ETHYLENE POLYMERIZATION IN A HIGH PRESSURE REACTOR WITH IMPROVED INITIATOR FEEDING

摘要

Pressure reactor having at least two spatially separated initiator injection points by polymerizing ethylene and optionally further monomers under a pressure of from 100 to 350 DEG C and from 160 to 350 MPa in the presence of at least two different mixtures of free radical polymerization initiators, A method for producing an ethylene homopolymer or copolymer, a) providing at least two different initiators as a suitable solvent or liquid solution, b) mixing the initiator and optionally further solvent in at least two static mixers, and c) feeding each of said mixtures to different initiator injection points in a high pressure reactor, An apparatus for supplying an initiator mixture to a high pressure reactor having at least two spatially separated initiator injection points.
