    • Ethylene bridged benzylamine trifunctional silanes are provided having the general formula:Z--CH.sub.2 --Ph--CH.sub.2 CH.sub.2 --SiX.sub.3wherein Ph is a phenyl group, at least one X is a hydrolyzable group and Z is a non-hydrolyzable amine functional group. At least one X group is that which is displaced by hydrolysis during the well known reactions of silanes with siliceous substrates, and is preferably methoxy, ethoxy or methoxyethoxy. The Z group is intended to react and bond with polymers in the formation of polymer composites reinforced with siliceous substrates such as glass fibers. The Z group is preferably an amine or alkyl diamine group. The silanes of the invention have excellent thermal stability so that they may be used as coupling agents for composites in which the polymers are processed at temperatures in excess of 350.degree. C. and/or are subject to temperatures in excess of 150.degree. C. for extended periods of time.

    • A branched alkylsilane includes a branched hydrocarbon backbone which has a linear or branched alkylsilyl moiety extending asymmetrically from the backbone such that the backbone has a first portion and a second portion extending from the moiety. The second portion has two carbon atoms more than the first portion, and the alkylsilyl moiety includes at least one hydrolyzable group bound to silicon for reacting with a substrate. A method for preparing a branched alkylsilane useful for chromatographic applications includes the steps of preparing a vinylidene olefin by dimerization of an .alpha.-olefin and reacting it with a monomeric silane having a silicon-hydrogen bond in the presence of a metallic catalyst such that the silicon-hydrogen bond is added to the vinylidene double bond of the vinylidene olefin thereby converting the double bond to a single bond and bonding the silicon of the monomeric silane to the vinylidene olefin to form a branched alkylsilane.

    • Novel hydroxymethyltrialkoxysilanes of the formula: ##STR1## are produced by transesterifying a carboxylic acid ester of hydroxymethyltrialkoxysilane with an alcohol, and distilling the reaction mixture to remove the carboxylate of the alcohol. The carboxylic acid ester of hydroxymethyltrialkoxysilane is prepared by the reaction of an alkali metal carboxylate with chloromethyltrialkoxysilane, which in turn is prepared by the reaction of a trialkylorthoester with chloromethyltrichlorosilane by heating to reflux with removal of alkylchloride, followed by distillation to remove alkyl ester. The hydroxymethyltrialkoxysilanes and carboxylic acid esters thereof, as well as carboxymethyltrialkoxysilanes, are particularly useful in sol-gel processing by undergoing hydrolysis to yield hydroxymethylsilanetriol, and subsequent hydrolysis and polycondensation products.
