Tailoring toughness of fully biobased poly(lactic acid)/natural rubber blends through dynamic vulcanization

Direct blending of poly(lactic acid) (PLA) with elastic natural rubber (NR) could not generate highly toughened blend, due to immiscibility between PLA and NR. In this study, we improved the compatibility of PLA/NR blend by dicumyl peroxide (DCP) initiated dynamic vulcanization and systemically investigated the effect DCP content on the morphology and mechanical properties of the resulting fully biobased PLA/NR blends. Both the pristine PLA/NR...
