    摘要: The invention is for a process of removal of dissolved cation contaminants from a resin solution. The process of the invention involves providing a chelating ion exchange resin modified by treatment with an acid and contact of said solution with said modified exchange resin for a time sufficient to remove ionic metal impurities. The invention is useful for removal of ionic contaminants from resin solutions used in the preparation of photoresists.

    摘要: A resin suitable for use as a photoresist that is the esterification product of an o-quinonediazide compound and an aromatic novolak resin. The aromatic novolak resin may be the condensation product of a reactive phenol with a bis(hydroxymethyl)phenol or an aromatic aldehyde. The aromatic resin may be chain extended by further reaction with an additional aldehyde. The resin has a maximum of 20 percent of its phenolic hydroxyl groups esterified with the o-quinonediazide sulfonate compound.

    摘要: A photoresist comprising a light sensitive component and an alternating copolymer resin formed by condensing a preformed bishydroxymethylated compound and a reactive phenol, in the absence of an aldehyde. Additional useful resins may be formed by further reacting the alternating copolymer with a second reactive phenol in the presence of an aldehyde to form substantially block copolymers. The use of these resins in photoresist formulations leads to improved thermal properties, etch resistance and photospeed.

    摘要: Asymmetric gas separation membranes of materials having selective permeation of at least one gas of a gaseous mixture over that of one or more remaining gases of the gaseous mixture, exhibit significantly improved permeation selectivities for the at least one gas when the asymmetric membrane is contacted on one or both surfaces with an effective amount of a Lewis acid. The improved asymmetric gas separation membranes, process for producing the improved membrane, and processes utilizing such membranes for selectively separating at least one gas from a gaseous mixture by permeation are disclosed.

    摘要: A multicomponent membrane having improved permeation characteristics for separation of one gas from a mixture of gases by permeation of the one gas through the membrane. The membrane is in the form of a porous, anisotropic substrate membrane and a coating in contact with the substrate membrane, the coating being made of poly(dimethyl siloxane), containing 1 to 20 weight percent of a permeation-modifying radical selected from the group consisting of ##STR1## The coating is applied to the substrate in the form of a solution of 0.05 to 1 weight percent of the coating in a suitable solvent such as pentane.
