Azido-silane compositions

Claim 1

A solubilized azido-containing silane composition of matter produced by a process which comprises reacting in the presence of a non-aqueous solvent a. an azido-containing carboxylic acid halide of the formula (N.sub.3 X).sub.a --Ar--(R).sub.n --COHal wherein X is a radical selected from the group consisting of sulfonyl and formyl radicals, a is an integer of from 1 to 2, Ar is an aryl radical, R is a divalent alkylene radical having from 1 to 17 carbon atoms, wherein n has a value of 0 or 1; and Hal represents a halogen radical, with (b) an amino-containing silane having the formula ##EQU4## wherein R 2 is a monovalent hydrocarbon radical, b has a value of 0 to 2, Y is a hydrolyzable group selected from the class consisting of alkoxy and aryloxy radicals and wherein R' is an organic radical directly bonded to the silicon atom of said silane through a carbon to silicon bond, said organic radical further containing at least one nitrogen atom which has a hydrogen atom bonded directly to it, said solvent being present in an amount sufficient to solubilize the azido-containing silane product of (a) and (b).
