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 20):
A method of making the copolymer of  claim 1 , comprising the step of and situ-polymerization of lactide monomer in presence of a catalyst and vinyl alcohol sites of polyvinyl butyral, wherein the catalyst drives polymerization of the lactide monomer to form polylactide grafts and transesterification between hydroxyl groups on the polyvinyl butyral with ester groups on the lactide monomer.
