摘要：
The invention is directed to an improved system for controlled release of biologically active materials and to a liquid composition for its formation. The liquid composition is composed of a thermoplastic polymer, rate modifying agent, bioactive material and organic solvent. The liquid composition is capable of forming a biodegradable and/or bioerodible microporous, solid polymer matrix. The matrix is useful as an implant in patients (humans and animals) for delivery of biologically active substances to tissues or organs.
