Abstract
Chemically treated glass fibers having good processability are useful in producing fiber reinforced polymeric matrices, wherein the glass fibers have controlled wettability and are not detrimental to the weatherability of the fiber reinforced polymeric matrices. The chemically treated fibers have the dried residue of an aqueous chemical treating composition having a bisphenol A polyester film forming polymer compatible with and soluble in the matrix polymer, poly(vinyl acetate) polymeric film former, acryloxy-containing or methacryloxy-containing organo coupling agent in an effective coupling agent amount, cationic fiberous lubricant in an effective lubricating amount, with or without a cationic organic quaternary ammonium salt having alkoxy moieties, and with water in an amount to give a total solid for the aqueous chemical treating composition in the range of about 1 to about 30 weight percent. In addition, the aqueous chemical treating composition can have one or more amino-containing organofunctional silane coupling agents. The amount of the organic quaternary ammonium agent generally is in the range of from 0.05 to around 0.4 weight percent of the aqueous chemical treating com…
