摘要:The recent progress in plasma polymerization of fluorocarbons has been reviewed. The content includes; (1)plasma deposition mechnism of plasma fluorocarbons ; (2) structure characterization of plasma-polymerized fluo rocarbons mainly discussing the applying of XPS techniches; (3)the application fields of plasma-polymerized fluorocarbons.
摘要:Graft copolymerization of vinyl monomers onto flax and allied fibers (include jute, ramie and apocynum fibres) has received considerable attention in recent years. Various initiation systems have been used in the research field. The most important ones are: 1. Radiation initiation. 2. Photoinitiation. 3. Ce(IV ) ion initiation. 4.Permanagamte initiation. 5. V(V) ion initiation. 6. Fenton s reagent (Fe2+-H2O2) initiation. 7. Peroxydisulfate redox system initiation. All graft initiation methods as well as the characterization of structure and properties of grafted fibres have been reviewed in the paper.
摘要:New results and development trends of functional liquid crystalline membranes are reviewed. It is demonstrated that liquid crystalline membranes are more effective as. gas permselective, liquid perm selective membranes and a very large area light controllable film because of their excellent gas separation, liquid separation and controllable light intensity properties.

摘要:The recent development and new trends of poly-p-phenyl ene terephthalamide and their copolymer fibers are reviewed with 23 references. Some changes in research tendency, recent progress in technology, and the development in fiber variety and new market are disussed.
摘要:Through the description of silkworm's spinning organ, the constituents, morphology, chemical and physical properties of silk and tibroin are reviewed with emphasis on polymer science and the fibrosis mechanism of fibroin is discussed. The chemical grafts of silk and their applications are briefly described.
摘要:Synthesis of various kinds of macromonomers by using living anionic polymerization, living cationic polymerization, group transfer polymerization, radical polymerization and polycondensation has been reviewed and their characterization discussed. Recent progress about copolymerization of the macromonomer, purification and special properties of the copolymers with uniform grafts, including our works has been described.

摘要:This paper deseribes the concept of crystal-amorphous interphase and the technique such as SAXS, NMR, Laser Raman Spectroscopy which present the evidence for existence of the interphase in crystalline polymers. A review with 25 references on these field is given as well.
摘要:We first review briefly the definition and type of interpenetrating polymer net works. This will be followed by the relation of morphology with special properties of IPNs Systems. And brief the outline of a phenomenological theory of the phase stability. Finally we discuss recently developed of studies method of IPNs.
