Abstract
A composition may contain a first polymer, a second polymer, and a block copolymer. The first polymer may be polylactic acid, starch, polybutylene succinate, poly(butylene adipate-co-terephthalate), or a mixture thereof. The second polymer may be polybutadiene, high impact polystyrene, or a mixture thereof. The block copolymer may be a block copolymer of polylactic acid and polybutadiene. The composition may be prepared by a process that includes contacting the first polymer with the second polymer and the block copolymer. Articles may be prepared from the composition.
