A METHOD FOR PRODUCING SUPPORTED CATALYST FOR ETHYLENE POLYMERIZATION AND ETHYLENE/ALPHA-OLEFIN COPOLYMERIZATION

摘要

AN METHOD FOR PRODUCING A SUPPORTED CATALYST SUITABLE FOR ETHYLENE POLYMERIZATION AND FOR ETHYLENE / ALPHA-OLEFIN COPOLYMERIZATION IS OFFERED, WHICH COMPRISES THE REACTION OF AN ORGANOMAGNESIUM COMPOUND WITH THE COMPOSITION OF MGPH2 NMGCI2 MR2O (WHERE N=0.37~0.7; M >0.5;R2O IS ETHER; PH IS C6H5) WITH CARBON TETRACHLORIDE IN THE MOLAR RATIO OF CCI4/MG<0.5 AT A TEMPERATURE OF -20° TO +60°C.
