Preparation of propylene copolymer with dynamically operated reactor
摘要:
The present invention relates to a process for the preparation of a propylene copolymer P1 having ethylene-derived comonomer units, which comprises the following steps: (i) introducing propylene, ethylene, and hydrogen into a polymerisation reactor R1, wherein the ethylene is fed to the polymerisation reactor R1 in a periodically varying amount, (ii) preparing the propylene copolymer in the polymerisation reactor R1 in the presence of a catalyst.
