Beschreibung
Zusammenfassung:	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.
