摘要： A heat-curable and solvent-soluble ester group-containing polymer composition is prepared by the steps of:(1) either (i) reacting a highly polymerized linear aromatic polyester with a diaryl carbonate to depolymerize it to a solvent-soluble low-molecular-weight polyester (component A) containing terminal aryl carboxylate groups, or (ii) effecting the above depolymerization in the presence of a compound containing at least two specified functional groups thereby to form a modified solvent-soluble low-molecular-weight polyester (component A') containing terminal aryl carboxylate groups; and(2) either (i) mixing the resulting component A or A' with a monomeric or solvent-soluble polymeric, polyfunctional compound (component B) containing at least two hydroxyl and/or primary or secondary amino groups or (ii) partially reacting the resulting component A or A' with the component B. The composition has superior workability in molding and curing, and gives cured molded products of high utilitarian value. It is especially suitable for use in wire enamelling varnishes.

摘要： A module comprising a plurality of members for obtaining a gas having a specified gas concentrated therein from a mixture of at least two gases, each of said members comprising (a) a solid support plate and (b) a composite film comprised of a porous sheet-like material and one or a plurality of ultrathin solid membranes supported on the porous sheet-like material with a thickness of about 50 to about 5000 .ANG.. This module is characterized in that(1) each of said members has a first gas drawing port for drawing off the gas having a specified gas concentrated therein, and the pressure drop in a passage for the concentrated gas in the members is not more than about 2 mmHg per cm in a direction away from the first gas drawing port,(2) the module has a common feed port for feeding the mixture of at least two gases to the solid membrane surface of each members, a second drawing port connected to the first gas drawing port of each of said members, and a third common drawing port for drawing off the remaining gases formed as a result of concentration by each of the members, and(3) in each of the members, the flow of the gaseous mixture is countercurrent, or angularly displaced, to the flowing direction of the concentrated gas.An oxygen enricher having the module is useful for obtaining an oxygen-enriched gas from air.
