ABSTRACT:
Chemically treated fibers have an aqueous chemical treating composition and are useful for reinforcing thermoplastic polymers most notably polyacetals and polyphenylenesulfide. The aqueous chemical treating composition has a water soluble silylazide in an effective coupling agent amount, and one or more stabilizing agents selected from a fortified film forming polymer present as an oil-in-water emulsion, an unsaturated organo-compound present in an amount to stabilize the reinforced matrix polymer from degradation by silylazide derivatives or additives, a water soluble polymer, like poly(vinyl alcohol) or silylated poly(vinyl alcohol) present in the composition in an amount greater than 10 weight percent of the composition and mixtures thereof, and water in an effective amount for application of the composition to the fibers. The polymer in the emulsion forms a film through evaporation of volatiles or through curing and is present in the emulsion in about 10 to about 80 weight percent total solids and is present in the aqueous chemical treating composition in an amount of at least around ten weight percent of the solids of the composition. The fortified emulsion has a fortifying amount of a nonionic surfactant, polyvinyl alcohol, silylated poly(vinyl alcohol), or mixture thereof. Additionally, a fiber lubricant can be present which is essentially free of any primary or secondary nitrogen containing moieties present in an effective lubricating amount.
