摘要： Polyampholytes and their salts are used as scale and corrosion inhibitors, in drilling fluids and as a water oil ratio modifier in enhanced oil recovery. Novel polyampholyte polymers of intrinsic viscosity 0.05 to 4.5 in 1.0 M Na Cl are prepared from 20 to 90 weight % of a monomer of formula:
in which each R. which may be the same as or different from the other, is hydrogen, phenyl, C 1-3 alkyl or -COOX. R' is a straight or branched chain of from 0 to 12 carbon atoms, and X is hydrogen or an alkali or alkaline-earth metal; 1.5 to 85 weight % of a monomer of formula:
where each R 6 , which may be the same as or different from the other, is hydrogen, phenyl or C 1-3 alkyl, preferably hydrogen, methyl, or ethyl, and each R 2 , which may be the same as or different from the other, is hydrogen or C 1-3 alkyl; and 0.5 to 40 weight weight % of a cationic-containing monomer containing quaternary ammonium, phosphonium or sulfonium ion.

摘要： A water-insoluble electroconductive coating, which will allow subsequent coatings such as ZnO or dielectric resins to be applied from an aqueous-based system, is applied to a substrate as a double coating; a strong cationic polymer followed by a strong anionic polymer or vice versa. This results in the formation of a polysalt at the interface that is both water-insoluble and electroconductive.

摘要： Binary gas mixtures are separated on two carbon molecular sieve adsorbent beds to produce an enriched gas stream. This process includes the partial pressurization of an adsorbent bed with lean gas in the range of 40 to 90 percent of the adsorption pressure.
