Abstract

Regular copolycarbonates are made by reacting a bis-chlorocarbonic acid ester of a diol with a dihydric phenol in aqueous alkaline medium, preferably sodium or potassium hydroxide solution. Specified diols are ethylene glycol, 1,4-butane diol, 1,6-hexane diol, 2,5-hexane diol, 1,8-octane diol, hexahydrohydroquinone, dimethylolcyclohexane, p.p1-dimethylol dicyclohexyl, p.p1-dimethyllol dicyclohexyl-sulphide, -sulphone or -ether, terphthalic alcohol, p.p.1 -dimethyloldiphenyl, p.p1-dimethyloldiphenylmethane,-propane, -sulphide, -sulphone orether, di-(hydroxyethoxy)-diphenylmethane, bis(hydroxyethyl-4-oxyphenyl)-dimethyl methane, 1,4-hexene-diol, butine-diol and hexadi-inediol. Specified dihydric phenols are hydroquinone, resorcinol, pyrocatechol, 4,41-dihydroxdiphenyl sulphone, (4,41-dihydroxydiphenyl)-methane, 1,1-(4,41-dihydroxydiphenyl)-cyclohexane, 3,4-(4,41-dihydroxydiphenyl-hexane, 2,2-(4,41-dihydroxydiphenyl)-propane, 1,1-(4,4-dihydroxydiphenyl)-1-phenylethane, 2,2-(2,21-dihydroxy4.41-ditertiary butyldiphenyl)-propane and 1,1-(4,41-dihydroxy-3,31-dimethyloldiphenyl) -cyclohexane. The reaction may be effected in the presence of an inert organic liquid which dissolves the polycarbonate e.g. hexane, octane, petroleum ether, gasoline, benzene, toluene, tylene, cyclohexane, methylene chloride, ethylene chloride, tetrachloroethene, chloroform dichlorobutane or chlorobenzene. Catalyst for the reaction are tertiary amines and quarternary ammonium salts. The polycarbonates are suitable for the manufacture of foils, films and threads. Examples describe the manufacture of poly-carbonates from (1) bis(4-hydroxyphenyl)-dimethylmethane and the bischlorocarbonate of 1,4-butane diol (2) hydroquinone and the bis-chlorocarbonate of 1,6-hexane diol; (4), (5), (7) and (8) (4,41-dihydroxydiphenyl)-dimethylmethane and the bis-chlorocarbonates of 1,6-hexane diol, di-hydroxyethylated (4,41-dihydroxydiphenyl)-dimethyl methane, butene-diol or cyclohexanediol-1,4; (6) (4,41-dihydroxydiphenyl)-methane, 4,41-dihydroxydiphenylsulphone and the bischlorocarbonate of 1,4-butane diol. Specifications 772,627, 808,485, 808,486 and 808,487 are referred to.
