Polymers of hydrocarbon substituted 1,5-cyclooctadienes and methods for their polymerization

Abstract

Abstract THERE IS DISCLOSED A METHOD FOR THE RING OPENING POLYMERIZATION OF HYDROCARBON SUBSTITUTED CYCLOOCTADIENES OF THE FORMULA 1-R''-CYCLOOCTA-1,4-DIENE AND 1,2-DI-R''-CYCLOOCTA-1,4-DI- ENE WHEREIN R'' IS A METHYL, ETHYL, PROPYL OR BUTYL RADICAL, ARE ALSO DISCLOSED. (-CH2-CH=CH-CH2-CH2-C(-R'')=C(-R'')-CH2-) OR THE FORMULA (-CH2-CH=CH-CH2-CH2-CH=C(-R'')-CH2-) OR THE FORMULA (-CH2-CH=CH-CH2-CH2-C(-R'')=CH-CH2-) WHEREIN R'' IS AN ALKYL, ARYL, ARALKYL, ALKARYL, CYCLOALKYL OR BICYCLOALKYL RADICAL WHICH COMPRISES POLYMERIZING THESE HYDROCARBON SUBSTITUTED 1,5-CYCLOOCTADIENES IN THE PRESENCE OF A CATALYST SYSTEM COMPRISING (A) AT LEAST ONE ORGANOMETALLIC COMPOUND WHEREIN THE METAL IS SELECTED FROM THE GROUP CONSISTING OF IA, IIA, IIB AND IIIA OF THE PERIODIC TABLE OF ELEMENTS, (B) AT LEAST ONE TRANSITION METAL SALT SELECTED FROM THE GROUP CONSISTING OF TUNGSTEN AND MOLYBDENUM HALIDES AND (C) AT LEAST ONE COMPOUND OF THE GENERAL FORMULA R-Y-H WHEREIN Y IS OXYGEN; H IS HYDROGEN AND R IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF (1) HYDROGEN, (2) ALKYL, (3) ARYL, (4) ARYLALKYL, (5) ALKARYL, (6) ALKENYL, AND (7) RADICALS OF (2) THROUGH (6) WHEREIN AT LEAST ONE HYDROGEN OF THE RADICAL R MAY BE SUBSTITUTED BY AT LEAST ONE HYDROXYL OH GROUP. POLYMERS CONSISTING OF REPEATING UNITS HAVING THE FORMULA
