Characterization of Poiy (diethylene glycol adipate -co- neopentylglycol adipate) as a New Plasticizer for Poiy (lactic acid)

摘要

A new poly (diethylene glycol adipate -co- neopentylglycol adipate) (PDNA) was synthesized from diethylene glycol adipate (DEAP) with neopentylglycol adipate (NPAP). The chemical structure of PDNA was characterized by 'H-NMR. PLA was plasticizcd by various amount of PDNA to obtain biodegradable blends. The effects of both temperature and shear rate on the rheologies of PLA/PDNA blends were evaluated by a parallel plate rheometer.
