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 apolymer 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. 聚合物组合物可以包含弹性体乙烯-乙酸乙烯酯，其中弹性体乙烯-乙酸乙烯酯中的至少一部分乙烯从可再生碳源获得。可固化聚合物组合物、可发性聚合物组合物、制品、固化制品和发泡制品可以包含这样的聚合物组合物或者由这样的聚合物组合物形成。用于制备聚合物组合物的方法可以包括使至少部分地从可再生碳源获得的乙烯与乙酸乙烯酯聚合以制备乙烯-乙酸乙烯酯共聚物；并且将乙烯-乙酸乙烯酯共聚物与弹性体聚烯烃混合以制备弹性体乙烯-乙酸乙烯酯。
