Abstract
1410106 Ziegler-Natter polymerization catalysts ETHYLENE PLASTIQUE 11 Sept 1973 [14 Sept 1972] 42722/73 Heading C3P Polymers of alpha-olefins are prepared by polymerizing the olefin in the presence of a stereo specific Ziegler-Natter catalyst, and also 0.01 to 10 millimoles of an additive selected from furfuraldehyde, pyrrole-2-aldehyde, and methyl pyrrole-2-aldehyde, per litre of reaction mixture, said additive increasing the stereo specificity of the catalyst. Examples of olefins which may be polymerized are propylene, but-1- ene, pent-1-ene, 3-methyl-but-1-ene, 4-methylpent-1-ene, and hex-1-ene. In the examples a mixture of diethyl aluminium chloride and TiCl 3 .<SP>1</SP>/ 3 AlCl 3 is used as the Ziegler-Natter catalyst. Isotactic polymers are produced.
