Abstract
POSTUPAK ZA POLIMERIZACIJU U GASNOJ FAZI, sadašnji pronalazak odnosi se na kontinualan postupak za polimerizaciju alfa-olefina koji ima od 2 do 12 atoma ugljenika, koji se vrši u reaktoru za polimerizaciju u gasnoj fazi dovodjenjem gasne reakcione smeše, koja sadrži alfa-olefin koji treba da se polimerizuje, u kontakt sa katalizatorom na bazi oksida hroma koji je udružen sa granularnim nosačem i aktiviran je toplotnim tretiranjem, u kojem se reaktor za polimerizaciju šaržira sa (a) alfa-olefinom i (b) katalizatorom, i to konstantnim brzinama.
