| titleOfInvention | METHOD FOR PREPARING POLYETHENE WITH ULTRA-HIGH MOLECULAR WEIGHT |
| abstract | Polyethylene or ultra high mol. wt. is prepd. by contacting ethylene with a catalyst, contg. (a) a heat-activated organo-phosphoryl-Cr cpd. on (b) Al2O3 with pore vol. 0.3-2.2 (1.2-2)cc/g as carrier. The cpd. (a) is obtd. by reacting CrO3 with (RO)3PO(I) or (RO)2P(OH), (II) where R is (cyclo)alkyl, aralkyl, aryl or H and is not 1 R is nor H. Polyethylene has mol. wt. 1,000,000 to >6,000,000 (is not 2,000,000), and has improved mechanical strength. |
