摘要：

The morphologies of three low-molecular-weight poly(styrene-b-isoprene) diblock copolymers and their blends with homopolystyrene (hPS) at 66 vol% styrene have been investigated. Addition of hPS to one copolymer produces lamellar-catenoid or double-diamond morphologies, depending on hPS chain length. In another blend, microstructural disorder arises.
