Vanadium organophosphates
Abstract
Abstract VANADIUM ORGANOPHOSPHATES REPRESENTED BY THE FORMULA: (R-O)2-P(=O)-O-V(=O)-O-P(=O)-(O-R)2 AND POLYMERS THEREOF REPRESENTED BY THE FORMULA: (-(R-O-)P(-O-R)<(-O-V(=O)-O-P(-O-R)2-P(-O-)-O-))X WHEREIN X IS 2 TO 6, R IS AN ALKYL OR AN ALKYL ETHER HAVING 1 TO 16 CARBON ATOMS OR AN ARYL HAVING UP TO 16 ATOMS, OR MIXTURES THEREOF, CAN BE PREPARED BY A REACTION BETWEEN A VANADIUM OXIDE, OXYHALIDE, OR HALIDE OR AN ALKYL VANADATE AND A TRIALKYL, TRIALKYL ETHER OR A TIRARYL PHOSPHATE. A MIXTURE OF THE VANADIUM ORGANOPHOSPHATE AND AN ORGANOALUMINUM HALIDE FORMS AN ACTIVE VANADIUM COORDINATION CATALYST. THIS CATALYST IS ESPECIALLY USEFUL IN THE PRODUCTION OF "EP" AND "EPDM" RUBBER. A PARTICULARLY EFFECTIVE VANDAIUM COORDINATION CATALYST COMPRISES VANADIUM (IV) OXYBIS (DIETHYL PHOSPHATE) AND AN ORGANOALUMINUM CHLORIDE.
