Substituted norbornene compounds and their applications in thermoplastic polymer compositions

Abstract

Abstract NOVEL COMPOSITIONS OF MATTER HAVING THE FOLLOWING STRUCTURAL FORMULA: 1,2,3,4-TETRA(X-),5-Z,5-(NC-),7-Y,7-Y''-2-NORBORNENE WHEREIN EACH X IS SELECTED FROM THE GROUP CHLORINE, FLUORINE AND BROMINE: Y AND Y'' ARE EACH SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN AND LOWER (1-4C) ALKYL, ALKOXY AND HALOGEN-SUBSTITUTED ALKYL AND ALKOXY RADICALS; AND Z IS SELECTED FROM THE GROUP XONSISTING OF HALOGEN, (1-4C) ALKOXY, NITRILE, THIOCYANATE, ISOCYANATE, ISOTHIOCYANATE AND PHOSPHONO GROUPS OF THE FORMULA: -P(=O)(-R'')-R WHEREIN EACH X IS CLORINE, FLUORINE OR BROMINE AND Y AND Y'' ARE EACH SELECTED FROM THE GROUP CONSISTING OF HYDROGEN: HALOGEN, PREFERABLY CHLORINE BROMINE OR FLUORINE; LOWER (1-4C) ALKYL, ALKOXY AND HALOGEN-SUBSTITUTED ALKYL ALKOXY RADICALS. 1,2,3,4-TETRA(X-),5-Y,5-Y''-CYCLOPENTADIENE WHEREIN Z IS DEFINED AS IN FORMULA I WITH HALOGENATED CYCLOPENTADIENE OF THE FORMULA: CH3-C(-Z)-CN WHEREIN R AND R'' ARE EACH SELECTED FROM THE GROUP CONSISTING OF LOWER (1-4C) ALKYL, ALKENYL, SUBSTITUTED ALKYL, ALKOXY, ALKENOXY AND SUBSTITUTED ALKOXY GROUPS. THE COMPOSITIONS OF FORMULA I ABOVE ARE HALOGEN AND PHOSPHORUS DERIVATIVES OF CYANONORBORNENE. THESE COMPOSITIONS ARE USEFUL ADDITIVES IN THERMOPLASTIC COMPOSITIONS AND LEND FLAME RETARDANT CHARACTERISTICS THERETO. THE COMPOSITION MAY BE PREPARED BY REACTING EQUIMOLAR AMOUNTS OF SUBSTITUTED ACRYLONTRILE OF THE FORMULA:
