    Abstract: 1,157,577. Polyester moulding materials. BADISCHE ANILIN- & SODA-FABRIK A.G. 18 Nov., 1966 [20 Nov., 1965], No. 51763/66. Headings C3P and C3R. Polyester mouldings are produced by curing polyester moulding materials containing a mixture of (1) 20 to 90 parts by weight of at least one ethylenically unsaturated copolymerizable polyester which incorporates, in ester combination (a) 20 to 45 mole per cent of radicals of α-ethylenically unsaturated dibasic carboxylic acids, (b) 20 to 45 mole per cent of radicals of dihydric alcohols, (c) 10 to 60 mole per cent of radicals of hydroxycarboxylic acids and (d) 0 to 20 mole per cent of radicals of other carboxylic acid and/or alcoholic compounds, (2) 10 to 80 parts by weight of at least one ethylenically unsaturated copolymerizable monomer and (3) 0À001 to 1 part by weight of a conventional polymerization inhibitor in the presence of a conventional polymerization initiator, wherein polyester moulding materials are used in whose polyesters (1) the radicals of the hydroxycarboxylic acids (c) consist to the extent of at least 50% by weight, with reference to the total weight of radicals (c), of radicals of α,α-dimethyl-#- hydroxypropionic acid. In the examples polyesters derived from maleic anhydride, butanediol-1,3 or 2,2-dimethylpropanediol-1,3 and α,α- dimethyl-#-hydroxy propionic acid are used and styrene is employed as the comonomer, hydroquinone as the inhibitor and cyclohexanone peroxide and cobalt naphthenate as the initiators.

    Abstract: Water-soluble binders comprise (1) 40 to 90% by weight of a water-soluble copolymer and (2) 10 to 60% by weight of water-soluble phenoplasts and/or aminoplasts, said percentages relating to the total weight of (1) and (2), and said copolymer being a copolymer of (a) 35 to 64 parts by weight of acrylamide and/or methacrylamide, (b) 35 to 64 parts by weight of one or more esters of acrylic or methacrylic acid with saturated monohydric alcohols containing 1 to 20 carbon atoms, (c) 1 to 15 parts by weight of one or more monoesters of acrylic or methacrylic acid with saturated polyhydric alcohols, and optionally (d) 0,01 to 10 parts by weight of other copolymerizable monomers, the sum of the parts by weight of components (a) to (c) amounting to 100. Specified esters (b) are those of methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol and t. butanol. The ester (c) may be of ethanediol, propanediol-1,2, propanediol-1,3, butanediol-1,2, pentanediol-1,2, hexanediol-1,2, glycerol, 1,1,1-trimethylolpropane and pentaerythritol. The monomers (d) may be unsaturated carboxylic acids, or esters, nitriles, amides or salts thereof; vinyl esters; vinyl aromatic hydrocarbons; vinyl and vinylidene halides; vinyl lactams; vinyl amines; vinyl sulphamides and vinyl sulphones. The phenoplast may be a condensate of phenol or cresol with formaldehyde. The aminoplast may be a condensate of formaldehyde with urea, thiourea, melamine, ammeline, guanidine, dicyandiamide, glyoxalureides or ethylene urea. The binders may be dissolved in water, optionally with the addition of water-miscible organic solvents, e.g. alcohols, ethers or ketones; dyes and pigments; and levelling aids such as glycol ethers, acetals, glycols, dimethyl formamide, sulphones and sulphoxides. Examples describe the preparation of copolymers of (I) acrylamide, ethyl acrylate, t-butyl acrylate and butanediol-1,4-monoacrylate and (II) acrylamide, methacrylamide, ethyl acrylate, 2-ethylhexyl methacrylate and butanediol-1,4-monoacrylate by polymerization in n-butanol in the presence of benzoyl peroxide and sodium hydroxymethanesulphinate; and the formation of binders by dissolving these copolymers in aqueous solutions of phenolformaldehyde condensate and tetramethylolglyoxaldiureine. The compositions may be used for coating wood, metal and plastics; impregnating fabrics and paper; and laminating; and may be cured by heating, optionally in the presence of acid reacting substances such as carboxylic acids and ammonium nitrate or chloride.

    Abstract: Cured and cross-linked polyolefines are produced by intensely kneading at 60 DEG -350 DEG C. at least one polyolefine and up to 50% of at least one ethylenically unsaturated polyester together with at least one free radical forming catalyst. Up to 50% of the polyester may be replaced by at least one ethylenically unsaturated monomer having a 1.p. above 60 DEG C. The polyolefines are prepared by high or low pressure polymerization of C2-4 olefines, e.g. ethylene, propylene, butylene-1, butylene-2 or iso-butylene. The polyesters are prepared from polyols with a ,b -unsaturated polybasic carboxylic acids and have a molecular weight above 500, e.g. up to 6000. The acids may be maleic, fumaric, dichloromaleic, itaconic, citraconic and mesaconic. The polyesters may be prepared using polybasic saturated organic carboxylic acids with C4-17, e.g. dicarboxylic such as adipic, phthalic, isophthalic, endomethylenehexachlorotetrahydrophthalic, succinic, glutaric, heptadecane-dicarboxylic, terephthalic, tetrachlorophthalic, tetrabromophthalic or pyromellitic. The The polyols may contain 2-6 OH groups, e.g. ethylene- or di- or tri-ethylene glycol, propylene glycol, butanediol-1,4 and -1,3;neopentyl glycol, endomethylenehexachlorodihydrolmet hyxycyclohexane; 2,2-bis-[p-(b -hydroxyethoxy)-phenyl]-propane; glycerol, pentaerythritol, tetramethylolcyclohexanol, sorbitol, mannitol and 2-butyne-1,4-diol. Up to 10 mole per cent acid or polybl excess may be used in the production of the polyesters, and up to 10 mole per cent of the polybasic acid may be replaced by a monocarboxylic acid; some of the polyols may be replaced by monohydric alcohols. The polyesters may contain some isocyanate. The ethylenically unsaturated monomers may be monovinylaromatic, e.g. styrene and alkyl substituted styrenes and vinyl toluenes; a ,b -unsaturated mono- and di-carboxylic acids and their ester,, amides, anhydrides and nitriles; vinyl esters and ethers; and heterocyclic compounds, e.g. vinyl pyrrolidone or carbazole. The catalyst, e.g. 0,05-10%, may be organic compounds which form radicals at 60 DEG -350 DEG C., e.g. peroxides, peroxy-esters, a perbenzoate, hydroperoxides and nitriles. Kneading may be carried out with calenders, kneading machines and refiners, screw extruders and disc kneaders. The components may first be premixed, e.g. in a propeller mixer, or fed directly to the kneaders and the process may be batch or continuous. Additives, e.g. pigments, fillers, dyes, stabilizers and hardening accelerators may be used. The product may be processed, e.g. by injection moulding or deep-drawing and formed into, e.g. films, sheets, articles or cable covering.
