Verfahren zur modifizierung von polymeren

In diesem Verfahren werden Polymere, die Carboxyl-, Amino- und/oder phenolische Hydroxylgruppen aufweisen, mit Delta-2-Oxazolinen umgesetzt, die in 2-Stellung durch den Phenylrest oder einen langkettigen Alkyl- oder Alkenylrest mit 7 bis 23 C-Atomen substituiert sind. Die Reaktion verläuft schnell und führt im Ergebnis zu einer Verbesserung der Hydrolysestabilität von Polyestern und Polyamiden. Bei Verwendung von entsprechenden Bisoxazolinen wird zusätzlich eine Erhöhung des Molekulargewichts erreicht.

Process for modifying polymers

A process for modifying polymers containing carboxyl, hydroxyl and/or phenolic hydroxyl groups. In the process, the polymers are reacted with a delta 2 mono- or bis-oxazoline, each substituted in the 2-position by an optionally substituted alkyl or alkenyl group containing from 7 to 23 carbon atoms. The modified polymers show reduced melt viscosities, lower adhesion and better slip characteristics than unmodified polymers.
