    Abstract

    Polypropylene is one of the most widely used polymers in our daily lives. The catalyst that used in the polymerization is the kind of coordination complexes catalyst; the name is Ziegler-Natta catalyst. The function of this catalyst is produce high stereoregularity polypropylene is isotactic polypropylene. This catalyst is very expensive; therefore, it is nececarry to determine the optimum mileage (g propylene per mg catalyst). In this research was determined mileage in polymerization of propylene used catalyst TiCl4 and co-catalyst triethyl aluminium (TEAL). Polymerization reaction conducted in the autoclave reactor at 34 bar, the reactor was equiped with temperature and pressure control. Three tousands ml propylene (5 bar) was introduced to the reactor, was followed by the catalyst TiCl4, co-catalyst TEAL, donor CHMMS (cyclo hexyl methyl methoxy sylane) and hydrogen. Reaction was done at certain temperature and time. At reaction finished propylene was weighed, isotactic polypropylene and molecular weight was analyzed. At the optimum condition: 75oC, 2 hours reaction time, catalyst 20,55 mg and hydrogen 6,8 bar (in the 250 ml tube); the result is mileage 72,476 g propylene/mg catalyst. In addition, at temperature range 60- 80oC, the molecular weight polypropylene was 170.476 – 357.189 and isotactic polypropypene was 96- 99%. keyword: polypropylene, mileage, isotactic
