Abstract: Low molecular weight addition copolymers, of (1) (meth)acrylic acid esters of alcohols such as methanol and butanol with (2) esters of alcohols such as N-(.beta.-hydroxyethyl)oxazolidine and unsaturated acids such as a (meth)acrylic acid, and (3) optional .alpha.,.beta.-ethylenically unsaturated monomers such as a (meth)acrylic acid, are found to be exceptional dispersants for inorganic and organic pigments and colorants which are insoluble in organic solvents, for lacquers, and are compatible with practically all types of lacquer resins such as vinyls, nitrocellulose, and alkyds, and with many other types of lacquer film-forming materials. Usually, when small amounts of unsaturated carboxylic acids, or other polar monomers and combinations thereof, are incorporated in the polymers, they become improved pigment dispersants. Such pigment dispersions, unexpectedly, can be let down with many types of synthetic resins and used by air-drying or baking the coated articles.

Abstract: Aqueous, solution or emulsion, and solvent based compositions comprising a crosslinked vinyl addition polymer having methacrylaldimine crosslinking groups are useful as coatings, binders and adhesives. The polymers are prepared from a crosslinkable composition comprising (A) a vinyl addition homopolymer or copolymer of methacrolein and (B) a compound having at least two amine-function groups selected from primary amine and primary amine-generating groups. A method of use is described in which crosslinking is at ambient temperatures.

Abstract: The present invention is concerned with novel monomers containing sulfonic acid groups or salts thereof and polymers thereof which are useful for many purposes, such as antistatic agents for textiles and other shaped articles formed of hydrophilic materials. They are useful for making copolymers that are particularly valuable in coating compositions, especially in the form of aqueous latices or organic solvent solutions thereof. Examples of the monomers are of the formula ##STR1## wherein R is hydrogen or lower (C.sub.1 -C.sub.4)alkyl, such as methyl, A is an alkylene group having 2 to 10 carbon atoms, at least 2 of which extend in one chain between the oxygen atoms, andX is an aromatic nucleus or an alkyl group, substituted by a sulfonic acid group and optionally one or more groups selected from sulfonic acid, carboxylic acid, and lower alkyl, such as methyl, ethyl, propyl, or butyl.

Abstract: .beta.-Hydroxyalkylamide polymers are disclosed as self-curing by means of carboxy or anhydride functions in said polymers. The polymers are effective in solution, aqueous emulsion and powder coating formulations.

Abstract: .beta.-Hydroxyalkylamide polymers are disclosed as curable by nonpolymeric compounds having carboxy or anhydride functions. The .beta.-hydroxyalkylamide polymers are prepared either from known compounds or may be prepared by treating an ester group with an appropriately substituted amine. The polymers are useful in organic solvent solution, aqueous systems, and powder coating formulations.
