Abstract

Opisan je postupak za proizvodnju etilen-buten-1 kopolimera koji imaju vrednosti gustine od oko 0,880 do oko 0.914 g/ml, za kopolimerisanje etilena i butena-1, na visokoj temperaturi i visokom pritisku, u reakcionom sudu ili cevnom reaktoru, u prisustvu katalizatora koji se sastoji od aluminijum trialkila i čvrste komponente katalizatora koja sadrži 0.4 do 4 mas.-% titana na mikrosferoidnom magnezijum hloridnom nosaču, u kome je titan prisutan delimično u trovalentnom i delimično u tetravalentnom obliku.
