Zusammenfassung:	PURPOSE:To provide the titled composition composed of PP, mica treated with an organosilane compound, modified polyolefin, and glass fiber treated with an organosilane compound, and having high rigidity and excellent fluidity, shrinkage anisotropy, and retention of flexural strength at the weld part. CONSTITUTION:The objective composition is produced by compounding and kneading (A) a PP resin (preferably isotactic polymer, syndiotactic polymer, atactic polymer, etc. having a density of 0.89-0.92g/cm ), (B) mica treated with silane compound (preferably a compound having amino group, e.g. gamma-aminopropyltriethoxysilane), (C) a modified polyolefin [preferably polyolefin chemically modified with a liquid rubber (terminal hydroxylated polybutadiene) and/or an unsaturated carboxylic acid (including anhydride)], (D) glass fibers treated with an organic silane compound (preferably a compound containing amino group), and (E) other additives. EFFECT:Excellent appearance. USE:Material for various molded articles, especially for precision apparatuses.
