THE ROLE OF LOW MOLECULAR WEIGHT ALIPHATIC AMIDE ON THE CRYSTALLIZATION BEHAVIOR OF POLY (L-LACTIC ACID)
As one of biodegradable polymers, poly (L-lactic acid) (PLLA) can be synthesized from renewable resources, and decompose into nontoxic products like CO_2 and H_2O. Due to its environmental friendliness, PLLA has attracted much attention. It has been used for medical devices such as controlled drug release matrixes. Besides, it has good mechanical properties, making it a promising material for many disposable products in substitute of petroleum-based polymers. However, the crystallization rate is rather slow which affects the processability of PLLA. In general, the crystallization rate can be improved through the addition of inorganic particles1-3, blending with other polymers4-6 and so on. The crystallization behavior of PLLA in the presence of low molecular organic additives has been seldom studied.
