Alternating copolymers of alpha-olefins and vinyl compounds and a process for manufacturing the same
Abstract
Abstract A CONJUGATED VINYL COMPOUND HAVING CARBONYL OR THIOCARBONYL GROUP AT THE CONJGATED POSITION OF THE DOUBLE BOND OF THE VINYL GROUP FORMS A COMPLEX WITH AN ORGANOALUMINUM HALIDE. THE ACRYLIC COMPOUND OF THIS KIND INCLUDES ACRYLIC ESTER, ACRYLAMIDE, ACRYLOYL HALIDE, ACRYLIC ACID, SALTS OF ACRYLIC ACID, ACROLEIN, VINYL KETONE AND THE LIKE. SAID ACRYLIC COMPOUND IS COPLYMERIZED WITH A TERMINALLY UNSATURATED HYDROCARBON, SUCH AS PROPYLENE, ISOBUTYLENE, STYRENE, ETHYLENE AND THE LIKE TO FORM A COPOLYMER, WHICH IS A 1:1 ALTERNATING COPOLYMER CONTAINING ALTERNATELY THE TWO MONOMER UNITS. THE PRESENT INVENTION HAS, FOR THE FIRST TIME, ENABLED A 1:1 ALTERNATING COPOLYMER TO BE PRODUCED FROM THE COMBINATION OF MONOMERS FROM WHICH ONLY A RADOM COPOLYMER HAS HERETO FORE BEEN PRODUCED, AND ALSO ENABLED A HIGH MOLECUALR WEIGHT POLYMER TO BE EASILY PRODUCED FROM THE COMBINATION OF MONOMERS, WHICH ARE DIFFICULT TO COPOLYMERIZE. THE PRESENT INVENTION PROVIDES SUCH ALTERNATING COPOLYMER, AND A NOVEL COPOLYMERIZATION PROCESS EMPLOYING A MONOMER COMPLEXD WITH AN ORGANOALUMINUM HALIDE.
