Abstract The living polymerization of propene was conducted at 0°C using a chelating diamide complex of titanium combined with dried modified methylaluminoxane from which free trialkylaluminium compounds were removed as much as possible before use. The number‐average molecular weight of the statistically atactic poly(propylene) produced increased almost linearly with increasing polymerization time accompanied by a narrowing of the molecular weight distribution from 1.34 to 1.16.
