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.

Claim (Index 8):
A thermoplastic compound, comprising the copolymer of  claim 1 , wherein the copolymer is an in-situ reaction product of polyvinyl butyral and lactide monomer polymerized on a backbone of the polyvinyl butyral to form grafts of polylactic acid in presence of a catalyst, optionally plasticizer, and optionally chain extender.
