| titleOfInvention | Coloured crosslinkable and crosslinked copolymers |
| abstract | Coloured cross-linked or cross-linkable copolymers are obtained by copolymerizing at least one olefinic monomer dyestuff, containing, in addition to the unsaturated at least one olefinic monomer polymerizable group, a group capable of condensation or addition, and, if desired, at least one further copolymerizable monomer, and then, if desired, cross-linking the resulting copolymers by way of the groups capable of condensation or addition. The dyestuff monomers may be of the azo, anthraquinone, phthalocyanine, triarylmethane, phenazine, or oxazine type, such dyestuffs being described in Specifications 779,781, 830,876, 858,183, 875,946 and 879,071. The examples describe the following processes: (1) emulsion copolymerizing butyl acrylate, N-methylol methacrylamide and an unsaturated azo dyestuff to yield a copolymer which cross-links on drying; (2) emulsion copolymerizing acrylonitrile, butyl acrylate, N-methyldimethacrylamide and an unsaturated azo dyestuff; (3) as in (2) but using an unsaturated anthraquinone dyestuff; (4) emulsion copolymerizing styrene, methylolacrylamide, butyl acrylate, N-methylolacryloylurea and acryloylaminobenzene, and cross-linking the resulting polymer by heating in the presence of ammonium nitrate; (5) emulsion polymerizing ethyl acrylate, vinyl propionate, N-methylolmethacrylamide, N-methylol maleimide and an unsaturated azo dyestuff and cross-linking the resulting copolymer by heating; (6) emulsion copolymerizing butyl acrylate, acrylonitrile, butane-diol monoacrylate and an unsaturated azo dyestuff, and cross-linking the resulting copolymer with hexamethylene diisocyanate; (7) emulsion copolymerizing butyl acrylate, methacrylamide and an unsaturated azo dyestuff and cross-linking the product by heating with dimethylol urea; (8) cross-linking the copolymer of (7) by heating with N,N1-dimethylolbutane-(1,4)-diurethane; (9) emulsion copolymerizing butyl acrylate, acrylonitrile, acrylic acid and an unsaturated azo dyestuff, neutralising the carboxyl groups in the product with ammonia, and heating it with a polyepoxide derived from pentaerythritol and epichlorohydrin; (10) emulsion copolymerizing butyl acrylate, N-methylolacrylamide and an unsaturated azo dyestuff, mixing the resulting dispersion with an acrylamide/methacrylamide copolymer, sawdust and a mixture of N,-N1 dimethylolurea monomethyl and dimethyl ethers, drying the composition and moulding at 150 DEG C.; (11) emulsion copolymerizing butyl and ethyl acrylates, methyl methacrylate methacrylamide and an azo dyestuff containing vinyl ether groups, adding a mixture of N,N1-dimethylol urea monomethyl and dimethyl ethers and heating in the presence of ammonium nitrate; (12) emulsion copolymerizing butyl acrylate, N-methylol methacrylamide, a triazine derivative of acrylamide and an unsaturated azo dyestuff, mixing the dispersion with N,N1-dimethylolbutane-(1, 4)-diurethane and ammonium nitrate and subjecting the mixture to heat; (13) emulsion copolymerizing butyl acrylate, acrylamide, vinyl chloride and an unsaturated azo dyestuff, mixing the dispersion with N,N1-dimethylol urea and cross-linking at 130 DEG C.; (14) solution copolymerizing butyl acrylate, acrylamide, methyl methacrylate, butanediol monoacrylate and an azo dyestuff containing vinyl ether groups and cross-linking the product with hexamethylene diisocyanate; (15) solution copolymerizing methyl methacrylate butyl acrylate, acrolein and an unsaturated azo dyestuff, and cross-linking the product with the glycol ester of bisacetoacetic acid; (16) solution copolymerizing butyl acrylate, vinyl propionate, methacrylamide, N-methylol methacrylamide and an unsaturated anthraquinone dyestuff, and heating the product after the addition thereto of phosphoric acid; (17) as in (3) but with the use of tetramethylolacetylene diurea tetrabutyl ether at the cross-linking stage and with the addition of wood pulp to the curable mixture; (18) bulk copolymerizing methyl methacrylate, butanediol monoacrylate and an unsaturated azo dyestuff in the presence of dibutylphthalate until the product is syrupy, discontinuing polymerization and then heating the product with hexamethylene diisocyanate; (19) solution copolymerizing vinyl pyrrolidone, methyl methacrylate, butyl acrylate, N-methylol methacrylamide and a copper phthalocyanine dyestuff containing sulphonic groups which have been reacted with N-acryloyl - p - phenylene diamene, and heating the product with tetramethylolacetylenediure tetrabutyl ether; and (20) solution copolymerizing acrylamide ethyl acrylate, N-methylol methacrylamide and an unsaturated azo dyestuff, and heating the product with tetramethylolacetylene diurea.ALSO:Surfaces of paper, wood and metal are coated with coloured copolymers obtained from olefinic monomer dyestuffs, monomers containing cross-linkable groups, and, if desired, other copolymerizable monomers. In examples: (2) wood and paper are coated with an aqueous dispersion of a copolymer of butyl acrylate, N-methylol methacrylamide and an unsaturated azo dyestuff, and the coating is dried at 180 DEG C.; (13) paper and a metal plate are coated with an aqueous dispersion containing a copolymer of butyl acrylate, vinyl chloride, acrylamide and an unsaturated azo dyestuff, N,N1-dimethylolurea and ammonium nitrate, the coating is dried at room temperature and cross-linked at 130 DEG C.; (15) a toluene-ethanol solution containing a copolymer of methyl methacrylate, acrolein and an unsaturated azo dyestuff, the glycol ester of bisacetoacetic acid, phosphoric acid and piperidine is brushed or sprayed on to bleached wood, and the coating is dried at 80-90 DEG C.; and (19) a tolueneethanol solution containing a copolymer of vinyl pyrrolidone, methyl methacrylate, butyl acrylate, N-methylol methacrylamide and a copper phthalocyanine dyestuff containing sulphonic groups which have been reacted with N-acryloyl-p-phenylene diamine, tetramethylolacetylenediurea tetrabutyl ether and glacial acetic acid is brushed on to wood or paper and dried at 140 DEG C. Specifications 779,781, 830,876, 858,183, 875,946 and 879,071 are referred to. |
