COPOLY(ESTER-AMIDES) AND COPOLY(ESTER-URETHANES)

摘要

The invention provides biodegradable copolymers of the copoly(esteramide) or copoly(esterurethane) type, which copolymers consist of building blocks with the general structure (I): -[-CB-VB-]- wherein CB and VB of different building blocks may be the same or different, and CB represents a block with a constant length and VB represents a block with a variable length.
