Abstract
Abstract Filamentous glass in which the filaments are sized with non-burning or self-extinguishing polymeric compositions reinforce the physical properties of organic polymeric substances and impart a degree of flame retardance to glass-resin composites greater than that expected from the sizing content. There are provided molding compositions and injection molding granules containing resins and dispersions of such reinforcements and non-burning or self-extinguishing three-dimensional articles comprising resins containing such reinforcements.
