Halogen-free soluble Ziegler catalysts with methylalumoxan as catalyst

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

A soluble, halogen-free Ziegler-catalyst can be obtained when using bis(cyclopentadienyl)dimethyltitanium together with methylalumoxane. It is possible to polymerize both ethylene as well as propene with high activities. The so formed polypropylene is 100 % atactic. Polymerization activities in dependence upon Al- and Ti-concentrations and polymerization rates of ethylene and propylene are shown.
