An improved method is provided for producing polymers of organic compounds, such as ethylenically unsaturated monomers, containing a betaine-type group of the formula: ##STR1## The method involves the reaction of acrylic acid or aqueous methyl acrylate and an aminoalkyl (meth)acrylate or an N-amino-alkyl (meth)acrylamide having a basic tertiary nitrogen atom in the presence of a free radical initiator. The monomers undergo vinyl addition polymerization to form valuable polymers having a wide variety of uses, such as flocculants, retention aids in the deposition of polymers, pigments, etc. on the fibers in a paper pulp, e. g. , in the formation of mineral-filled papers.

A novel monomer composition for promoting wet adhesion of latex polymers for paints is provided. The composition consists essentially of a monomer having the formula: ##STR1## The preferred monomer is derived from the reaction of hydroxyethyl methacrylate with isophorone diisocyanate followed by reaction of the monourethane product the N-aminoethyl ethylene urea. The monomer is preferably copolymerized in an emulsion polymerization with acrylic and/or vinyl monomers.

There is provided a polymer useful in coating, ink and adhesive compositions. The polymer has monomeric units derived from a monomer having the formula: ##STR1## wherein: R. sup. 1 is alkylene having about 2 or 3 carbon atoms; R. sup. 2 is alkylene having about 2 to about 10 carbon atoms; X is oxygen, sulfur, or NR. sup. 3 wherein R. sup. 3 is hydrogen, alkyl, alicyclic, aryl, heteroalkyl, heterocyclic; R. sup. 4 has the structure of the residue of an alicylic diisocyanate wherein the isocyanate groups have reactivities that differ one from another; Y is oxygen, sulfur, or NR. sup. 5 wherein R. sup. 5 is hydrogen, alkyl, alicyclic, aryl, heteroalkyl, or heterocyclic; R. sup. 6 is alkylene, arylene, aralkylene, alkarylene, or heteroalkylene; Z is oxygen, sulfur, or NR. sup. 7 wherein R. sup.

An effective autodeposition bath with low volatile organic compound emissions can be compounded with polymer solids made by polymerizing a mixture of monomers consisting of certain acrylates and other monomers. E. g. , a suitable mixture is, in percents by weight, 44% butyl acrylate, 36% acrylonitrile, 10% styrene, 7% methacrylic acid, 2% of the methyl ether of methacrylamide, and 1. 5% of hydroxyethyl acrylate.

The present invention is concerned with new and improved binders for the production of foamed or cellular articles which have a high degree of absorbency, and retain their bonded character as well as absorbency through numerous wash-dry cycles. The cellular articles are bonded by a novel self-cross-linking binder comprising a copolymer of (a) N-methylol-amine or -amide units, (b) sulfonic acid units which contain no basic nitrogen atoms or group, and (c) certain acrylic units of neutral but mildly hydrophilic character which contain no basic nitrogen atoms or group.
