The number and weight average molecular weights as well as a comparison of the GPC chromatograms after 35 min of both measurement series are shown in Figure and Figure . A high PDI in the range from 4 to 7 can be observed over the entire observation period, due to the weight average molecular weight, which is significantly higher than the number average molecular weight. This results from a broad molecular weight distribution. Since the yield of oligomers with the highest mass fraction is crucial, the weight average molecular weight is considered in the following discussion.
