Polymerization of olefins in the presence of polymer supported Ziegler-Natta catalysts

摘要

alpha -Olefins are polymerized in the presence of Ziegler-Natta catalysts which are polymer supported compounds or complexes of elements of the d-block transition metals, lanthanide or actinide series. An example of the polymer support is chloromethylated polystyrene-divinyl benzene copolymer covalently bonded to catechol. An example of the compound or complex of an element of the transition metal, lanthanide or actinide series is that which results when catechol which is covalently bonded to the polymer is contacted with titanium tetraisopropoxide.
