Toughening of poly(lactic acid) by ethylene-co-vinyl acetate copolymer with different vinyl acetate contents

Influence of compatibilizer on the structure properties of polylactic acid/natural rubber blends

“…This result can be attributed to improve dispersion of materials and higher energy absorbance through debonding and also lower occurrence of flaws introduced by blends agglomerations indirectly leading to better toughness of PLA/NR blends. In addition, the success of rubber toughening can be achieved by controlling the extent of phase separation, the interfacial adhesion, the particle size and the rubber content [21].…”

Cardanol derivatives as innovative bio-plasticizers for poly-(lactic acid)

“…The most widespread used approach in order to improve polymer ductility, is the use of plasticizers [8,9], potentially able to reduce the glass transition temperature of the polymer. Compared to other approaches, as reactive extrusion, involving for example polymer grafting [10,11], blending with plasticizer represents an easier and faster way to improve PLA mechanical properties.…”

Free radical competitions in polylactide/bio-based thermoplastic polyurethane/ free radical initiator ternary blends and their final properties

“…Polylactide (PLLA), one of the most prominent and readily available bio-based and biodegradable polymers, exhibits outstanding physical and mechanical properties, and some other attractive merits [4e7]. However, the brittle nature of PLLA homopolymer, poor ductility and impact toughness, limits its use in applications where mechanical toughness is required [8]. Extensive strategies have been developed to improve its ductility and toughness such as plasticizing, copolymerizing lactide with other monomers, preparing nanocomposites and melt blending with elastomeric polymers [6,7,9e16].…”
