  An aqueous dispersible, isocyanate-containing polymer or prepolymer or chain extended polymer is provided which has internal pendant, reactable silane groups and which can also have internal dispersing aids. The aqueous dispersible, isocyanate-containing polymer, prepolymer, or chain extended polymer produces an aqueous dispersion of a polyurethane polymer having pendant reactable siliconate anions. The isocyanate-containing polymer is prepared from polyisocyanates, organic compounds with at least 2 active hydrogens, and organosilane which is at least monofunctional in reaction with isocyanate groups on at least one organic moiety of the organosilane. The organosilane also may have hydrolyzed or hydrolyzable groups associated with the silicone atom. The prepolymer is formed at temperatures less that 2000c at atmospheric pressure in a one shot or two step process. The polymer is combined with water to form an oil-in-water dispersion, and, if it is a prepolymer, the molecular weight is increased through chain extension. Th pH of the aqueous dispersion of the polyurethane is maintained at least around 7 when the silyl concentration of the polymer is greater than 0.1 weight percent of the water in the dispersion. The aqueous dispersion can also be prepared from a prepolymer that is devoid of any organosilane used as a comonomer and where the prepolymer is dispersed and chain-extended with the difunctional organo silane. The aqueous dispersion of the polyurethane resin is used in coating myriad substrates such as inorganic oxide substrates.

  Treated glass fibers having improved utilization of silane coupling agents are produced which have good strand handling and processing properties and which result in reinforced polymeric materials having good strength properties and good UV color stability. The treated glass fibers having an aqueous treating composition present on a substantial portion of the surface of the glass fibers, wherein the aqueous chemical treating composition has an aqueous dispersion of an internally silylated polyurethane polymer having siliconate anions and one or more dispersing agents in at least an effective dispersing amount, and water in an amount to give a total solids for the aqueous chemical composition for treatment of the glass fibers. The one or more dispersing agents, can be present as external dispersing agentes in which case their amounts could be both an effective dispersing amount and an effective lubricating amount. In addition, the dispersing agents can be present with the internally silylated polyurethane polymer as an internal hydrophific additive like nonionic and/or ionic and/or ionic precursor dispersing agents. In this case, the aqueous chemical treating composition has a glass fiber lubricant present in an effective lubricating amount. The internally silylated polyurethane may also have internal hardening segments to provide hardness to the polyurethane film formed on the glass fibers. The treated glass fibers can be used in reinforcing thermoplastic and thermosetting polymeric materials in various forms of continuous glass fibers and strand and chopped glass fibers and strands and mats of glass fibers and strands.
