    摘要： A fluid reservoir for retaining a particular fluid against an environmental force is disclosed. The fluid reservoir includes a three dimensional porous body that has a plurality of reservoir capillaries formed therein and has a transport volume and effective capillarity in the force direction for the particular fluid when the porous body is oriented in a predetermined orientation. The fluid reservoir also includes at least one lateral indentation in a surface of the porous body. Each of the at least one lateral indentation defines opposing reservoir surfaces each having a lateral surface component orthogonal to the force direction. The at least one lateral indentation is configured so that at least a majority of the reservoir capillaries have a force-aligned length component that is less than the effective capillarity for the particular fluid.

    摘要： A method is provided for the production of 3,3', 4,4'-tetraaminobiphenyl (TAB) from biphenyl comprising the following steps:1) acetylating the biphenyl in the presence of an appropriate Friedel-Crafts catalyst to obtain 4,4'-diacetylbiphenyl (DAcB);2) oximating the DAcB to form DAcB dioxime;3) subjecting the dioxime to a double Beckmann rearrangement to obtain N,N-diacetylbenzidine (DiAcBz);4) nitrating the DiAcBz to obtain 3,3'-dinitro-N,N-diacetylbenzidine (DNAcBz)5) removing the acetyl groups of the DNAcBz by basic hydrolysis to form 3,3'-dinitrobenzidine (DNB); and6) reducing the nitrate groups of the DNB to form TAB.

    摘要： A two stage process for the production of polybenzimidazoles is provided wherein an aromatic tetraamine, e.g., 3,3',4,4'-tetraaminobiphenyl, is reacted with a dicarboxylic component consisting of at least one compound having the formula: ##STR1## in which R' is a divalent organic radical and may be the same or different in the various molecules making up the dicarboxylic component and the Y's may be the hydrogen, aryl or alkyl, with no more than 95% the Y's being hydrogen or phenyl. The reactants are heated with agitation in a first stage to a temperature above the melting point of the tetraamine until the viscosity of the mixture rises as indicated by an agitator torque of at least 1.5 times that before the rise in viscosity. The agitation is then discontinued and the reaction mixture is allowed to foam while heating is continued. The foam is then allowed to cool to a friable mass and is crushed to a ground prepolymer which is heated with agitation in a second stage until the desired polymer is obtained. The invention also includes certain benzimidazole polymers as new composition of matter.
