Patent number: 6605655Abstract: Provided is a polyamide resin composition comprising a melt blend of (A) a polyamide resin, (B) a phyllosilicate, and (C) an olefin compound having a carboxylic acid anhydride group in the molecule or a polymer of the olefin compound, in which the phyllosilicate (B) has a reactive functional group bonded thereto and is such that the exchangeable metal ions existing in the inter layers are ion-exchanged with organic onium ions. The composition has a reduced inorganic ash content and has both high stiffness and high ductility. Optionally, the composition contains an inorganic filler apart from the phyllosilicate, an impact modifier, and a flame retardant, still having high stiffness and high ductility.Type: GrantFiled: March 29, 2000Date of Patent: August 12, 2003Assignee: Toray Industries, Inc.Inventors: Koya Kato, Toru Nishimura, Toru Yamanaka

Patent number: 6602933Abstract: In-organic fillers are modified by in-situ co-polymerization of vinyl silane and another vinyl monomer. Vinyl silane couples with the filler by Si—O bonds. The remaining vinyl groups on the surface of the treated fillers then co-polymerize with the other vinyl monomer. The modified in-organic fillers treated by the in-situ co-polymerization are subsequently used to fill the polymer matrix. Tensile and impact strength of filler-reinforced polymer composites are improved remarkably.Type: GrantFiled: October 5, 2001Date of Patent: August 5, 2003Assignee: The Hong Kong Polytechnic UniversityInventors: Chak Yin Tang, Xiao-lin Xie
