Spletδ1 −δ2 < 0.5 (solubility) • Measuring the solubility parameter of a low-molecular-weight solvent is no problem. • Polymers degrade long before reaching their vaporization temp, making it impossible to evaluate ΔEν directly. • The greatest tendancy of a polymer to dissolve occurs when its solubility parameter matches that of the solvent. SpletHildebrand SP of PBAT is 21.9 and the one of PLA is 20.7 or 19.9 [MPa 1/2 ] respectively (Table 3). Due to the small difference of the solubility parameters, the PBAT/PLA blends need be... dow level on november 30 2020
Hildebrand solubility parameters of PBAT and PLA
SpletBlending PLA with PBAT (Poly(butylene adipate-co-terephthalate)), an aliphatic-aromatic copolyester, was the solution found due to its high toughness and biodegradability. Differences between PLA and PBAT solubility parameter values lead to the formation of immiscible blends as well as reduction in their mechanical performance besides a poor ...
