Phosphonium ionic liquids as new compatibilizing agents of biopolymer blends composed of poly(butylene-adipate-co-terephtalate)/poly(lactic acid) (PBAT/PLA)

AbstractSolvent properties of ionic liquids with trihexyltetradecylphosphonium cation and bis(2,4,4-trimethylpentyl)phosphinate anion (Cyphos IL-104) or chloride anion (Cyphos IL-101) were studied. IL-104 effectively extracted lactic acid (LA) with distribution coefficients above 40 at low acid concentrations. IL-104 extracted only undissociated acid (LAH) what supported the coordination mechanism of lactic acid extraction via H-bonding. In the extraction of lactic acid by phosphonium chloride (IL-101) an ion-exchange mechanism contributed remarkably to the extraction especially at basic pH where anionic form of this acid predominated. A high solubility of water in hydrophobic IL-104 up to 14.4 mass % was connected with the formation of reverse micelles. A dual mechanism of water extraction to phosphonium ionic liquids was identified, which consisted of water incorporation into reverse micelles and the inclusion of water into the hydrated complex of lactic acid with ionic liquid (IL). The extraction of lactic acid caused splitting of reverse micelles with liberation of water from the solvent. In the saturated solvent only hydration water remained in the complex of lactic acid with phosphonium ionic liquid, with the suggested structure (LAH)p(IL)(H2O)2, where the value of p ranged from 1 to 3.

In this paper hexafluorophosphate anionic ionic liquid monomer. Through the ion exchange ([2-(methacryloyloxy) ethy trimethyl ammonium hexafluoro phosphate ionic liquids) ([MATM[PF6]) was prepared. Also through the atom transfer radical polymerization (ATRP), the required poly (ionic liquid) (PIL) was easy to gather and had a very high yield, mixed with polylactic acid in solution and observed on the influence of PLAs crystallinity and compatibility. From differential scanning calorimeter (DSC) analysis results are seen that poly (ionic liquid) concentration in a certain range goes against poly (lactic acid)(PLA) crystallization and reduces the ability of crystallization.
