        摘要：In this review , some recent developments in the field of compatibilization for insitu composites containing liquid crystalline polymers are presented. Four routes for compatibilizing are considered, namely, adding third components, incorporating similar segments in LCP chains, transesterification, and blending with ternary polymers. Finally, the prospect of in-situ composite is also briefly commented.

        摘要：The study of the hexagonal phase of polyethylene was carefully reviewed from aspects of its lattice structure, conformation and thermodynamic features. The reason of Polyethylene to form hexagonal structure is also analyzed. The kinetic role of this metastable intermediate phase in crystallization, especially informing ECC, was thoroughly elaborated.

        摘要：This paper briefly introduces the formation and fluorescence emission of excimer of pyrene chromophore based on its steady-state fluorescent spectra. The method and pattern for chemically labeled pyrene groups onto polymer chains are also illustrated. We discuss the excimer formation of pyrene labeled on water-soluble polymers and review applications of the excimer spectra on studying hydrophobic interaction, electrostatic interaction, hydrogen bonding, complex and so on. This excimer fluorescence of pyrene labels is also used in research of the volume phase transition of polymer gels and the molecular chain dynamics.

        摘要：In this paper, the influence of ionic kind, position and concentration in the polymer chains on liquid crystalline properties was summarized. The kind and position of ions influence liquid crystal range for both main-chain and side-chain liquid crystalline ionomers, but the type of mesogeric phase hardly be changed. The liquid crystalline properties disappear with ionic concentration increase to a value for the different liquid crystalline ionomers.
