Abstract
This invention relates to the preparation of a partially quaternized ammonium organosilane composition, and a self-stabilizing aqueous solution of said composition, which serves to yield an antimicrobial polysilsesquioxane coating upon thermal curing. By way of this invention, an aqueous solution is prepared, comprised in part by a partially quaternized ammonium organosilane hydrolysate, characterized in that no further manipulation or addition of potentially costly ingredients are required to yield a stable and hence marketable product.

A method to synthesize an organosilyl quaternary amine composition of the type CH3(CHa)11-17(CH3)2N+(CH2)1-6Si(Z)3 X− the method comprising the steps of:
- preparing a two-component composition, comprising:
- CH3(CHa)11-17N(CH3)2 and X(CH2)1-6Si(Z)3 precursor materials, combined in a CH3(CHa)11-17N(CH3)2/X(CH2)1-6Si(Z)3 molar ratio of 0.85-1.5;
- and terminating the process at a product conversion corresponding to a yield of 45 to 65%, with respect to the limiting reagent.
A method to synthesize an organosilyl quaternary amine composition of the type CH3(CHa)11-17(CH3)2N+(CH2)1-6Si(Z)3 X31 by preparing a two-component composition, comprising of CH3(CHa)11-17X and (CH3)2N(CH2)1-6Si(Z)3 precursor materials, combined in a CH3(CHa)11-17X/(CH3)2N(CH2)1-6Si(Z)3 molar ratio of 0.85-1.5, wherein the process is terminated at a product conversion corresponding to a yield of 45 to 65%, with respect to the limiting reagent.
