Abstract

Water-soluble copolymers containing recurring units of the N-methylglucamide of acrylic acid are obtained by reacting a copolymer of methyl acrylate and at least one monoethylenically unsaturated monomer with sufficient N-methyl-glucamine to convert from 10%-100% of the methyl acrylate units to amide units and thereby render the copolymer water-soluble, the reaction being carried out at a temperature in the range of 115 DEG -155 DEG C. in the presence of an inert organic solvent, e.g. dimethyl formamide, dimethyl sulphoxide or dioxane. Unsaturated monomers specified are alkyl acrylates and methacrylates, acrylic acid, acrylonitrile, styrene, chlorostyrene and alkyl styrenes, vinyl ethers and sulphides, N-vinyl pyrrolidone, piperidone and oxohexamethyleneimine and alkyl derivatives thereof, vinyl sulphones and N-vinyl alkylene-ureas. In the examples, the use is described of copolymers of methyl acrylate with methyl, ethyl and dodecyl methacrylates. When the resulting copolymer contains unreacted methyl acrylate units, these may be hydrolysed by treatment with an alkali metal or ammonium hydroxide, or reacted with a low molecular weight amine, e.g. dimethylamine, dibutylamine, N-methyl-N-propylamine, dimethylaminopropylamine or diethylaminobutylamine. The copolymers may be used as soil conditioners, whiteness retention agents for textiles and in applications to paper.
