Abstract:
Oligo-E-caprolactones(e-CL) have been utilized as principle secondary
components Within poly(lactic acid)[PLA]-based blends as well as additives within larger-
sized PCLPLA blends m an effort to fully complement the mechanical attributes of the
respective polyesters. Dynamic mechanical thermal analysis(DMTA) shows that the
presence of e-CL plasticizes the PLA non-crystalline phase with a more pronounced effect
seen as the size of 0-CL is reduced. Moreover, it appears that the size of 0-CL could also
affect the static mechanical properties of the ternary systems as material mess and
strength reside between those properties measured for high molecular weight PCLPLA
bmary blends and the PLA homopolyester. Future work will examine the ability of these
blends to sustain these properties during hydrolytic exposure.
