Abstract
Glass fibers are coated with a sizing composition comprising an aqueous emulsion based on at least one polyolefin having grafted thereon at least one acid or anhydride which is neutralized by at least one alcoholamine, at least one aminosilane coupling agent, and at least one primary, secondary or tertiary aliphatic monoamine stabilizing agent which is miscible with water and which has a pK.sub.b value lower than the pK.sub.b value of the amine group of the coupling agent, plus 1. The glass fibers of the invention are intended more particularly for reinforcing polyolefin matrices such as polypropylene matrices.
