Abstract: The present invention is directed to compositions comprising polylactone melt, extrudate, and processes for producing a foam. In exemplary embodiments of the present invention, the processes comprise: heating a polylactone composition containing a biobased polylactone in a reaction vessel; and subjecting the polylactone composition to molding to give a foamed structure.

Abstract: The present invention is directed to processes for producing isocyanates and isocyanate derivatives from epoxide and carbon monoxide reagents. In preferred embodiments, the processes include a step for providing carbonylation of an epoxide reagent with a carbon monoxide reagent to produce a beta-lactone intermediate. In certain preferred embodiments, further carbonylation of a beta-lactone intermediate produces a succinic anhydride intermediate. The processes of the present invention include steps for rearranging beta-lactone intermediates and/or succinic anhydride intermediates to produce isocyanate products and/or isocyanate derivatives. In certain preferred embodiments, the isocyanate products may be copolymerized with polyol oligomers to provide polyurethane products.

Abstract: Provided is a method of producing a film by cryogenically grinding polypropiolactone to form a powder, and extruding the powder to form the film. Provided herein are also polypropiolactone films having certain biocontent and compostability, as well as certain mechanical and physical properties. Such films may also be suitable for use as packaging materials.

Abstract: Provided herein are integrated methods and systems for the production of acrylamide and acrylonitrile compounds and other compounds from at least beta-lactones and/or beta-hydroxy amides.
