Components (A-1) and (A-2) are employed in quantities such that from 10 to 75 weight percent of the diglycidyl ethers contained in component (A) are contributed by component (A-1), and from 25 to 90 weight percent of such glycidyl ethers are contributed by component (A-2). Components (A) and (B) are employed in such quantities that the resultant epoxy resin has an average epoxide equivalent weight of from 350 to 10,000.The terminal oxirane groups in the thus formed advanced epoxy resin are converted to cationic groups by reacting the resin with a nucleophilic compound and adding an organic acid and water at at least one point in the reaction. Process for the preparation of these advanced epoxy cationic resins is also disclosed.Advanced epoxy cationic resins of this invention are employed in the preparation of coating compositions suitable for electrodeposition.

摘要： A System to convert and dispense pressurized gas(es) of cryogenic liquids of gas(es), and systems and methods using a sphere pressure vessel to efficiently convert liquid natural gas (LNG) to compressed natural gas (CNG) and low pressure natural gas (NG) and other cryogenic liquids of gas. The system requires one dedicated sphere pressure vessel at the dispensing location and the location of elements according to horizontal and vertical orientation to convert, retain, store, and dispense multiple pressures of gas from a cryogenic liquid supply such as a non-dedicated high pressure cryogenic personal supply tank. The system efficiently modifies and controls parameters of volume, pressure, and temperature in conversion scale to retain all converted product under human control to dispense, without process required waste, for use in commercial, utility and industrial uses, and scaleable for single family residential applications where service can be accomplished by pickup truck and trailer, where semi trucks access is not available.

摘要： A polymer composite comprising a hydroxy-phenoxyether or polyester polymer matrix having dispersed therein layers of an inorganic material derived from a multilayered inorganic material having organophilic properties. The dispersion of the multilayered inorganic material in the polymer matrix is such that an increase in the average interlayer spacing of the layered inorganic material occurs. This increase in interlayer spacing occurs to a significant extent resulting in the formation of a nanocomposite. The polymers are preferably derived from a diglycidyl ether or ester or an epihalohydrin and a dinucleophile such as a dicarboxylic acid, a difunctional amine, a bisphenol or a sulfonamide. As the organophilic inorganic material clay minerals modified with organic ammonium compounds are used.
