Abstract

1522434 Flame retardant polycarbonate compositions GENERAL ELECTRIC CO 28 Oct 1976 [29 Oct 1975] 44937/76 Addition to 1495970 Heading C3R A non-opaque flame retardant composition comprises a polycarbonate and from 0À001 to 2À0% by weight, based on the polycarbonate, of an alkali metal or alkaline earth metal salt of a monomeric or polymeric aromatic sulphonic acid that contains a sulphone group bonded to an aromatic ring, the polycarbonate and the salt each having a refractive index of from 1À54 to 1À65. Many salts are specified, e.g. potassium salt of diphenyl sulphone-3-sulphonic acid.
