Patent GB-779291-A (GB)
Title: Process for the production of polyesters of high molecular weight
IPC: C08G63/08
Filed: 1955-01-28
Abstract: Polyesters are made by polymerizing optically active lactic acid or a polylactide-forming derivative thereof (e.g. lactide or an ester of lactic acid with a monohydric alcohol) which contains not more than 20 per cent of the oppositely rotating component. The resulting polylactides are optically active and have a higher molecular weight (e.g. greater than 5000) and a higher melting point (e.g. 90-140 DEG C. or higher) than previously known polylactides.  Polymerization is effected at 100-250 DEG  C., preferably in the absence of oxygen and may be effected in presence of a solvent or entraining agent, e.g. benzene or toluene.  When polymerizing lactic acid, catalysts which may be used are sodium bicarbonate, magnesium oxide, zinc oxide, lead oxide, zinc, lead, lead acetate, p-toluene sulphonic acid, sulphuric acid or boric acid.  When polymerizing lactide, catalysts which may be used are metals of the 2nd sub-group or the 4th main group of the periodic system or their oxides, hydroxides, acetates, lactates or carbonates; also magnesium, magnesium oxide, titanium dioxide, lanthanum oxide, antimony oxide, bismuth acetate, uranyl acetate, manganese lactate, p-toluene sulphonic acid, halides of metals of the 2nd sub-group of the periodic system or bicarbonates of metals of the 1st main group of the periodic system.  When polymerizing lactides, small amounts of free acids (e.g. lactic acid) or trivalent or higher valent metals (e.g. aluminium, chromium or manganese) or their salts (e.g. aluminium lactate) may be added in addition to the catalyst (e.g. lead oxide).  Polymerization of the lactic acid or polylactide-forming derivative may also be effected in presence of other polyester forming components (e.g. glycollic acid, glycollide or adipic acid and ethylene glycol) or chain-breaking agents (e.g. benzoic acid, cyclohexylamine or glycerine).  The crude polylactide may be purified or separated from low molecular weight material by an extraction method or by dissolving it in a solvent, e.g. chloroform and precipitating the pure polylactide by adding cold methanol.  Some of the polylactides are soluble in chloroform, methylene chloride, acetone, toluene or benzene. They may be used in the manufacture of coating materials, moulded articles and foils and may be modified with drying oils, furfural or trivalent or higher-valent metal salts. Specification 755,447 is referred to.

Abstract: 555,949. Photographic emulsions. KODAK, Ltd., TEAL, E. F., and DAVEY, E. P. March 10, 1942, No. 3172. [Class 98 (ii)] A finished (i.e. washed and digested) gelatinosilver halide emulsion is made in dry or substantially dry form by taking a finished aqueous gelatino-silver halide emulsion and while in the bulk liquid state thoroughly mixing it with a water-extracting volatile liquid (e.g. alcohol or acetone), allowing the precipitate to settle, separating it, and then drying it by causing the volatile liquid in it to evaporate. The precipitate may be freed from most of its liquid by squeezing or passing through a mangle, and then dried on a tray in a current of air or in a drying cupboard. The dry powdery emulsion is re-dispersed in warm water before coating. In example 1, a finished silver bromide process emulsion is melted, brought to 30‹ C., and poured into methylated spirit at 5‹ C. After stirring and allowing to stand, the supernatant liquid is poured off, and the precipitate mangled through wooden rollers and allowed to dry in a current of air. When required for coating, the emulsion may be allowed to swell in cold water before raising the temperature to 35‹ C. for dispersing. Saponin and chrome alum may be added at this stage. In example 2, a melted silver bromide process emulsion at 30‹ C. is poured in industrial spirit containing potassium bromide at 5‹ C. and after stirring and allowing to stand, the supernatant liquid is poured off and the precipitate mangled. The emulsion is finally dried in a current of air. Instead of adding soluble halide to the waterextracting liquid, an extra quantity may be added initially to the original emulsion. Specification 22426/10, [Class 98 (ii)], is referred to.
