In the system investigated, different morphologies
were observed, depending on the hPS molecular
weight, blend composition and processing method,e.g. see Figs. 14 and 15; details in Refs. [68,95–97].
Consequently, a wide range of mechanical and
micromechanical properties were observed. In this
section, we confine the discussion to the strain
induced structural changes in two different types of
blends: macrophase-separated blend containing hPS
particles [94] (solution cast), and blends with layered
structures (injection mold) [68].
