    Abstract: Print pastes and dye pastes for printing and dyeing fibrous materials based on organic dispersion of cross-linkable copolymers as binders for the pigments. The disperse copolymers, which can be used as binders without emulsions, are prepared by polymerization of (a) monomers which bear N-methylol groups or Nalkoxymethyl groups with (b) comonomers which do not contain any of the groups specified under (a), in (c) an organic liquid in which the copolymer is insoluble, and in the presence of a copolymer of comonomers of groups (a) and (b) which is soluble in (c) and acts as a polymeric emulsifier.

    Abstract: SURFACE COATINGS BASED ON A DISPERSION OF A COPOLYMER (I) WHICH CONTAINS UNITS OF (A) 50 TO 95% BY WEIGHT OF A COPOLYMERIZABLE ESTER OF A MONOOLEFINICALLY UNSATURATED CARBOXYLIC ACID HAVING THREE TO FIVE CARBON ATOMS AND AN ALCOHOL HAVING ONE TO EIGHT CARBON ATOMS; (B) 0.75 TO 25% BY WEIGHT OF AN N-METHYLOLAMIDE OF A COPOLYMERIZABLE OLEFINICALLY UNSATURATED CARBOXYLIC ACID HAVING THREE TO FIVE CARBON ATOMS WHICH HAS BEEN ETHERIFIED WITH AN ALCOHOL HAVING ONE TO EIGHT CARBON ATOMS; AND (D) 0 TO 40% BY WEIGHT OF AT LEAST ONE OTHER COPOLYMERIZABLE MONOOLEFINICALLY UNSATURATED MONOMER. COPOLYMER I IS PREPARED BY POLYMERIZING THE SAID MONOMERS IN AN ORGANIC LIQUID IN WHICH THE COPOLYMER (I) IS INSOLUBLE, IN THE PRESENCE OF A POLYMER (II) OR POLYCONDENSATES (II) OR A MIXTURE OF BOTH WHICH IS DISSOLVED IN THE ORGANIC LIQUID USING A CONVENTIONAL POLYMERIZATION INITIATOR.

    Abstract: Compositions for use as a finishing coat on plasticized polyvinyl chloride films comprise aqueous dispersions of a copolymer of: (A) 40 to 90% by weight of methyl methacrylate; (B) 1 to 20% by weight of an ester of a polymerizable a ,b -ethylenically unsaturated carboxylic or di-carboxylic acid with a polyhydric alcohol bearing a chlorine atom in a -position to a free hydroxyl group; and (C) up to 59% by weight of one or more other ethylenically unsaturated, polymerizable compounds, the sum of the percentages of (A), (B) and (C) totalling 100. Examples of (B) are chlorohydrin esters of acrylic, methacrylic, fumaric and maleic acids with polyhydric alcohols such as 3 - chloropropanediol - (1,2); (2,3) - dichlorobutanediol - (1,4); 3 - chlorobutanetriol-(1,2,4); (1,4) - dichlorobutanediol - (2,3); 3-chloro - 2 - methyl propanediol - (1,2) and 3 - chloro - 2 - chloromethylpropanediol - (1,2). Examples of (C) are N-methylol methacrylamide, styrene, a -methyl styrene, vinyl acetate, acrylic or methacrylic acid, acrylo- or methacrylonitrile and acrylic esters of alcohols having 1 to 18 carbon atoms. The polymers are obtained by polymerization of the monomers in aqueous dispersion, the dispersions having a polymer content of 25 to 60% by weight. The dispersion may also include thickening agents such as vinylpyrrolidone-vinyl propionate copolymers; precondensates of formaldehyde with urea or melamine, e.g. dimethylol propyleneurea, dimethylolethylenurea, N,N1,N11, N111 - tetramethylolglyoxaldiureine, N,N1-dimethylol - glyoxalmonoureine or N,N1-dimethylolurea etherified with methanol; wetting agents such as sodium isopropylisohexyl-naphthalene sulphonate and buffers, e.g. an aqueous solution of NaHCO3 or NH4Cl.ALSO:Finishing coats on plasticised polyvinyl chloride films are produced by applying an aqueous dispersion of a copolymer of: (A) 40 to 90% by weight of methyl methacrylate (B) 1 to 20% by weight of an ester of a polymerizable a ,b -ethylenically unsaturated carboxylic or dicarboxylic acid with a polyhydric alcohol bearing a chlorine atom in a -position to a free hydroxyl group, and (C) up to 59% by weight of one or more other ethylenically unsaturated, polymerizable compounds, the sum of the percentages (A), (B) and (C) totalling 100, and drying the coating. Examples of (B) are chlorohydrin esters of acrylic, methacrylic, fumaric and maleic acids with polyhydric alcohols such as 3-chloropropanediol-(1,2), (2,3)-dichlorobutanediol-(1,4) 3-chlorobutanetriol-(1,2,4), (1,4)-dichlorobutanediol-(2,3), 3-chloro-2-methyl propanediol-(1,2) and 3-chloro-2-chloromethylpropanediol. Examples of C are acrylic or methacrylic acid, acrylo- or methacrylonitrile, acrylic esters of alcohols having 1 to 18 carbon atoms, n-methylol methacrylamide, styrene, a -methyl styrene, vinyl acetate. Thickening agents may be added to the dispersion which may be applied as a paste by a coating knife. Examples disclose vinylpyrrolidone copolymers as thickening agents. Precondensates of formaldehyde with urea or melamine may be added to the dispersion such as aminoplasts, e.g. dimethylolpropylenurea, dimethylolethylenurea, N, N\sv, N\yF, N\yG-tetramethylol glyoxaldiureine, N, N\sv-dimethylol-glyoxalmonoureine or N, N\sv-dimethylolurea etherified with methanol. In some of the Examples the plasticized polyvinyl chloride is in the form of a coating on a substrate such as cloth and is pregelled at 120 DEG to 130 DEG C, the finishing coat then spread on and gelling completed at 170 DEG to 180 DEG C, and finally embossed. A wetting agent is present in the aqueous dispersion in some cases.

    Abstract: 1389862 Emulsions of silicon compounds BADISCHE ANILIN-& SODA-FABRIK AG 28 July 1972 [29 July 1971] 35329/72 Heading B1V [Also in Divisions C3 and Dl] Stable aqueous emulsions of organic silicon compounds are prepared by mechanically emulsifying a mixture of 2-70 wt% of an organic silicon compound with 98-30 wt% of water, in the presence of 0.1-2 wt% (based on the mixture) of a copolymer derived from 5-50 mole% of maleic anhydride, 50-95 mole % of a non-saponifiable monomer and optionally 0.5-7 mol% of a polyamine, and optionally adjusting the pH to at least 7.5. There may also be present conventional emulsifying agents, e.g. polyoxyalkylated alkylphenols and a hydrocarbon solvent for the copolymer. In Examples a trimethylsilyl-terminated polydimethylsiloxane of 5000 cS/25‹C or tetrastearyl or tetraoleyl silicate is emulsified with water in the presence of copolymers of maleic anhydride and vinyl isobutyl ether, in 50:50, 30:88 and 25:71 molar ratio, neutralized with 0, 2 or 5 molar % of hexamethylene diamine, the emulsion also optionally containing a polyoxyethylated castor oil or nonylphenol or a methylated trimethylolmelamine, and being adjusted in pH with aqueous ammonia or triethanolamine.
