Beschreibung
Zusammenfassung:	The present invention relates to a method for producing cycloalkenamer-containing compositions. The polymerisation of cycloalkenamer is stopped by adding alkyl vinyl ethers. A membrane filtration is subsequently carried out. This type of production produces polyalkenamers which are temperature-stable at 180 DEG C. 本发明涉及一种用于制备含环烯烃的组合物的方法。通过添加烷基乙烯基醚来终止环烯烃的聚合反应。之后，进行膜过滤。这类生产提供了在180℃下热稳定的开环聚环辛烯。
