    Abstract: Synthetic resinous bodies especially in sheet form, such as plates, foils, webs and non-wovens, have their chemical and thermal stabilities and their fire resistance improved by application thereto of a polyester of an aromatic dicarboxylic acid, such as terephthalic acid optionally admixed with isophthalic acid, and a halogenated dihydric phenol which may be mixed with up to an equal mole percent of a halogen-free dihydric phenol. The synthetic resinous material may be a crude pre-form wrapped in a sheet of the polyester and formed into final shape with heat and pressure and, optionally, curing. An epoxy resin or polyurethane adhesive may help bond the synthetic resinous material to the polyester sheet. The synthetic resinous body may comprise a polyamide, polycarbonate, polyvinylchloride, polystyrene or polyester.

    Abstract: THERMOSTABLE ELECTRICAL INSULATION SHEETS, FILMS, COATINGS AND IMPREGNATIONS MADE FROM POLYESTER POLYMERS OF THE GENERAL FORMULA

    -(CO-C6H4-COO-R-O)N-

    WHEREIN N IS A WHOLE NUMBER FROM 80 TO 300, PREFERABLY FROM 100 TO 255, AND R REPRESENTS A BIVALENT ORGANIC RADICAL WHICH CONTAINS TWO CHLORINATED PHENYLENE RADICALS, AND MAY CONTAIN, IF DESIRED, AN ALKYLENE GROUP, A SULFONYL GROUP OR AN OXYGEN ATOM BETWEEN THE TWO CHLORINATED PHENYLENE RADICALS. THE CHLORINATED PHENYLENE MOIETY MAY CONSTITUTE 1 TO 40 MOLE-PERCENT, OF THE POLYMER. ABOUT 20 TO 99%, AND PREFERABLY 30 TO 80%, OF THE CARBONYL ESTER GROUPS ON THE NON-CHLORINATED PHENYLENE RADICAL OF THE ABOVE FORMULA ARE IN THE META POSITION IN RELATION TO ONE ANOTHER, AND THE REST ARE IN THE PARA POSITION.
