Structured polymer blends-1

The viscosity ratio and vol. fraction effects in the extruded polystyrene (I)-HDPE blend caused unstable morphol. As a result of gamma ray- or electron beam-induced crosslinking of the dispersed phase (HDPE), the morphol. was preserved to some extent. Due to shielding effects of the I matrix, the crosslinking of HDPE particles was less effective to achieve complete fixation of the morphol. [on SciFinder (R)
