摘要：

The useful lifespans of a poly(lactic acid)/poly(methyl methacrylate) (PLA/PMMA) 80/20 (wt%) blend and a poly(lactic acid)/dioctyl adipate/talc (PLA/DOA/talc) compound have been estimated by applying an Arrhenius relationship to the evolution of the mechanical properties whilst ageing. The studied PLA based systems showed lower activation energies (ca 8 - 20 Id mol(-1)) than those reported in the literature for other synthetic thermoplastics, indicating lower thermo-oxidative stability. However, both systems were interesting choices for semi-durable applications in terms of useful lifespan estimations. The PLA/PMMA blend showed a drastic loss in stiffness at T-g due to its almost amorphous structure whereas, in contrast, PLA/DOA/talc showed acceptable mechanical properties above its glass transition temperature due to its semicrystalline structure.
