  solution of polymer
For V >amp;gt; Vc, sliding is homogeneous and friction is ruled by the shear-thinning rheology of an interfacial layer of thickness of order the (nanometric) mesh size, containing a solution of polymer chain ends hanging from the network.
      
Using k-ε model of turbulence and measured wall functions, turbulent flows of Newtonian (pure water) and a sort of non-Newtonian fluid (dilute, drag-reduction solution of polymer) in a 180-degree curved bend were simulated numerically.
      
The solution of polymer was dried as a film and then it was dissolved in DMSO.
      
In this process the dry active material and conductive carbon are mixed and then dispersed in a solution of polymer and solvent, NMP.
      
It involves sequentially dipping a substrate alternately into solutions containing species to be adsorbed and a solution of polymer.
      


In this paper, appling the selective intermolecular force, the authors have resolved satisfactorily the problems about the solubilities and the beat of solution of polymer, which could not be explained by Hildebrand's theory. It has been shown that the selective intermolecular force is one of the principle causes of the unknown specific interaction between solvent and polymer, described by Dwyer and Karim as well as other investigators, it is considered by authors that the extensive investigations...

In this paper, appling the selective intermolecular force, the authors have resolved satisfactorily the problems about the solubilities and the beat of solution of polymer, which could not be explained by Hildebrand's theory. It has been shown that the selective intermolecular force is one of the principle causes of the unknown specific interaction between solvent and polymer, described by Dwyer and Karim as well as other investigators, it is considered by authors that the extensive investigations of the selective intermolecular force are necessary and important for a better understanding of many specific of polymer solution.

本文以选择性分子间引力论述了高分子的溶解、溶解热等问题,阐述了Hildebrand等建立的混合热理论所未能预测的一些事实;同时讨论了Dwyer等所提出的溶质和溶剂间的特殊相互作用力,认为高分子和溶剂间的选择性分子间引力是特殊相互作用力的重要内容。因为用选择性分子间引力,可以深入理解高分子和溶剂间的选择性本质,所以它对高分子溶液性质的研究是有意义的。

In this paper the synthesis of polyhexamethylene terephthalamide (PHTA)by low temperature polycondensation from terephthoyl chloride (TPC) and hexamethyleaediamine (HDA) in the amide-salts (NMP-LiCl-CaCl2) solvent system was studied. Triethylamine (TEA) was used as an acid acceptor. The homogeneous reaction solution of polymer with about 0.8dl/g (inherent viscosity) , which is available for the preparation of polymer film and fiber, can be obtained. The PHTA obtained was charactered by FTIR and DSC....

The hydrosilation adduct of [60]fulleropyrrolidine derivative(Ⅰ) with dichloromethylsilane in the presence of H\-2PtCl\-6\| i \|PrOH was polycondensed with silanol\|terminated dimethyl silicon oil ( M n=500) in a molar ratio of 1∶4 and then treated with excess chlorotrimethylsilane to obtain [60] fulleropyrrolidinepolysiloxane(Ⅱ). The polymer Ⅱ was characterized by 1 HNMR and FTIR and used as stationary phase for capillary chromatography for the first time. A fused silica capillary column was coated...

The hydrosilation adduct of [60]fulleropyrrolidine derivative(Ⅰ) with dichloromethylsilane in the presence of H\-2PtCl\-6\| i \|PrOH was polycondensed with silanol\|terminated dimethyl silicon oil ( M n=500) in a molar ratio of 1∶4 and then treated with excess chlorotrimethylsilane to obtain [60] fulleropyrrolidinepolysiloxane(Ⅱ). The polymer Ⅱ was characterized by 1 HNMR and FTIR and used as stationary phase for capillary chromatography for the first time. A fused silica capillary column was coated with a 0 25% solution of polymer Ⅱ in dichloromethane by the static method. The column efficiency is 2 800 plates per metre. The average polarity of the column, represented by the McReynolds constant, was 84 8, which was a little higher than that of SE\|30(43 4). The column showed good selectivity towards nitrogenous compounds and aromatic amines. For example, the capacity factors( k \+) for pyrrole, pyridine, piperidine and N \|methylpyridine (at 70℃) were 0 37,0 41,0 55 and 0 92 respectively and k\+ for o \|methylaniline, m \|methylaniline, N \|ethyl\| m \|methylaniline and N,N \|diethyl\| m \|methylaniline (at 110℃) were 1 55,1 74,3 86 and 6 02 respectively. It can well separate polyaromatic hydrocarbons (PAHs) due to the π\|π interaction of three\|dimensional π system of C 60 and PAHs. Phthalic diesters can be well separated on this column. The column also showed excellent thermostability. Column bleed was measured by programming the operating temperature from 250℃ to 360℃ at 4℃/min. The results showed that the column began to bleed at 300℃ and the baseline drift was 5fA at 360℃.

通过C60吡咯烷衍生物(Ⅰ)和甲基二氯硅烷的硅氢加成产物和端羟基甲基硅油缩合,合成了首例C60衍生物气相色谱固定相——C60吡咯烷聚硅氧烷(Ⅱ),并首次研究了它在毛细管气相色谱中的应用。结果表明,该固定相可有效分离多环芳烃,对高沸点的邻苯二甲酸二酯类化合物有很好的分离效果,且有很好的热稳定性,360℃时基线漂移量为5fA。
