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%.
