摘要：

The effect of the polyisoprene molecular weight on morphological transition was discussed. Lamellae (L), hexagonally ordered cylinders (HEX) and hexagonally perforated phase (HPL) were also investigated. Results showed that the morphological transition of the blend depend on the molecular weight of the homopolymer.
