Resinous compositions and methods of preparing the same

Claim 1

THE METHOD OF PREPARING A RESINOUS POLYESTER WHICH COMPRISES PARTIALLY ESTERIFYING A POLYMERIC ALLYL ALCOHOL WITH A MONOCARBOXYLIC ACID SELECTED FROM THE CLASS CONSISTING OF NUCLEARYL HALOGENATED BENZOIC ACIDS, AND MONO-, DIAND TRIHALOGENOALKYL BENZOIC ACIDS, THE CARBOXYL GROUP OF THE SAID MONOCARBOXYLIC ACID BEING THE ONLY SUBSTITUENT THEREOF WHICH IS REACTIVE IN AN ESTERIFICATION REACTION, SAID PARTIAL ESTERIFICATION BEING EFFECTED AT A TEMPERATURE WITHIN THE RANGE OF 150* C. TO 250* C., AND ESTERIFYING THE RESULTING PARTIAL ESTERIFICATION PRODUCT WITH A MEMBER OF THE CLASS CONSISTING OF TETRAFLUOROSUCCINIC ACID, TETRAFLUOROSUCCINIC ANHYDRIDE AND MIXTURES THEREOF, THIS LAST ESTERIFICATION REACTION LIKEWISE BEING EFFECTED AT A TEMPERATURE WITHIN THE RANGE OF 150* C. TO 250* C., AND THE AMOUNT OF SAID TETRAFLUOROSUCCINIC SUBSTANCE BEING AT LEAST 25 MOL PER CENT OF THE TOTAL AMOUNT OF THE SAID MONOCARBOXYLIC AND TETRAFLUOROSUCCINIC ACID SUBSTANCES EMPLOYED.

Claim 2

THE METHOD OF PREPARING A RESINOUS POLYESTER WHICH COMPRISES PARTIALLY ESTERIFYING A POLYMERIC ALLYL ALCOHOL WITH A MONOCARBOXYLIC ACID SELECTED FROM THE CLASS CONSISTING OF NUCLEARYL HALOGENATED BENZOIC ACIDS, AND MONO-, DIAND TRIHALOGENOALKYL BENZOIC ACIDS, THE CARBOXYL GROUP OF THE SAID MONOCARBOXYLIC ACID BEING THE ONLY SUBSTITUENT THEREOF WHICH IS REACTIVE IN AN ESTERIFICATION REACTION, SAID PARTIAL ESTERIFICATION BEING EFFECTED AT A TEMPERATURE WITHIN THE RANGE OF 150* C. TO 250* C., AND ESTERIFYING THE RESULTING PARTIAL ESTERIFICATION PRODUCT WITH A MEMBER OF THE CLASS CONSISTING OF TETRAFLUOROSUCCINIC ACID, TETRAFLUOROSUCCINIC ANHYDRIDE AND MIXTURES THEREOF, THIS LAST ESTERIFICATION REACTION LIKEWISE BEING EFFECTED AT A TEMPERATURE WITHIN THE RANGE OF 150* C. TO 250* C., AND THE AMOUNT OF SAID TETRAFLUOROSUCCINIC SUBSTANCE BEING AT LEAST 25 MOL PER CENT OF THE TOTAL AMOUNT OF THE SAID MONOCARBOXYLIC AND TETRAFLUOROSUCCINIC ACID SUBSTANCES EMPLOYED.
