Manufactured by Dostrand. Each of these strands (solid content 1.0% by weight derived from the isizing agent for glass fibers) was mixed into a copolymer resin of acrylonitrile and styrene to contain 20% by weight of glass fibers. A pellet containing glass fibers was prepared by dispersing and mixing, and then a test piece was prepared by injection molding. The material III of each obtained test piece was measured according to the following ASTM method: Tensile strength...ASTM-D63
