Biodegradable, amorphous copolyester-urethane networks having shape-memory properties

Abstract

In great shape: Star-shaped telechelic oligomers can be coupled with a junction unit to yield amorphous copolyester-urethane networks, which are not only biodegradable but can also be fixed in a new, temporary shape after they have been processed into a permanent shape. The permanent shape can be recovered by heating (see picture). Such polymer networks may find application in ophthalmology. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
