        摘要：Molecular nanotechnology, based on supramolecular self-assembly, is emerging high technology. The account comprises three parts such as metal vector manipulated self-assembling molecular nanosystems, self-assembling nano-microreactors and supramolecular catalysis, and self-assembly of metallo-supramolecular polymers. The concept of Metal Vector was further interpreted. It is noted that it has been first put forward to establish a tool case for self-assembler for the future development of molecular nanotechnology.

        摘要：A new type of polymeric materials called microcellular plastics was first proposed in the early l980s. The materials are characterized with very small cell sizes (generally smaller than10μm in diameter) , uniform cell size distributions and very high cell densities (more than109cells/cm3). Now the process technologies of microcellular plastics have been successfully developed and various products have been commercialized. Microporous materials have got extensive applications for theirs interconnected porous structure. In this paper, different techniques for the preparation of porous polymer are overviewed. Necessity of applying microcellular foaming technology to form open-cell polymeric porous material is discussed. Various approaches of preparing open-cell polymeric porous material are presented such as immiscible polymer blending, bubble coalescence model, melting extrusion foam, pore opener method and gas concentration threshold. Different method adopts different forming mechanism and has different morphology of microstructure. It can be concluded that microcellular foaming technology is a very promising means to prepare open-cell polymeric porous material.

        摘要：In this paper, new development of polymeric ionic liquids has been reviewed. There are two classes supported materials of ionic liquids, one is inorganic polymer and another is organic polymer. The ionic liquids (ILs) can be bound to the silanol groups of surface of inorganic polymer by covalent bonds. In Friede-l Crafts reactions some of the novel catalysts show catalytic activities; highly conductive polymer electrolyte, prepared by ionic liquids and organic polymer, shows favorable application prospect.

        摘要：To extend PSRK model to describe polymer-solvent vapor-liquid equilibria (VLE) , the modified mixing rule for the parameter bis an exponent of 1/2 for the binary parameter bij. For pure polymers, a set of parameters (a/MWand b/MW) are employed to keep the parameters to be independent of molecular weight (MW). The PSRK model with modified mixing rule is applied to the prediction of VLE data for binary polymer solutions over a large rang of temperature and pressure with satisfactory results.

        摘要：In this paper, a temperature-strain curve tester for polymers by interval load method is introduced , which can accept parameters and collect data with the help of a personal computer. This equipment can be used in teaching work or research work to determine the linear or non-linear expanding behaviors of polymers , such as PMMA, to determine some characteristic temperature of polymers, such as Tgand Tf, or to do some research work on molecular motion analysis and get the related parameters. By interval load method, the changes of strain of a certain sample in an interval can be detected, thus the differences between being compressed and uncompressed are obviously found out. So the errors of constant method due to the thermal expanding of equipment itself and creep of polymers can be ruled out and then more reliable data can be provided. Being given the parameters of heating rate and intelval load, the universality of this temperature-strain curve tester for polymers is considerable.
