Supertough poly(lactic acid)/bio-polyurethane blends fabricated by dynamic self-vulcanization of dual difunctional monomers

Toughening polylactide with nonlinear, degradable analogues of PEG and its copolymers

“…13 Various additives, e.g. poly(ethylene glycols), 14 poly(ethylene oxide), 15 low-density polyethylene, 16 poly(ε-caprolactone), 17 natural rubber (NR), 18 epoxidized natural rubber (ENR) 19 and crosslinked polyurethane (CPU), 20 have been investigated in this regard. In 1999, Jacobsen and Fritz 14,16 investigated PEG as a partially miscible (depending on molecular weight and blending ratio) plasticizer for PLA toughness enhancement by melt blending.…”

On the Production of Poly(Lactic Acid) (PLA) Compounds with Metallic Stearates Based on Zinc, Magnesium and Cobalt. Investigation of Torque Rheometry and Thermal Properties

“…In addition, the growing importance of sustainable industry has increased the need to improve PLA performance, aiming to replace commodity polymers for practical applications. There are several current reports on alternatives to address PLA deficiencies, such as heat treatments [32][33][34] to increase its thermomechanical stability, production of blends [35][36][37] to improve impact strength, ductility, and thermal stability, as well as in the development of eco-composites. 38,39 Although PLA costs more than commodity polymers, consumption is increasing rapidly.…”
