Abstract
Polyester resins (C) of the invention have a practically sufficient high molecular weight and a high crystallinity and have an amide group in the molecular chain. Processes for producing the polyester resins are also disclosed. In detail, the polyester resins (C) have a practically sufficient high molecular weight and a high crystallinity and have a biodegradable amide group in the molecular chain. Processes for producing the polyester resins are also disclosed. The polyester resins (C) are obtained by reacting an aliphatic polyester resin (A) and a polyisocyanate compound (B) in the presence of an amidation catalyst and contain a specific structural unit.
