Abstract

A copolymer of a primary ethylenicallyunsaturated carboxylic acid amide and another ethylenically-unsaturated compound is condensed with formaldehyde and etherified with a monohydric alcohol free from aliphatic unsaturation in the presence of an etherification catalyst, the alcohol also acting as solvent. Specified amides are acrylamide, methacrylamide, alpha - ethylacrylamide, crotonamide, fumaric acid diamide and maleic acid diamide. They may be copolymerized with, for example, butadiene, isoprene, isobutylene, styrene and its alkyl derivatives, acrylic, methacrylic, alpha-ethacrylic, crotonic, maleic and fumaric acids and their esters, vinyl esters, N-substituted acrylamides and methacrylamides, vinyl and vinylidene halides, and N-vinylcarbazole, N-vinyl pyridine and N-vinyl pyrrolidone. Mixtures of more than one amide and more than one copolymerizable compound may be used. Examples of etherifying alcohols are ethanol, n-propanol, n- and iso-butanol, amyll alcohol, hexanol, octanol, 2-ethylhexanol, iso-nonyl-alcohol, decyl and lauryl alcohols, cyclohexanol, methylcyclohexanol and benzyl alcohol. They are preferably used in admixture with inert solvents such as aliphatic and aromatic hydrocarbons. The alcohol may also have been used as solvent in the initial polymerization and in the condensation with formaldehyde. Other solvents may however be used for the latter condensation, e.g. hydrocarbons, esters and ketones. Suitable etherification catalysts are those which can produce a pH of about 2.5 to 4.5, 3.g. hydrochloric, phosphoric, phthalic and formic acids, a mixture of glycerine and boric acid and salts of strong acids with weak bases. They may be neutralized after the reaction by the addition of alkali. The products may be mixed with other solvents (such as hydrocarbons), pigments, alkyl-, urea-, melamine-, phenol- and urethane resins, polyamides and cellulose derivatives, to form lacquers, films, adhesives, impregnants and coating compositions for a variety of materials. Hardening agents may be added, e.g. maleic acid, p-toluene sulphonic acid and its chloride, hydrochloric and nitric acids and ammonium nitrate. Specification 467,492 is referred to.
