      摘要:Microwave irradiation is used in the polymerization as a novel and effective way of heating. Microwave irradiation, which is compared with the traditional heating method, has the advantages of short time, low energy consumptions and high product yield. In recent years, applications of microwave irradiation in many chemical fields have been reported. This paper reviews that microwave irradiation has been applied in polymerization including emulsion polymerization, solution polymerization and bulk polymerization. The differences between the microwave irradiation polymerization and the normal heated polymerization have been discussed.

      摘要:There exist unavoidable drawbacks in the common methods to explore the phase behavior of multi-component polymer systems. Instead, the dynamic rheology research in this field has unique advantages over those methods. This methodology is theoretically based on the fact that, for the multi-component polymer systems exhibiting critical phase behavior (LCST, UCST) or micro-phase separation, their dynamic rheological response under the small strain confition is very sensitive to the formation and evolution of the morphology and structure during the phase separation process, and the presence of the heterogeneous structure leads to the different viscoelastic relaxation behavior from the corresponding homogeneous counterparts in the long time relaxation region. That is, it deviates from the classical linear viscoelastic theoretical models by the enhanced elasticity, much longer relaxation time and breakdown of time-temperature superposition principle (TTS) . The advances in studies on the phase behavior of multi-component polymer systems by such dynamic rheology methods as Hah plot, Cole-Cole plot, breakdown of TTS and G′~ Tplot were reviewed in this paper.

      摘要:A research on developments of the synthesis, liquid crystalline (LC) behavior and potential applications of several types of metallomesogenic polymers is provided based on the latest literatures. It is pointed out that four techniques such as direct coordination, monomer coordination, cross-linking coordination and polymer reaction are served for the synthesis of the metallomesogenic polymers. Metallomesongenic polymers are usually thermotropic and exhibit stable nematic or smectic LC phase. Some metallomesogenic polymers show enantiotropic smectic C and smectic A phases, and some are monotropic. Metallomesogenic polymers have special properties like metals. They are magnetically, electronically, optically conducting materials with high performance. These polymers could be potentially served as LC display materials, magnetic data-storage film materials, lubricant as well as anisotropic catalyst.
