Slurry Polymerization of Ethylene in the Presence of Fatty Amine Anti-fouling by Ziegler-Natta Catalyst through a 23 Full Factorial Experimental Design

A full factorial experimental design for the evaluation of slurry polymerization of ethylene in the presence of fatty amine anti-fouling, Armostat 300, is employed. The parameters studied as independent variables are: AI/Ti molar ratio, temperature and anti-fouling concentration (g/mmol Ti). The catalyst activity, MFI, Tm and X^% of polymer were measured and statistically analyzed through surface response method. It was found that anti-fouling concentration has a significant effect on the catalyst activity (kg PE/g Ti.h) and it does not, however, affect the polymer properties. Temperature has a significant effect on MFI and Tm. It is found that independent variables have no effect on the crystallinity of polymer.
