Abstract (en)

[origin: WO2005121216A2] The invention relates to a composite system consisting of at least one biodegradable block copolyester urethane, at least one filler consisting of a polysaccharide and/or derivatives thereof in addition to optional additional biocompatible additives. Said composite systems of this type are used for producing moulded bodies, moulded parts or extrudates. The invention also relates to a method for producing a biodegradable block copolyester-urethane by the polyaddition of a polyhydroxyalkanoate diol, a polyester diol of a dicarboxylic acid monoester and a bifunctional isocyanate.
