  • BIODEGRADABLE BLOCK COPOLYMERS WITH MODIFIABLE SURFACE
    Publication number: 20090291106
    Abstract: A block copolymer containing a) a hydrophobic biodegradable polymer, b) a hydrophilic polymer and c) at least one reactive group for covalent binding of a surface-modifying substance d) to the hydrophilic polymer b) is disclosed. Shaped bodies are formed to consist of the block copolymer and are utilized as carriers for tissue culture and active substances and for controlled release and targeted administration of active substances.
