Abstract

POSTUPAK ZA POLIMERIZACIJU ETILENA, naznačen time, što obuhvata: kontaktiranje etilena na temperaturi od -18 C do 233 C (0-450 F) i pritisku, najpoželjnije u opsegu od 0.6 do 4.8 MPa (100-700 psia) sa katalizatorom koji obuhvata čvrstu neorganski oksidni nosač i jedinjenje hroma koje ima formulu: Crn (R) 2n u kojoj je: n ceo broj 3 ili više, R je ligand koji ima formulu: -CH2-MR1R2R3 u kojoj je M C, Si, Ge, Sn ili Pb, poželjno Si, R1, R2, R3, koji mogu biti isti ili različiti, su hidrokarbil supstituenti koji sadrže ugljenikove i vodonikove atome, da bi se dobila reakciona smeša koja sadrži polimer etilena, i što se vrši regenerisanje pomenutog etilenskog polimera iz reakcione smeše. Prijava sadrži još 8 patentnih zahteva.
