Experimental Investigation of Z-N Catalyst Pre-contacting on Polymerization

Description

Polyolefines account for about one third of the plastics production, with heterogeneous Ziegler-Natta (Z-N) based catalysts dominating the polyolefin production. Since the first Z-N polymerization in 1953 by Karl Ziegler and his research team, there is a constant progress in catalyst design to increase the catalyst activity and powder morphology [1]. Beside the catalyst design there are further possibilities to enhance a catalyst system. It is described that pre-treatment of the catalyst can influence the activity of the catalyst system and particle morphology [2]. Especially co-catalyst (aluminium alkyl) diffusion into the catalyst particle is very important for the catalyst activation, like described in Figure 1 [3].
