Abstract: A water reducible resin for use in a coating composition is produced by grafting in organic solvent a thermoplastic polymer onto a thermosetting polymer that has been copolymerized with acid group-containing monomers to render the resultant polymer water soluble. Thermoplastic polymer is also grafted onto a phosphatized polyepoxide for the sake of adhesion of a coating to a substrate. A film formed from a waterborne coating composition containing the grafted polymers as a binder has both the toughness properties characteristic of a thermoplastic and the flexibility properties of a thermosetting resin.

Abstract: An oligomer of the structure: ##STR1## wherein R.sub.1 is hydrogen, lower alkyl having 1 to 5 carbon atoms or hydroxyalkyl having 1 to 5 carbon atoms; R.sub.2 and R.sub.3 are the same or different radicals selected from hydrogen, alkyl having 1 to 5 carbon atoms or one of R.sub.2 and one of R.sub.3 radicals joined together with the carbon atom to which they are attached to form cycloalkyl; R.sub.5 is hydrogen or methyl; R.sub.6 is alkyl having 1 to 6 carbon atoms, cycloalkyl of 5 to 6 carbon atoms and hydroxyalkyl of 2 to 6 carbon atoms. The oligomers can be used as reactive components with other materials containing co-reactive functional groups selected from hydroxyl, carboxylic acid, carboxylic acid anhydride and isocyanate. Reactive compositions can be formed which are useful as resinous film formers in coating applications which can be cured without the generation of formaldehyde.

Abstract: Polymers containing one or more groups of the formula: ##STR1## where R.sub.4 is alkyl having 1 to 6 carbon atoms, cycloalkyl of 5 to 6 carbon atoms and hydroxyalkyl of 2 to 6 carbon atoms; R.sub.1 is hydrogen, alkyl having 1 to 5 carbon atoms or hydroxyalkyl having 1 to 5 carbon atoms; R.sub.2 and R.sub.3 are the same or different radicals selected from hydrogen, alkyl having 1 to 5 carbon atoms or one of the R.sub.2 and one of the R.sub.3 radicals joined together with the carbon atom to which they are attached to form cycloalkyl. The polymers can be made self-curing or can be combined with a co-reactable second material containing functional groups selected from hydroxyl, carboxylic acid, carboxylic acid anhydride and isocyanate to form curable compositions. The self-curable polymers and the curable polymer compositions are useful as resinous film formers in coating compositions which can be cured without the generation of formaldehyde.

The saturated polymer is formed from a monomeric mixture of carboxylic acid or anhydride containing ethylenic unsaturation with optionally additional copolymerizable ethylenically unsaturated monomers. In a second stage, a monomeric mixture of vinyl monomers is added to the water dispersion and the resultant mixture polymerized so as to form the substantially external surfactant-free vinyl polymer emulsion product.

Abstract: Water-based coating compositions for use as internal sanitary liners for metal containers containing beer, carbonated and non-carbonated soft drinks, and fruit juices consist essentially of aqueous dispersions of amine-solubilized interpolymers, and interpolymers being formed from substituted carboxylic acid amide units; ethylenically unsaturated acid units; hardening units from monomers such as styrene, vinyl toluene or alkyl methacrylates having from 1 to 4 carbon atoms and flexibilizing units from certain alkyl acrylates or methacrylates. The interpolymers are solubilized by neutralizing the acid units of the interpolymer with monomeric amines. In order to produce a stable composition, the amount of amine utilized in neutralizing the acid groups of the interpolymer should be sufficient to produce at least 0.200 milliequivalents of salt per gram of resin solids.

The presence of the above sulfonic acids or sulfonates catalyzes the crosslinking reaction during baking and remains a part of the interpolymer.
