The preparation process of self-holing polyimide with organosilicon block includes the following steps: 1 the first reaction of polyacid anhydride in functionality not lower than 2, silicon oil with 2 or more amino or imino groups and polyamine with 2 or more amino groups, and the second reaction with one or several kinds of added isocyanate with 2 or more isocyanate radicals to produce sol of polyamido acid containing organosilicon block; 2 solidifying the sol to obtain solid polyamido acid containing organosilicon block; and 3 imidonating the solid to obtain self-holing polyimide with organosilicon block.

本发明公开了一种有机硅嵌段自发孔聚酰亚胺的制备方法，该方法包括以下步骤：(1)有机溶剂中具有大于或者等于2的酸酐官能团度的多酸酐与具有大于或者等于2的胺基或亚胺基的硅油以及具有大于或者等于2的胺基的多胺反应，随后添加一种或多种具有含有等于或者大于2个异氰酸酯基的异氰酸酯反应，生成含有机硅嵌段聚酰胺酸的溶胶。(2)溶胶固化制成有机硅嵌段聚酰胺酸固体。(3)固体亚胺化，即得有机硅嵌段自发孔聚酰亚胺。

The bismaleimide has the defects such as high melting point, bad resolvability, high curing temperature, great brittleness because of the structure, and these restrict its application and development.

双马来酰亚胺由于结构的特点，使得双马来酰亚胺树脂具有熔点高、溶解性差、成型温度高、固化物脆性大等缺点，这些均限制了双马来酰亚胺树脂的应用与发展。

Fluorescent instruments.the colonies of the specimens yielding growth were identified by the vitek32 instruments and kb method was used for the drug sensitivity tests.results three hundred and thirtyone bacteria strains were isolated from a total of 3104 blood culture specimens,with a positive rate of 10.7%.of the identified bacteria,g+ cocci accounted for 50.3%,g-bacilli accounted for 44.7%,fungi accounted for 3.0%,and anaerobian accounted for 1.1%.the susceptibility rates of g-bacilli to imipenem,amikacin and cefoperazone/sulbactam were high.the susceptibility rate of g+ cocci to vancomycin and imipenem were also high.conclusion g+ cocci prevail over g-bacilli in the blood specimens.the staphylococci are the chief bacteria in the childrens blood specimens.both g+ cocci and g-bacilli are sensitive to imipenem.

Treatment of dials with N-tert-butanesulfinamide, all biaryl dials were successfully converted into the corresponding bis-imines which were then treated with samarium diiodide to afford diamine products. The absolute configurations of all the intramolecular coupling products were determined by X-ray crystallography.

轴手性二醛与N-叔丁基亚磺酰胺缩合得到相应的亚胺，其为一对非对映异构体。N-叔丁基亚磺酰亚胺在二碘化钐条件下得到的偶联产物，经X-衍射也确定了其立体构型。

Two new active esters of acrylic acids monomers, N-p-acryloxybenzoyloxy succini-mide and N-p-methacryloxybenzoyloxy succinimide have been synthesized and polymerized.ABOSu and MBOSu were prepared by coupling of p-acryloxybenzoic acid or p-methacryloxybenzoie acid with N-hydroxy succinimide in the presence of dicyclohexylcarbodimide.

Based on the-references on the thermal imidization of polyand the polymer composition analysis,the thermal imidization mechanism of SMA with aniline was demonstrated to be a two-stage consecutive reaction,in which a second-order reversible ring-opening reaction of SMA to produce poly(styrene-co-N-phenyl-maleamic acid)and a first-order irreversible intrachain ring-closing reaction to form SNPMI were involved.

论文首先参考聚酰胺酸热环化反应，并通过SMA酰亚胺化产物的组成分析，确定了SMA与苯胺的热酰亚胺化反应机理为一个包含由SMA生成苯乙烯—N-苯基马来酰胺酸共聚物的二级可逆开环反应以及由SNPMA生成苯乙烯—N-苯基马来酰亚胺共聚物的一级不可逆分子内闭环反应在内的串联反应过程，其中第二步SNPMA闭环反应为控制步骤。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
