  • Biodegradable and hydrodegradable diblock copolymers composed of poly(.beta .
    Patent number: 5439985
    Abstract: A biodegradable and hydrodegradable diblock copolymer includes a naturally-occurring poly(.beta.-alkanoate) component and a chemically synthesized polyester component formed by ring-opening polymerization. A method of forming the biodegradable and hydrodegradable diblock copolymer having a poly(.beta.-hydroxyalkanoate) component and a chemically synthesized polyester component includes exposing a naturally-occurring poly(.beta.-hydroxyalkanoate) to alcoholysis and then to a trialkyl metal to form a dialkyl metal poly(.beta.-hydroxyalkanoate) macroinitiator. The macroinitiator is then reacted with a lactone or lactide reactant to form the biodegradable and hydrodegradable diblock copolymer.
