Publication number: 20100311892Abstract: An object of the present invention is to provide an aid for filler-reinforced resins, a filler-reinforced resin composition comprising the aid for filler-reinforced resins, and a molded article formed from the filler-reinforced resin composition. The above aid for filler-reinforced resins is capable of improving reinforcing properties and dispersibility of the filler in the filler-reinforced resin composition, and when the filler-reinforced resin composition is formed into a molded article, the aid for filler-reinforced resins enables the molded article to have superior mechanical characteristics, such as an impact resistance and a flexural strength.Type: ApplicationFiled: November 26, 2008Publication date: December 9, 2010Applicant: MITSUI CHEMICALS, INCInventors: Akihide Mori, Hiroyasu Oochi
