| Abstract: | Based on the TEM observations of the morphologies of the blends under small stretching process, this communication reports the results for the toughness and deformation mechanisms of two typical blends in which the tough component LDPE is minor(LDPE/PS=20/80) and major(LDPE/PS=80/20) constituents respectively. It is found that multi-craze is the main toughness and deformation mechanism when LDPE is the dispersed phase, while microbands caused by shear-yielding becomes major one while LDPE is continuous phase. |
