X. Liu et al., THERMAL AND MECHANICAL-PROPERTIES OF POLY(LACTIC ACID) AND POLY(ETHYLENE BUTYLENE SUCCINATE) BLENDS/, Journal of environmental polymer degradation, 5(4), 1997, pp. 225-235
In this study, blends of poly(lactic acid) (PLA) with poly(ethylene/bu
tylene succinate) (Bionolle) have been investigated for their thermal
and mechanical properties as a function of the concentration of Bionol
le. Differential scanning calorimetry (DSC), dynamic mechanical analys
is (DMA), and tensile tests were used to characterize the blends. From
the results of the DMA and DSC, it was found that this blend system w
as not miscible within the compositions studied. DSC results showed th
at adding Bionolle aids in crystallization of PLA. It was observed tha
t increasing the Bionolle concentration led to a slight increase in th
e strain-at-break of the blends but a decrease in the Young's modulus
and ultimate tensile strength. Biaxially oriented films showed an incr
ease in tensile strength, modulus, and strain-at-break.
