Abstract: A polymer composition may include an elastomeric ethylene-vinyl acetate, in which at least a portion of ethylene from the elastomeric ethylene-vinyl acetate is obtained from a renewable source of carbon. A curable polymer composition, an expandable polymer composition, articles, cured articles, and expanded articles may include or be formed from such polymer composition. A process for producing a polymer composition may include polymerizing ethylene at least partially obtained from a renewable source of carbon with vinyl acetate to produce an ethylene vinyl acetate copolymer; and mixing the ethylene-vinyl acetate copolymer with an elastomeric polyolefin to produce an elastomeric ethylene-vinyl acetate.

Abstract: A copolymer may include ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. Embodiments may also be directed to curable polymer compositions, expandable polymer compositions, articles, cured articles, and expanded articles formed from or including such copolymers of ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. A process for producing an ethylene vinyl acetate copolymer may include fermenting a renewable source of carbon to produce ethanol; dehydrating the ethanol, wherein the ethanol is dehydrated to produce ethylene; and polymerizing ethylene and vinyl acetate to produce the ethylene vinyl acetate copolymer.

Abstract: A method of obtaining ketones from a fermentation process may include collecting an off-gas and a fermented broth from a fermenter, transferring the off-gas from the fermenter to a ketone recuperation module and the fermented broth to a fluid separating module, and isolating the ketones from both the off-gas and the fermented broth. The off-gas and the fermented broth may both comprise a ketone.

Abstract: Methods may include obtaining ketones and glycols from a fermentation process, the method including: collecting an off-gas and/or a fermented broth from the fermenter, wherein the off-gas comprises a ketone, and wherein the fermented broth comprises one or more of glycol or ketone; and performing at least one of: transferring the off-gas from the fermenter to a ketone recuperation module; or transferring the fermented broth to a fluid separating module; and isolating one or more of: the ketone from the off-gas; and the glycol from the fermented broth.
