Abstract

A process for polymerizing .alpha.-olefins in a solvent under conditions such that the polymer formed grows as particles, in which the process comprises reusing a greater part of the solvent used for the polymerization by recycling the solvent to the polymerization zone without carrying out any purification treatment.
