Abstract

Novel polyacrylic acid resins are prepared by polymerizing a monomer selected from the group consisting of H.sub.2 C.dbd.CHCO.sub.2 X, H.sub.2 C.dbd.CR.sup.1 CO.sub.2 X, HR.sup.2 C.dbd.CHCO.sub.2 X, HR.sup.2 C.dbd.CR.sup.1 CO.sub.2 X, HR.sup.2 C.dbd.CHCOX, H.sub.2 C.dbd.CHCOX, H.sub.2 C.dbd.CR.sup.1 COX, HR.sup.2 C.dbd.CR.sup.1 COX, H.sub.2 C.dbd.CHCSO.sub.v X, HR.sup.2 C.dbd.CHCSO.sub.v X, HR.sup.2 C.dbd.CR.sup.1 CSO.sub.v X, H.sub.2 C.dbd.CR.sup.1 CSO.sub.v X, H.sub.2 C.dbd.CHCON(R.sup.3).sub.2, HR.sup.2 C.dbd.CHCON(R.sup.3).sub.2, H.sub.2 C.dbd.CR.sup.1 CON(R.sup.3).sub.2, OR HR.sup.2 C.dbd.CR.sup.1 CON(R.sup.3).sub.2, or a combination thereof, in the presence of at least 10% by weight of reaction components of an aromatic sulfonic acid or its salt, wherein: R.sup.1 and R.sup.2 are independently a substituted or unsubstituted alkyl, alkenyl, aromatic, aralkyl or alkaryl moiety of C.sub.1 to C.sub.20 ; R.sup.3 is independently hydrogen or a substituted or unsubstituted alkyl, alkenyl, aromatic, aralkyl or alkaryl moiety of C.sub.1 to C.sub.20 ; and X is hydrogen, substituted or unsubstituted alkyl, alkenyl, aromatic, aralkyl, or alkaryl moiety of C.sub.1 to C.sub.20 ; --CH.sub.2 …
