Publication number: 20100273944Abstract: A thermoplastic resin composition includes a thermoplastic resin (A) and a reactive functional group-containing resin (B), which has a specific structure in the morphology of the resin composition observed by transmission electron microscopy tomography, and the relaxation time T1C of each carbon nucleus by the solid NMR measurement of the thermoplastic resin composition containing a polyamide resin is kept in a specific range. The composition is excellent in the balance between contradictory properties such as impact resistance and heat resistance, remarkably exhibits a peculiar viscoelastic behavior not observed in the conventional polymeric materials, and is remarkably excellent in impact energy absorbing performance and vibration energy absorbing performance at the time of high-speed deformation.Type: ApplicationFiled: March 22, 2007Publication date: October 28, 2010Applicant: Toray Industries, Inc., a corporation of JapanInventors: Sadayuki Kobayashi, Daisuke Sato, Masaru Akita, Hiroshi Jinnai, Takashi Inoue

Publication number: 20100251932Abstract: A method of modifying a particle that includes reacting a reactive compound having an X—[Y]n reactive group with a secondary compound N—S-ZM to form a substituted reactive intermediate [Y]a—X—(N—S-ZM)b, and reacting the particle with the substituted reactive intermediate [Y]a—X—(N—S-ZM)b to attach the substituted reactive intermediate to the surface of the particle to form a surface modified particle. The particle may comprise at least one of a dye particle, an inorganic pigment particle, an additive, or a combination thereof. X may be a sulfonyl, phosphoryl, or 1,3,5-triazinyl group. Y may be a halogen leaving group. N may be a nucleophilic group. S may be an organic group. ZM may be an ionizable end group. Also, n is an integer between 1 and 3, b is an integer between 1 and 3, and a=n?b. When n is equal to or greater than b, and wherein if b is 2 or 3, each N—S-ZM can be the same or different.Type: ApplicationFiled: April 7, 2010Publication date: October 7, 2010Inventors: Puthalath K.
