Abstract

New polycarbonate resins contain the residues of a bis-(hydroxyphenyl) phenyl methane which contains at least one cyclizing divalvent radical which forms a non-aromatic ring by interconnecting a carbon atom of one of the phenyl group with the methane carbon atom or with a carbon atom of another phenyl group, the residues being in a proportion to provide at least 50% by weight of the resin. Prepared dihydroxy compound are phenolphthalein, phenolsulphonephthalein, fluorescein and phthalidein and these substances nuclear substituted by alkyl, cyclophenyl, chloro, bromo, iodo and nitro radical. The polycarbonates may also contain the residues of other dihydroxy compound, e.g. ethylene-, alpha-propylene-, hexamethylene-, diethylenetriethylene- or dipropyleneglycols; 1:4-cyclohexanediol, 1:3-cyclopentanediol, hydroquinone, 4:41dihydroxydiphenyl, 4:41-isopropylidenediphenol, 4:41-cyclohexylidenediphenol, 4:41-methylenediphenol, 4:41-isopropylidene-o-cresol, 4:41-isopropylidene bis (2-phenylphenol), 4:41-isopropylidene bis (2-tertbutylphenol), 4:41-or 2,41-sulphonyldiphenol and 4:41-oxydiphenol. The polymers are made by reacting the bis-(hydroxyphenyl) phenyl methane derivatives with phosgene or a bischloroformate, preferably in an aqueous alkaline medium containing a solvent (e.g. methylene chloride) and a catalyst (e.g. a quaternary ammonium compound). Uses: fibres, films, mouldings, castings.
