Summary

The copolymerization of propylene with small amount of ethylene using MgCl2-supported stereospecific catalysts in combination with different Al-alkyls was performed. At least for the particular catalyst used, it resulted that TEA and TIBA are the preferred Al-alkyls; whereas, the mixture TEA/DEAC provides copolymers with a high amount of xylene solubles. Finally, the mixture TEA/DEAI largely decreases catalyst activity, but it provides a copolymer with broad MMD.
