    摘要： High flux semipermeable membranes which comprises the polymerized reaction product within and/or on a porous support backing material may be prepared by contacting the porous support such as a polysulfone with an aqueous solution of a polyamine which may, if so desired, contain a polar aprotic solvent not reactive with the amines, a polyhydric compound and an acid acceptor. The surface of the coated support is freed of excess solution and thereafter contacted with an organic solution of a polyacyl halide for a period of time sufficient to form a polymerized reaction product within and/or on the support material. The resulting composite is then treated with a hydroxy polycarboxylic acid, polyaminoalkylene polycarboxylic acid, suffonic acid, amine salts of acids, amino acid, amino acid salt, polymeric acid and inorganic acid, before drying of the membrane. This will enable the membrane to be stored in a dry manner prior to use thereof in a separation process. The resultant membrane composite may be used in separation processes such as desalination of brackish or sea water or the softening of domestic hard water.

    摘要： A high solids, organic solvent based, sprayable coating composition which is capable of acid catalyzed crosslinking is composed of an active hydrogen-containing resin, a curing agent present externally and/or internally as a part of the active hydrogen-containing resin, and a catalytic amount of a non-ionic ester of a sulfonic acid. The sulfonic acid ester is represented by the following structural formula: ##STR1## wherein: Z is a radical selected from the group consisting of amino and an organic radical, said organic radical being connected to the sulfur atom by a carbon atom; ##STR2## C.sub.3 -C.sub.20 cycloalkyl; and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 are independently hydrogen or an organic radical. These groups can be particularly described as follows:R.sub.1 is hydrogen, carboalkoxy, C.sub.3 -C.sub.20 alkyl, C.sub.6 -C.sub.18 aryl, or C.sub.3 -C.sub.20 cycloalkyl;R.sub.2 is hydrogen, carboalkoxy, C.sub.3 -C.sub.20 alkyl, C.sub.6 -C.sub.18 aryl, or C.sub.3 -C.sub.20 cycloalkyl;R.sub.3 is hydrogen, carboalkoxy, acyloxy, N-alkylcarbamyloxy, N-arylcarbamyloxy, C.sub.3 -C.sub.20 alkyl, C.sub.6 -C.sub.18 aryl, or C.sub.3 -C.sub.20 cycloalkyl;R.sub.4 is hydrogen, carboalkoxy, acyloxy, N-alkylcarbamyloxy, N-arylcarbamyloxy, C.sub.3 -C.sub.20 alkyl, C.sub.6 -C.sub.18 aryl, or C.sub.3 -C.sub.20 cycloalkyl, andR.sub.5 is hydrogen, carboalkoxy, acyloxy, N-alkylcarbamyloxy, N-arylcarbamyloxy, C.sub.3 -C.sub.20 alkyl, C.sub.6 -C.sub.18 aryl, or C.sub.3 -C.sub.20 cycloalkyl.

    摘要： High flux semipermeable membranes which comprise a polymerized reaction product within and/or on a porous support may be prepared by contacting the porous support such as a polysulfone sheet with an aqueous solution of an polyamine, said aqueous solution containing a polar aprotic solvent not reactive with amines and optionally an acid acceptor. The surface of the coated support is dried to the touch and then contacted with an organic solution of an polycarboxylic acid halide for a period of time sufficient to form a polymerized reaction product within and/or on the surface of the support material. The resulting composite may be post treated by washing with an alkaline compound. The resultant membrane composite may be used in separation processes such as the desalination of brackish or seawater, or the softening of domestic hard water.

    摘要： A polymerizable ethylenically unsaturated urea urethane polymer dispersed in a polymerizable ethylenically unsaturated compound is prepared by a process which comprises reacting a polyisocyanate, at least a portion of which is a diisocyanate, with a polyfunctional amine containing primary and/or secondary amino groups in the presence of:(a) a polyol, at least a portion of which is a polymeric polyol containing ethylenic unsaturation and having a carbon to oxygen ratio of at least 4/1;(b) a diluent which is an ethylenically unsaturated compound free of active hydrogens; and(c) an active hydrogen containing polymerizable ethylenically unsaturated compound; under conditions sufficient to form a polymerizable ethylenically unsaturated urea urethane polymer dispersed in a polymerizable ethylenically unsaturated compound.The aforedescribed urea urethane polymer dispersions are particularly useful in formulating curable compositions suitable for use as adhesives and sealants.
