Abstract
The invention is directed to water soluble silane compositions that are essentially alcohol free comprising compounds of the structure: (RO).sub.3-x (HO).sub.x Si(CH.sub.2).sub.3 (OCH.sub.2 CH.sub.2).sub.b OH(Ia ) {(RO).sub.2-y (HO).sub.y Si(CH.sub.2).sub.3 (OCH.sub.2 CH.sub.2).sub.b O}.sub.z (IIa) wherein x ranges from 1 to 3, b ranges from 1 to 30, y is 0 or 1, and z ranges from 1 to 3, and R is an aryl or alkyl having from 1 to 10 carbon atoms. The invention further comprises methods for forming such compounds and for their use in preparing water soluble silane compositions by reaction with relative insoluble silane compounds terminated in functional groups selected from the group comprising epoxies, vinyls, mercaptos and acrylates.
