    Abstract: Cellulose fabrics, e.g. cotton, are crease-proofed by treating them with a solution or dispersion of an epoxy-functional silicon compound of the formula , or in which R and R1 are aliphatic hydrocarbon radicals containing less than 4 carbon atoms, n is 2 or 3, m is 2 or 3, x is 0, 1 or 2, a + b = 1, a is greater than 0 and not more than 0.5 and b is at least 0.5 and less than 1 and then curing the silicon compound by heating to 200 DEG -500 DEG F. for 1-60 minutes. The silicon compound may be applied to the fabric dissolved or emulsified in water or toluene with or without catalytic amount of a metal salt of an acid having a pKa value of less than 3.5 such as zinc, magnesium, aluminium, copper, nickel, cadmium, lead and mercuric fluoroborates and hydrates of such salts and metal perchlorates, sulphates and nitrates, by padding, dipping, rolling or spraying, and the fabric then dried and heated to 200 DEG -500 DEG F. for 1-60 minutes to effect curing. The epoxy silicon compounds may be applied in conjunction with other organo-silicon emulsions e.g. hydroxylated dimethyl siloxane and methyl hydrogen siloxane, to water proof the fabrics. Specifications 680,265, 686,212, 746,307, 755,028, 755,949, 766,864, 802,540, 831,020, 835,516 and 862,469 are referred to.

    Abstract: An organosilicon compound having attached to at least one Si atom by a Si-C linkage at least one organic radical containing at least one epoxide group, any remaining valencies being satisfied by hydrocarbon, halohydrocarbon, hydrocarbonoxy, halohydrocarbonoxy or hydroxyl radicals, or hydrogen or oxygen atoms, is made by heating a mixture of an unsaturated organic compound containing at least one epoxy group and a silicon compound containing at least one SiH group. The products are either silanes of the formul AxSiX4-x and AmRnSiX4-n-m or siloxane polymers or copolymers of the formula AmRbSiO4-m-b, wherein R is hydrogen, a hydrocarbon or halogenated hydrocarbon radical, X is a hydrocarbonoxy or hydroxyl radical, A is an epoxy or epoxidized radical, x is 1 to 4, m and n are each 1 to 3 and b is 0 to 2. The compounds may be cured by reacting them with conventional epoxide curing catalysts. In typical examples: (1) allylglycidyl ether was reacted with a mixture of tetramethyldisiloxane and toluene containing a diethyleneglycoldimethylether solution of chloroplatinic acid to yield on fractionation and and (2) vinylcyclohexenemonoepoxide was similarly reacted with [CH3.H.SiO]5 to give which cured with m-phenylenediamine into a hard, tough, heat-stable resin. Uses.-The compounds can be formed into cured mouldings, castings and films; used for coating metals and glass; used as adhesives; incorporated into epoxy, alkyd, aminoplast and polyamide resins and other siloxanes containing functional groups, these modified products being useful as lubricants, coating compositions, casting resins and paints; and can be used as intermediates in making organic-modified silicon compounds by reaction of the epoxide group, e.g. with water, HCl, HNO3, carboxylic acids, NH3 and amines, HCN, Na2SO3, phenols, Grignard reagents, alcohols, aldehydes and ketones, H2S, H3PO4 and with mercaptans, to yield respectively a glycol, a chlorohydrin, a hydroxynitrate ester, hydroxy esters, hydroxyl amine, cyanohydrins, hydroxy sodium sulphonate, hydroxy phenyl esters, hydroxy alcohols, hydroxy ethers, acetals, hydroxy thiols, hydroxy phosphate esters and hydroxy thioethers. The epoxy group may also be reduced to yield alcohols. These derivatives can be used as emulsifiers, plasticizers for organic and organosilicon resins, as lubricants, as intermediates in making organosilicon resins and as modifiers for organic resins.

    Abstract: Novel ionomeric silane coupling agents are disclosed and their use in bonding a matrix polymer to a mineral substrate is described. The coupling agents comprise amic acid-functional silanes which are partially neutralized with metal cations and are prepared by reacting a mixture of (I) an amine-functional silane, (II) a stoichiometric excess of a dicarboxylic organic acid and (III) an ionic compound containing a metal cation, wherein 10% to 80% of the excess carboxylic acid functionality is neutralized by the metal cations. The coupling agents greatly improve bonding to the matrix polymer in moist environments and are particularly suitable for use in formulating filled injection molding compositions.
