热塑性/热固性聚合物共混体系研究——乙炔端基砜/聚砜共混物的动态固化动力学

The dynamic cure kinetics of thermosetting acetylene-terminated sulfone (ATS) and two blends prepared by the ATS and thermoplastic bisphenol A polysulfone (PSF), polyary-lethersulfone with cardo group (PES-C) were determinated by differential scanning calori-metry (DSC). The addition of polysulfone's resin increases the temperature of initial reaction and decreases the activation energy of cure reaction(E), pre-exponnential factor (LnA), and heat of cure reaction (AH). The temperature of reaction peak and final reaction and the reaction order(n) have been no effect.     

一种新型侧链液晶聚合物的喇曼光谱研究

The Raman scattering on a novel liquid crystal side chain polymer, poly-2,5-bis (p-meth-oxybenzoyloxy) styrene, has been performed. We observed that the characteristic Raman sp-ctra of the vinyl group in the monomer changed much deeply in the polymer, especially for the Raman line correponding to the C=C of the vinyl group which disappeared completly in the polymer. Contrast with that, the Raman spetra of the rest group did not present any substantial difference between the monomer and the polymer. These experimental facts show-ed that the vinyl group of the monomer was tranfered to the polymeric backbone while the chemical structure of the mesogenic unit in the monomer remained after the polymerization,and also conformed that it was successful in the synthesis of a liquid crystal side chain plymer without a flexible spacer between the mesomorphic unit and the molecular main chain.     

Synthesis and Crystal Structure of a Co（II） Coordination Polymer Derived from a Flexible Bipyridyl Derivative Ligand

1 INTRODUCTION The infinite networks constructed from transition metal complexes have attracted considerable current interest in recent years. The motivation behind this activity has been stimulated by their potential appli- cations in selective inclusion of ions, molecular re- cognition, host-guest chemistry, ion exchange, cata- lysis, electrical conductivity, magnetism, optics and so on[1～4]. It is well known that the diversity in structures and topologies of supramolecules is attri- b…

有机硅耐磨透明涂层的固化分析

ＦＴＩＲ、ＴＧ、ＴＢＡ等对有机硅耐磨涂料（有机硅溶胶）的热固化过程研究表明有机硅胶体中缔合羟基间的脱水缩合速率很高；羟基脱水程度与固化温度有关，温度越高，达平衡时羟基的浓度越低，在１０５～１３０℃间羟基的浓度变化最大，加入适当的固化剂，对羟基的脱水交联有促进作用，在较高的固化温度下，反应体系中出现了环氧环异构化产生的酮羰基的吸收峰
