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 target controlled stimuli-sensitive drug release, as ligament augmentation and as replacement material for inter-vertebrae disks.
Claims12
An interpenetrating network comprising a polymer component that is covalently crosslinked, obtainable by crosslinking the polymer component in the presence of a polyester urethane, wherein the polyester urethane comprises at least segments derived from pentadecalactone and segments derived from partially crystalline segments that comprise polyester segments, polyether ester segments, or polyether segments, or glassy segments that comprise polyester or copolyester, and wherein the polyester urethane is not crosslinked and not covalently bonded to the polymer component.
