摘要：

A block copolymer from polystyrene (PS) and poly(diethylsiloxane) (PDES) has been synthesized by sequential anionic polymerization. By DSC, the PDES block was shown to exist in the columnar mesophase at ambient temperatures. By transmission electron microscopy and scanning force microscopy on thin films, the block copolymer was shown to build regular structures, showing a large periodicity, which is unusual for relatively low molecular weight block copolymers and must be ascribed to the fact that the PDES block exists in the mesophase.
