Propylene Polymerization Performance with Ziegler-Natta Catalysts Combined with U-Donor and T01 Donor as External Donor

In propylene (C3) polymerization with Ziegler-Natta catalyst, not only internal donor but also external is very important to make isotactic polypropylene (PP) higher yield. Most propylene-based polymers have been commercially produced catalysts combined dialkyl-dialkoxy silane compounds (R2Si(OR)2) such as C-donor, P-donor, and D-donor donors. this paper, we will introduce the performance aminosilane compounds, i.e., diethylamino triethoxy (U-donor) bis(ethylamino) di-cyclopentyl (T01 donor), in Ziegler–Natta catalyst. The screening experiments were conducted using some triethoxyalkylsilanes (1–7) performances compared U-donor. results of binary system show improvement stereoregularity. These exhibit high hydrogen response copolymerization ethylene (C2) ICP production compounds. While methanol an additive along electron donor, a serendipitous, activity, block ratio, EPR (ethylene-propylene rubber) content improve significantly for U-donor T01 C-donor.
