Styrene polymerization with aryltitanium trialkylate catalysts

Claim 1

METHOD FOR POLYMERIZING STYRENE WHICH COMPRISES ADMIXING SAID STYRENE WITH AN ARYLTITANIUM TRIALKYLATE COMPOUND, THE AMOUNT OF SAID STYRENE IN SAID MIXTURE BEING FROM 1 POUND TO 100 POUNDS FOR EACH GRAM MOLE OF THE TITANIUM COMPOUND, THE TEMPERATURE OF SAID MIXTURE BEING FROM 0*C. TO 150*C., SAID ARYLTITANIUM TRIALKYLATE BEING AN ESTER OF TETRAVLENT TITANIUM WHEREIN ONE OF THE FOUR VALENCIES OF SAID TETRAVALENT TITANIUM IS SATISFIED BY AN ARYL GROUP THROUGH A DIRECT CARBON-TITANIUM BOND, AND THE REMAINING THREE VALENCIES OF SAID TITANIUM ARE SATISFIED BY ALKOXY GROUPS THROUGH OXYGEN-TITANIUM BONDS, SAID ALKOXY CONTAINING FROM 1 TO 16 CARBON ATOMS, SAID ARYL GROUP BEING SELECTED FROM THE GROUP CONSISTING OF PHENYL, SUBSTITUTED PHENYL, NAPHTHYL AND SUBSTITUTED NAPHTHYL, THE SUBSTITUENT IN SAID SUBSTITUTED PHENYL AND SUBSTITUTED NAPHTHYL ARE SELECTED FROM THE GROUP CONSISTING OF LOWER ALKOXY, LOWER ALKYL AND PHENYL, SAID LOWER ALKOXY AND SAID LOWER ALKYL CONTAINING FROM 1 TO 6 CARBON ATOMS IN THE HYDROCARBON CHAIN, AND SEPARATING THEREFROM THE POLYSTYRENE FORMED.
