Abstract
The effect of the compatibilizers, P(LLA-co-εCL) and P(LLA-b-εCL), on the morphology and hydrolysis of the blend of poly(ε-caprolactone) (PCL) and poly(L-lactide) (PLLA) was investigated. An addition of P(LLA-co-εCL) or P(LLA-b-εCL) into the blend could enhance the compatibility between the dispersed PCL domains and the PLLA matrix. The size of the PCL domains in the PLLA/ PCL (70/30) blend containing P(LLA-co-εCL) reduced more significantly with an increase in the content of the compatibilizer than that in the blend containing P(LLA-b-εCL). The molecular weight of the PLLA/PCL blend films compatibilized with P(LLA-co-εCL) or P(LLA-b-εCL) decreased during the hydrolysis and the decrease of the molecular weight of the blend films compatibilized with P(LLA-co-εCL) was much more significant than that of the blend films compatibilized with P(LLA-b-εCL).
