Abstract

The present invention relates to a process for manufacturing polyethylene-silane-copolymer conducted in a plant including at least one compressor unit and at least one reactor downstream of the compressor unit. The process includes the steps of (a) feeding a first feed stream including ethylene into the at least one compressor unit and subsequently to the at least one reactor, and (b1) feeding a second feed stream including at least one silane comonomer to the at least one reactor as front feed and/or (b2) feeding a second feed stream including at least one silane comonomer to the at least one reactor at at least one location along the reactor.
