ABSTRACT:
A composite particulate material for resin reinforcement which comprises an inorganic particulate material (A) and an elastic polymer (B) having a glass transition temperature of -10.degree. C. or below and also having functional groups capable of forming chemical bonds with resins to be reinforced, said components (A) and (B) accounting for 50-99 wt % and 50-1 wt %, respectively, of their total amount. A process for producing said composite particulate material. A reinforced resin composition incorporated with said composite particulate material. The resin composition yields molded articles which are improved in mutually contradicting properties (that is, impact strength vs. stiffness and elongation at break vs. heat resistance) and which have mechanical properties with less anisotropy. It offers good characteristic properties which are hardly attained by conventional engineering plastic materials.
