In order to investigate the effects of an external electron donor on catalyst active sites in propylene polymerization, physical properties of the produced polymers are measured with various techniques. From the thermal analysis and gel permeation chromatography (GPC) measurement, it is found that a

Al~tract--The rate of anionic polymerization of bulk propylene oxide catalysed by potassium alkoxide in the presence of 18-crown-6 ether was followed dilatometrically. Rate constants were obtained at 40, 50 and 60 Β° over a range of crown ether concentrations, so allowing calculation of activation en
