Patent abstract
The present invention is directed to sizing compositions for glass fibers and glass fiber reinforced thermoplastic resins. The sizing composition comprises a maleic anhydride copolymer. Thermoplastic polyamide resin articles reinforced with glass fibers at least partially coated with a residue of the sizing composition can demonstrate a surprising improvement in strength of the reinforced polyamide resin when lubricated with a fatty acid metal salt and in the hydrolysis resistance when exposed to boiling water/ethylene glycol medium.
