from 5 to 40;
