Abstract
Embodiments of poly-lactide compositions are disclosed herein. The compositions may comprise at least one first polymer selected from polylactide-polybutadiene (PLA-PB) block copolymer, polylactide-urethane-polybutadiene block copolymer, or a mixture thereof; and at least one second polymer selected from polylactide, polylactide-urethane, or a mixture thereof. The composition may also comprise from 20% to 50% by weight of said first polymer based on the total weight of the composition and from 50% to 80% by weight of said second polymer based on the total weight of the composition. Embodiments of the present invention also relate to a process for preparing the poly-lactide compositions and articles comprising the poly-lactide compositions.
