Синтез диблочных полиариленфталидов с терфениленовыми и дифениленоксидными фрагментами в основной цепи

The synthesis of diblock copolyarylenephthalides with diphenyloxide and terphenyl fragments in the main chain was carried out by two-phase one-reactor and two-reactor ways. Partition of homopolymers, the initial not reacted polyterphenylenephthalide block and being formed in the process of polydiphenyleneoxidephthalide synthesis, was carried out by methods of extraction and columnar chromatography. Molecular-mass characteristics of produced diblock copolyarylenephthalides were determined by 13С NMR techniques and gel permeation chromatography (GPC). Volt-ampere curves were taken and switching of a thin film of block co-polymer under the influence of the enclosed pressure to conducting state is shown.
