Fund Project: This project was financially supported by National High Technology and Development Program of China (863 Program No. 2003AA33G030).

Block copolymers with different backbone compositions have been prepared by the condensation of dimethylamino terminated poly (dimethylsiloxane)(PDMS) and hydroquinone terminated poly (phthalazinone ether nitrile)(PPEN) in the presence of chlorobenzene/N-methyl pyrrolidone (NMP) as solvents.The products were characterized by FTIR, ¹H NMR and gel permeation chromatography.Differential scanning calorimetry analysis indicated that the block copolymers showed separated microphase.
