转化乳剂的离子电导和光电导研究

本文研究了ＡｇＢｒＣｌ转化乳剂的离子电导和光电导。随着乳剂中溴含量的增高，其离子电导也随之升高，而光电子寿命则降低。ＡｇＢｒＣｌ乳剂的离子电导主要取决于其组成；ＡｇＢｒＣｌ转化乳剂的光电子寿命主要受隙间银子浓度的影响，隙间银离子浓度越大，光电子寿命越短。

聚合转化率对硫调型氯丁胶结构与性能的影响

研究了硫调型氯丁橡胶乳液聚合中转化率对产晶结构与性能的影响.结果表明,随单体转化率的提高,聚合物的凝胶量及其交联密度增大,致使断链速度减慢,所得断链胶的门尼粘度上升,残存凝胶量增加,分子支化程度增大,分子量分布变宽,焦烧时间缩短。而相应硫化胶的拉伸强度、撕裂强度、冲击弹性和硬度等提高,扯断伸长率和永久变形下降。这些变化一般在转化率为80——85％时有明显转折.综合考虑产量与质量,聚合转化率控制在82±2％较为适宜。     

油水乳化液流变性研究进展

综述了油水乳化液流变性研究进展，介绍了目前国内外乳化液流变性的研究情况、乳化液的流变模式及乳化液流变性的评价方法。乳化液的剪切应力-剪切速率关系明显受油滴尺寸的影响，在含油量一定时，表观黏度随油滴尺寸的减小而增加。绝大多数乳化液在低剪切速度下(低于50s^-1)，呈现剪切变稀行为；在剪切速率超过1000s^-1时呈现牛顿行为。高含水原油的视黏度是温度、含水率以及剪切速率的函数。介绍了乳化液的3种流变模式，并给出了流变性评价方法实例。提出了油水乳化液流变性研究的发展方向。

Weathering modification of acrylic emulsion by introducing UV absorbing groups

A new kind of UV-absorbing silicon-fluorinated acrylic emulsion was prepared by emulsion polymerization with 4-allyloxy-2-hydroxybenzophenone, 3-methacryloxypropyltrimethoxysilane (MPS) and hexafluorobutyl methacrylate (HFMA) as functional monomers. The emulsion and its coating were characterized by transmission electron microscope, Fourier transform infrared spectrum (FTIR), X-ray photoelectron spectroscopy, ultraviolet absorption spectrum,thermo-gravimetric analysis, water contact angle (CA), and artificial accelerated aging test. The results indicated that the emulsion with core-shell structure was synthesized and showed prominent absorption peaks at 320 and 350 nm. The water CA of the coating was increased from 70.2° to 86.7° because of the incorporated HFMAs and MPSs. Both of the initial and final decomposition temperatures of the coating were increased by more than 20°C compared with those of the unmodified coating. After 10 days of accelerated aging, the color difference (ΔE) and rate of loss of gloss (ΔG) were only 2.78% and 5.22%, while those of the unmodified coating were as high as 22.94% and 78.57%, respectively. Because of the UV absorbers were incorporated by chemical reaction, the new coating had a more durable and effective anti-ultraviolet performance compared with the coatings the UV absorbers were introduced by physical blending.     

Kinetics of styrene emulsion polymerization with a stable monomer radical

We have analyzed the electrical conductivity of a linear high charge density polyelectrolyte aqueous solution, finding that the counterion association order follows the same pattern as that described for a cyclic monomeric polyelectrolyte, i.e. NO > Br^? > Cl^? > F^?. However, these counterions interact in a very different manner with this polyion, making Eisenberg's relationship inapplicable in this system. Consequently, an alternative method is proposed for treating data.
