ABSTRACT:
A process and apparatus for the continuous polymerization of ethene at high pressures and temperatures, in the presence of an initiator. Reaction is carried out in a cylindrical autoclave wherein ethene is fed into the autoclave at a high velocity through nozzles having a restricted opening. The nozzles are fitted and mounted on the autoclave in at least two different places at an angle which is acute to the central axis of the autoclave whereby the direction of flow of the ethene coming from the nozzles is substantially parallel and opposite.
