Title: POLYVINYL BUTYRAL-G-POLYLACTIDE COPOLYMER
Abstract:
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.
