PREPARACIÓN Y CARACTERIZACIÓN FÍSICO-QUÍMICA Y MECÁNICA DE MEZCLAS TERNARIAS DE POLILACTIDA (PLLA), POLICAPROLACTONA (PCL) Y ALMIDÓN TERMOPLÁSTICO (TPS)

摘要: In this work we studied the thermoplastic starch incorporation on physico-chemical, thermal and mechanical properties of ternary blends (TPS), polylactide (PLLA) polycaprolactone (PCL). The TPS worked was obtaining from cassava it plasticized with 30 % (w/w) glycerol using extrusion technology. Five different percentages (10, 20, 30, 40 50 w/w) were varying, maintaining constant relation PLLA/PCL at 70:30. It found that binary blend non-miscible continua phase, strength tensile modulus reduced proportionally to added, also moisture absorption increasing stability in incorporated.
