Publication number: 20110245388Abstract: In a polycarbonate resin composition containing a polycarbonate resin and a polycarbosilane compound, the use of the polycarbosilane compound modifies the surface properties of the polycarbonate resin composition without adversely affecting the intrinsic characteristics of the polycarbonate resin, such as transparency, heat resistance, and mechanical properties, e.g., impact resistance. A polycarbonate resin composition containing 100 parts by mass of a polycarbonate resin, 0.001 to 1 part by mass of a metal salt compound, and 0.005 to 5 parts by mass of a polycarbosilane compound has significantly improved flame resistance and high transparency and causes markedly reduced outgassing and mold fouling, without losing impact resistance and heat resistance.Type: ApplicationFiled: January 7, 2010Publication date: October 6, 2011Applicant: Mitsubishi Engineering-Plastics CorporationInventor: Toshiki Monden

Patent number: 7994255Abstract: The present invention relates to a flame retardant which is a graft copolymer. The graft copolymer is obtained by polymerizing a vinyl monomer containing at least two polymerizable groups, and at least one other vinyl monomer, in the presence of polyorganosiloxane particles in a latex state. The polyorganosiloxane particles contain grafting agents that are unevenly distributed on the surface thereof. The present invention also relates to thermoplastic resins containing this flame retardant.Type: GrantFiled: April 9, 2004Date of Patent: August 9, 2011Assignee: Kaneka CorporationInventors: Tomomichi Hashimoto, Akira Takaki, Kazunori Saegusa, Takao Manabe, Takao Michinobu
