Abstract

Sadašnji pronalazak odnosi se na alfa-olefinski prepolimer koji je katalitički aktivan u (ko-) polimerizaciji alfa-olefina i koji obuhvata tranzitni metal, organometalno jedinjenje i antistatičko sredstvo. Prepolimer se može napraviti kontaktiranjem antistatičkog sredstva sa katalizatorom koji obuhvata tranzitni metal i organometalno jedinjenje pre ili za vreme prepolimerizacije alfa-olefina. Takodje se može napraviti kontaktiranjem antistatičkog sredstva sa alfa-olefinskim prepolimerom posle prepolimerizacije. Može se takodje napraviti kombinovanjem dva postupka. Prepolimer se može uvoditi u sredinu za (ko-) polimerizaciju u gasnoj frazi za direktno pravljenje poliolefina u obliku suvog praha, sa smanjenom količinom formiranja poliolefinskih listova i aglomerata.
