Procedure

To a scintillation vial was added 267 mg of the poly(α-methylene-γ-butyrolactone-acrylic acid) prepared in Example 14 and 5.14 mL DMSO on a platform shaker. Once dissolved, the solution was pipetted onto a foil-lined steel panel and placed in a 100° C. oven. Vacuum was applied to remove the solvent over approximately 60 minutes. The result was a 2 cm×2 cm transparent poly(α-methylene-γ-valerolactone-acrylic acid) film.
