Blending poly(butylene succinate) with poly(lactic acid): ductility and phase inversion effects
journal contribution
posted on 2015-10-14, 13:15 authored by Yixin Deng, Noreen ThomasSynergistic effects of blending two bio-based, bio-degradable polymers, poly(butylene succinate) (PBS) and poly(lactic acid) (PLA) are investigated. A series of melt-blended compounds were prepared at PBS/PLA weight ratios of 0/100, 10/90, 20/80, 40/60, 60/40, 80/20 and 100/0. Thermal properties, crystallinity, melt viscosities, mechanical properties and phase morphology were studied. There was found to be a dramatic improvement in ductility, over 250% elongation-to-break, with as little as 10 wt% of PBS added. This was shown to be due to a co-continuous phase morphology, which was determined by the relative viscosities of the components.
