Characterization of cyclic arylene ether oligomers by MALDI-TOF mass spectrometry

摘要

The in situ transformation of macrocyclic oligomers such as aryl thers~([1-2]) via an anionic ring-opening polymerization route to high molecular weight linear polymers opens up the possibility of metl processing of aromatic thermoplastics in applications such as the fabrication of long or continuos fiber-reinforced thermoplastics composites which are currently not accessible to the ocrresponding high molecular weight polymers due to their inherent high metl visosities.
