Neue Polyester mit Hydroxyl- und Carbonamidgruppen und ein Verfahren zu ihrer Herstellung

Polyesters which contain hydroxyl and carbonamide groups are prepared by copolymerizing a lactone with a lactam in the presence of a low molecular weight initiator which contains at least two active hydrogen atoms at a temperature of from about 50 DEG C. to about 300 DEG C. These polyesters are part...

Beschreibung
Zusammenfassung:	Polyesters which contain hydroxyl and carbonamide groups are prepared by copolymerizing a lactone with a lactam in the presence of a low molecular weight initiator which contains at least two active hydrogen atoms at a temperature of from about 50 DEG C. to about 300 DEG C. These polyesters are particularly useful as plasticizers and stabilizers for polyvinyl chloride.
