USPTO Abstract
The invention is directed to a biodegradable, thermoplastic multiblock copolymer, to a process for preparing a biodegradable, thermoplastic multiblock copolymer, to the use of a biodegradable thermoplastic multiblock copolymer, to a composition for the delivery of at least one biologically active compound to a host, and to a medical device comprising a biodegradable, thermoplastic multiblock copolymer. The biodegradable, thermoplastic multiblock copolymers of the invention comprise at least one prepolymer (A) segment and at least one hydrolysable amorphous prepolymer (B) segment, wherein the segments are linked by a multifunctional chain extender, wherein the prepolymer (A) segment: a) comprises one or more hydrolysable linkages, and/or b) comprises a water soluble polymer; and wherein the hydrolysable amorphous prepolymer (B) segment comprises a specified poly(ortho ester) block.
