Summary


The effect of temperature in the range from -10 to +80°C on the course of ethylene polymerization in the pre­sence of a catalytic system composed of n-butyllithium and tetramethylethylenediamine has been investigated. An in­crease of the initial rate of polymerization and a reduction of the period of catalyst activity with an increase of temperature has been observed. The optimum temperature range, in which the polymer yield reaches maximum, was 50 - 60 °C. Polyethylene waxes with molecular masses up to Mn 2500 have been obtained.
