Abstract

The present invention relates to the penetrating networks comprising a covalently crosslinked polymer component and a polyester urethane component. The materials in accordance with the present invention are suitable in particular as materials for medicinal purposes, as implants, for the target controlled stimuli-sensitive drug release, as ligament augmentation and as replacement material for inter- vertebrae disks.
