Abstract

image

A special external component (triphenyl phosphate), which was introduced into the iron(III) complexes system was studied. Some of the greatly affected parameters include the catalytic activity, stereospecificity (obvious increases of 3,4 content), polymer molecular weight, and molecular weight distribution.
