PROCESS AND PLANT FOR MANUFACTURING POLYETHYLENE-DIENE-COPOLYMERS

摘要

The present invention provides a process for manufacturing polyethylene-diene-copolymer conducted in a plant comprising at least one compressor unit (10), at least one preheater unit (20) being downstream of the compressor unit (10) and at least one reactor (30), in particular a reactor, being downstream of the compressor unit (10) and the preheater unit (20) a) Feeding a first feed stream (1) comprising ethylene into the at least one compressor unit (10) and subsequently into the at least one preheater unit (20), b1) Feeding a second feed stream (2) comprising at least one diene comonomer to the first feed stream (1) leaving the at least preheater unit (20), and feeding the combined feed streams (4) comprising ethylene and the at least one diene comonomer to the at least one reactor (30), and/or b2) Feeding a second feed stream (2) comprising at least one diene comonomer to the at least one reactor (30) at at least one location along the reactor (30).
