Anionic Polymerization of epsilon-Caprolactam in the Presence of Aromatic Poly(imides) As Macromolecular Activators

摘要

It was shown that,in principle,aromatic poly(imides) soluble in a molten [epsilon]-caprolactam can be used as macromolecular activators of anionic polymerization due to involvement of five-membered imide cycles of these polyheteroarylenes in the process.As a result,partially crosslinked graft polymers arise which exhibit improved,compared to unmodified poly (caproamide),thermal and tribological characteristics and water resistance.
