Abstract

Ethylene and/or propylene are polymerized in an organic medium and with a Ziegler type catalyst, characterized in that the reaction medium is continuously circulated in a closed cyclic unidirectional tubular system at a temperature between 20 and 100 DEG C. and with polymer suspension being continuously withdrawn. A suitable apparatus is described with reference being made to circulation speeds, reactor dimensions and polymerization conditions. In an example ethylene is polymerized in a petroleum fraction using TiCl4 + AlEt3. The polymer obtained is washed with acid and alkali.
