TLDR
In this article, the recent progress in PLA toughening using various routes including plasticization, copolymerization, and melt blending with flexible polymers, was reviewed in detail.Abstract:
Renewable poly(lactic acid) (PLA) exhibits high strength and stiffness PLA is fully biodegradable and has received great interest However, the inherent brittleness of PLA largely impedes its wide applications In this article, the recent progress in PLA toughening using various routes including plasticization, copolymerization, and melt blending with flexible polymers, was reviewed in detail PLA toughening, particularly modification of impact toughness through melt blending, was emphasized in this review Reactive blending was shown to be especially effective in achieving high impact strength The relationship between composition, morphology, and mechanical properties were summarized Toughening mechanisms were also discussed © 2011 Wiley Periodicals, Inc J Polym Sci Part B: Polym Phys, 2011read more

Phase structure and adhesion in polymer blends: a criterion for rubber toughening
TL;DR: In this paper, the effects of rubber particle size and rubber-matrix adhesion on notched impact toughness of nylon-rubber blends are analyzed. And the general condition for toughening is that the interparticle distance must be smaller than the critical value.
