Novel catalysts for the ring-opening polymerization of unsaturated alicyclic compounds
Abstract
Abstract THERE IS DISCLOSED A PROCESS FOR THE RING-OPENING POLYMERIZATION OF CERTAIN UNSATURATED ALICYCLIC COMPOUNDS WHICH COMPRISES SUBJECTING SAID UNSATUATED ALICYCLIC COMPOUNDS TO A CATALYST SYSTEM COMPRISING (A) AT LEAST ONE COMPOUND SELECTED FROM A GROUP CONSISTING OF ALKYLALUMINUM DIHALIDES, ALKYLALUMINUM SESQUIHALIDES AND ALUMINUM HALIDES, (B) AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF MOLECULAR OXYGEN, CHLORINE, BROMINE, IODINE AND CYANOGEN HALIDES, AND (C) AT LEAST ONE TRANSITION METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF TUNGSTEN AND MOLYBDENUM CARBONYL COMPLEX COMPOUNDS CORRESPONDING TO THE FORMULA M(CO)4R WHERE M IS TUNGSTEN AND MOLYBDENUM AND R IS AN UNSATURATED HYDROCARBON COMPOUND HAVING AT LEAST TWO NONCONJUGATED CARBON-TO-CARBON DOUBLE BONDS AND WHEREIN R IS ATTACHED TO THE TRANSITION METAL BY COORDINATION THROUGH TWO CARBON-TO-CARBON DOUBLE BONDS.
