Polymerization of propylene with a chromium oxide catalyst activated with a trihydrocarbon aluminum modified with water |
| abstract |
PROPYLENE IS POLYMERIZED TO ISOTACTIC POLYPROPYLENE IN HIGH YIELDS AND AT A HIGH RATE USING AS THE CATALYST A CHROMIUM OXIDE EXTENDED ON A SILICA AND ACTIVATED WITH A TRIHYDROCARBON ALUMINUM THAT HAS BEEN REACTED WITH 0.05 TO 1.5 MOLES OF WATER AND OPTIONALLY ALSO WITH 0.05 TO 1.5 MOLES OF AN ALCOHOL OR A PHENOL, THE TOTAL AMOUNT OF WATER AND ALCOHOL OR PHENOL BEING SUCH THAT SOME ALUMINUM-TO-CARBON BONDS REMAIN. PREFERABLY, THE CHROMIUM OXIDE-ON-SILICA CATALYST IS CHROMIC OXIDE THAT HAS BEEN PARTIALLY REDUCED TO FORM ABOUT 55% TO ABOUT 90%. |
