        摘要：This review covered the development and the major characteristies about the soluable coordination catalysts discovered by Kaminsky. Its meaning to the theory research of coordination polymerization had been described through recent research progress in the stereo-control mechanism of homogenous catalysis, the syndiotatic polymerization of α-olefins as well as the properties of polymeric active centers.

        摘要：This review is concerned particularly with the polymerization of vinyl and diene compounds in canal complexes formed by regular sheeted structure of steroidal compounds, such as deoxycholic acid (DCA), apocholic acid (apoCA) and cholic acid (CA). The historical studies on the polymerization, feature of the inclusion polymerization in DCA canals, characteristics of inclusion polymerization for comprehensive monomers, diacetylene, cyclic diene monomers and 2-chloroacrylonitrile, and asymmetric inclusion polymerization etc. were discussed in detail.

        摘要：New results and the frontier problems of the rheology of aromatic copolyesters in the liquid crystalline melts are reviewed. It is demonstrated that the copolyester liquid crystalline melts possess a lot of chararteristic rheological behaviour: exhibiting yield stress, lower viscosity, negative primary normal-stress difference, extra date contraction and longer relaxation time which markedly depend on shear rate (oscillatory frequency), temperature, time and thermal history.

        摘要：Authors have made a series of experiments and about ten related factors were examinad one by one. Acquiring a thorough and systematic understanding of the reaction regularity, then we preliminarily set up a basic theory system on the phosgenation interfacial polycondensation "one step method" . Theoretical and practical results show that a correct practice of the "one step method" has such adventages as good quality, high output and low consumption. And it is easy to realize continuation.

        Vol. 4, Issue 4, Pages: 242-253(1991) DOI: 10.14028/j.cnki.1003-3726.1991.04.009
        摘要：The preparation and characterization of the block copolymers of polysulfone were described in this paper. It was clearly of interest to investigate this area to establish structure-property relationships and the potential usefulness of such materials. It was reasoned that block copolymers prepared from such rigid amorphous engineering thermoplastics with a second crystalline segment would lead to vastly improved material performance. Such a system possessing an A-B-A (or A-B) structure in which the B represent a Polysulfone segment(PSF) and A represent crystalline segment e. g. PBT, N6,HQ-PSF etc. The presence of the crystalline segment should result in an overall enhanced solvent and stress crack resistance. The results show, that A-B-A(or A-B)block copolymers can be a compatible agent for polymer-polymer system and solvent-solvent system.
