    Abstract: A substituted cellulose ester having a cellulose backbone with an organic ester substituent and an inorganic ester substituent derived from the inorganic ester oxoacid catalyst may be utilized in adhesive compositions and articles produced therewith. Producing a substituted cellulose ester may, in some embodiments, involve providing a cellulose ester mixture that comprises a cellulose ester and a solvent; and hydrolyzing a mixture that comprises the cellulose ester mixture, water, and an inorganic ester oxoacid catalyst so as to yield a substituted cellulose ester having a cellulose backbone with an organic ester substituent and an inorganic ester substituent derived from the inorganic ester oxoacid catalyst.

    Abstract: The present invention is for crosslinked membranes and in particular for crosslinked poly(ethylene oxide)-cellulose acetate-silsesquioxane (PEO-CA-Si) organic-inorganic hybrid membranes and their use in gas separation. These crosslinked PEO-CA-Si membranes were prepared by in-situ sol-gel co-condensation of crosslinkable PEO-organotrialkoxysilane and CA-organotrialkoxysilane polymers in the presence of acetic acid catalyst during the formation of membranes. The crosslinkable PEO- and CA-organotrialkoxysilane polymers were synthesized via the reaction between the hydroxyl groups on PEO (or on CA) and the isocyanate on organotrialkoxysilane to form urethane linkages under mild conditions. The crosslinked PEO-CA-Si membranes exhibited both increased selectivity of CO2/N2 and CO2 permeability as compared to a CA membrane, suggesting that these membranes are very promising for gas separations such as CO2/N2 separation.

    Abstract translation: 本发明涉及交联膜,特别是交联聚(环氧乙烷) - 醋酸纤维素 - 倍半硅氧烷(PEO-CA-Si)有机 - 无机混合膜及其在气体分离中的应用。 这些交联的PEO-CA-Si膜通过在形成膜期间在乙酸催化剂存在下通过可交联的PEO-有机三烷氧基硅烷和CA-有机三烷氧基硅烷聚合物的原位溶胶 - 凝胶共缩合制备。 通过PEO(或CA)上的羟基与有机三烷氧基硅烷上的异氰酸酯之间的反应合成可交联PEO-和CA-有机三烷氧基硅烷聚合物,以在温和条件下形成氨基甲酸酯键。 与CA膜相比,交联的PEO-CA-Si膜显示出增加的CO 2 / N 2和CO 2渗透性的选择性,表明这些膜对于气体分离如CO 2 / N 2分离是非常有希望的。
