ABSTRACT:
Ziegler-Natta catalysts which are polymer supported compounds or complexes of elements of the d-block transition metals, lanthanide or actinide series are disclosed. 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. These catalysts are useful in preparing polymers with reduced halide content which reduces corrosion in polymer processing equipment.
