METHOD FOR PRODUCING TEMPERATURE-STABLE POLYALKENYLENES

The present invention relates to a process for producing cycloalkenamer-containing compositions. The polymerization of cycloalkenamer is stopped by addition of alkyl vinyl ethers. This is followed by a membrane filtration. This type of production affords polyalkenamers that are thermally stable at 1...

More Information
Summary:The present invention relates to a process for producing cycloalkenamer-containing compositions. The polymerization of cycloalkenamer is stopped by addition of alkyl vinyl ethers. This is followed by a membrane filtration. This type of production affords polyalkenamers that are thermally stable at 180° C.
