    Abstract: In a process for the production of expandable granular thermoplastic material with a grain size of 0,2-4 mm., water containing a dispersing agent for organic liquids immiscible with water, and a solution of a thermoplastic resin in a low-boiling organic solvent which forms with water two separate phases and which also contains in solution 2-20% (based on the weight of the thermoplastic resin) of a water-insoluble expanding agent for the resin, are admixed while being kept in steady motion, the organic solvent is removed from the mixture while continuing the steady motion, and the resulting thermoplastic granules are separated from the aqueous phase. Specified thermoplastic resins are polymers of styrene, acrylic and methacrylic acid esters, vinyl chloride, vinylidene chloride, vinyl carbazole, the polycarbonate produced from butane-diol-(1,4), 2,2-di-(p-hydroxyphenyl)-propane and phosgene, a styreneacrylonitrile copolymer, and condensation products of linear polyesters or polyamides. Chlorpolystyrene may also be used: this is made, as described in Example 1, by leading chlorine into a solution of polystyrene in methylene chloride and expelling the resulting hydrogen chloride by a current of nitrogen. The resulting solution may be used directly as one component of the mixture by adjusting its pH to 8 by addition of dry ammonia, and adding an expanding agent thereto. Specified solvents are methylene chloride, ethylene chloride, carbon tetrachloride, 1,1,2-trichlorethane, benzene, ethyl acetate, diisopropyl ether and tetrahydrofuran. Specified expanding agents are the volatile liquid type, such as petroleum ether, pentane, cyclopentane, hexane, cyclohexane, heptane, diethyl ether and carbon tetrachloride, and the decomposable type such as azoisobutyronitrile, diazoaminobenzene and benzene sulphonic acid hydrazide. The solution of thermoplastic resin may also contain fillers, pigments, dyestuffs, softeners, flame-preventing additives and insecticides. In one example (2), glycol diglycidyl ether is added as a stabilizer to a chlorpolystyrene solution. Specified dispersing agents are polyvinyl pyrrolidone, a copolymer of vinyl pyrrolidone and methyl acrylate, gelatin, casein, polyvinyl alcohol, polyacrylic acid (or salts thereof), kaolin, talc, precipitated magnesium hydroxide or barium sulphate, and alkali salts of alkyl sulphonic acids, alkyl naphthalene sulphonic acids and long-chain aliphatic carboxylic acids. The solvent may be removed from the mixture either during or after mixing, e.g. by leading an inert gas such as nitrogen or carbon dioxide therethrough, or by distilling off under reduced pressure. The granules may be separated from the aqueous phase by filtering or centrifuging, and may be expanded to form a closed-cell body by heating above the softening-point of the resin and above the temperature at which the expanding agent acts.ALSO:In a process for the production of expandable granular thermoplastic material with a grain size of 0,2-4 mm., water containing a dispersing agent for organic liquids immiscible with water, and a solution of a thermoplastic resin in a low-boiling organic solvent which forms with water two separate phases and which also contains in solution 2-20% (based on the weight of the thermoplastic resin) of a water-insoluble expanding agent for the resin, are admixed while being kept in steady motion, the organic solvent is removed from the mixture while continuing the steady motion, and the resulting thermoplastic granules are separated from the aqueous phase.

The solvent may be removed from the mixture either during or after mixing, e.g. by leading an inert gas such as nitrogen or carbon dioxide therethrough, or by distilling off under reduced pressure. The granules may be separated from the aqueous phase by filtering or centrifuging, and may be expanded to form a closed-cell body by heating above the softening-point of the resin and above the temperature at which the expanding agent acts.

    Abstract: The invention comprises a film-forming copolymer of (a) at least one vinyl compound, (b) at least one maleic acid half ester and (c) at least one maleic acid half-amide, the amount of (a) being equal to 50-70 mol per cent and the sum of (b) and (c) being equal to 30-50 mol. per cent. The copolymer may be obtained by copolymerizing a vinyl compound with a mixture of at least one maleic acid half-ester and at least one maleic acid half-amide, or by copolymerizing a vinyl compound with maleic anhydride and then reacting the copolymer with at least one alcohol and at least one amine. The vinyl compounds may be styrene (which is the compound used in all the specific examples), alpha-methylstyrene, vinyl toluene, halogenated styrenes, vinyl acetate, vinyl propionate, vinyl chloride, vinyl sulphonic acid, vinyl phosphoric acid, vinyl ethyl ether, vinyl butyl ether, vinyl cyclohexyl ether, acrylic acid esters of alkyl or cycloalkyl alcohols containing 1-8 carbon atoms in the alcohol component, or acrylonitrile. The alcohols may have up to 15 carbon atoms and may be methanol, ethanol, propanol, butanol, isobutanol, ethylhexanol, cyclohexanol, or benzyl alcohol. The amines may have up to 16 carbon atoms and may be dibutylamine, di-isobutylamine, diethylamine, dipropylamine, cyclic hexamethylene imine, pyrrolidine or piperidine. Copolymerization may be effected in bulk, in suspension, or in solution in benzene, toluene, xylene or ethanol. As polymerization catalysts there may be used azoisobutyronitrile, hydrogen peroxide, benzoyl peroxide or alkali persulphates. The resulting lacquer resins are compatible with shellac or manila resins.
