摘要： Copolymers of a polyvinyl butyral backbone with polylactic acid grafts and their compounds are disclosed, which can be used to produce clear, flexible and ductile bio-based films. The copolymers are amorphous and have been shown to maintain clarity, flexibility, and ductility after continuous exposure to thermal aging at 80° C. for one week.

摘要： Aliphatic polyimides are synthesized by a 2:1 molar ratio reaction of an unsaturated monoanhydride or an unsaturated diacid with a diamine. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.
