Abstract
Compounds of the formula: EQU CH.sub.2 .dbd.C(R)--COO--(CH.sub.2 --CH(CH.sub.3)--O).sub.x --(CH.sub.2 --CH.sub.2 --O).sub.y --OC--A--COOH or a salt thereof, wherein PA1 R is H or CH.sub.3, PA1 x is an integer from 2 to 20. PA1 y is an integer from 0 to 5, PA1 A is an alkylene, alkenylene, or phenylene radical such that A(COOH).sub.2 is a dibasic acid capable of forming an anhydride (A(CO).sub.2 O, are described. These are polymerizable compounds which have also surfactant properties. The compounds may be used to replace non-polymerizible surfactants in emulsion polymerization reactions, and preferably in those reactions which result in adhesive polymers which are suitable for surgical and medical use. Methods for preparing the compounds and pressure sensitive adhesives formed by copolymerization of the compounds with other acrylate monomers are also described.
