摘要:In this paper,the synthesis of soluble conducting polymers was reviewed with emphasis on polyacetylene and its derivates. Their structure,property and recent development are also described
摘要:In this paper,the structure and the characteristics of microemulsion are explained generally. Some achivements in recent years about the microemulsion polymerization were summarized,especially on the inverse microemulsion polymerization of acrylamide, acrylate and (2 -methacryloyloxyethyl) trimethyl ammonium chloride in detail.
摘要:The synthesis structure and reaction mechanism of polymer Rhodium complexes for the carbonylation of methanol to acetic acid were reviewed. More over, it also reviewed the history of the production of acetic acid by' low pressure process' and development of foundmental theory.
摘要:In this paper a general review on the progress of modifying polymeric surface through UV - induced graft polymerization is presented. The methods of grafting, proof of grafting, structure of grafted film surface, experimental factors affecting photografting and wild applications of photoinitiated surface grafting are described.
摘要:Homogeneous Ziegler - Natta catalysts have been known since 1950s,but they have very low activities at that time. In 1980 it was found that using of oligomeric methylaluminoxane (MAO) as cocatalyst significantly increase the activity of the catalysts. The discovery made Ziegler - Natta catalysts in a state of renaissance and many new catalyst systems appear which can stereoselectively polymerize α-olefins and their derives. In this paper we present a review on the formation and development of homogeneous Ziegler - Natta catalysts.
摘要:The review with 82 refs. discussed the polymerization reaction rates, particle sizes,particle size distributions, particle numbers, molecule weights,molecule weight distributi ons, copolymer composition, latex stability and concentraction of surface groups and film properties in the semicontinuous emulsion polymerization . The effect of water soluble monomers on the semicontinuous emulsion polymerization and products were emphasized here.
摘要:Based on a brief introduction of Transparency - Opalescence Thermoreversible polymers,heat - sensitive property,synthesis,some application and outlook of poly (methyl) acrylamides occured in last decade are emphatically described.
