Miscibility and mechanical of poly(lactic acid) and poly(methyl methacrylate) blend

摘要

Poly(lactic acid) (PLA) was melt blend with poly(methyl methacrylate) (PMMA) in various ratios. The miscibility was calculated by Hansen solubility parameters (HSPs), the miscibility was confirmed by DTA because only single T_g was observed at different content, The mechanical property of the composite was studied by tensile test. The morphology of composite was observed by SEM.
