Abstract
A sizing composition is provided that includes at least one silane satisfying the following formula: EQU Si(R.sup.1) (R.sup.2) (R.sup.3) (R.sup.4) wherein: R.sup.1 and R.sup.2 are each, independently, an alkoxy group; R.sup.3 is an alkoxy group or a hydrocarbon radical that optionally contains one or more nitrogens; R.sup.4 is a hydrocarbon radical that optionally contains one or more nitrogens, and includes at least one unsaturated ring substituted with at least one unsaturated chain conjugated with the unsaturated ring, that is useful for coating glass strands for reinforcement of organic or inorganic materials, the glass strands coated with such sizing compositions and the reinforced composite materials prepared therefrom, having mproved corrosion resistance, particularly in alkaline media.
