Styrenic (meth)acrylic oligomers that contain fewer terminal vinylic unsaturations demonstrate improved thermal stability and may provide improved resistance to UV weathering compared to the conventional and non-hydrogenated styrenic (meth)acrylic oligomers.Type: ApplicationFiled: September 30, 2011Publication date: April 5, 2012Inventors: Timothy D. Klots, Rafael Galvan, Jon Debling

Patent number: 8114947Abstract: The invention is a two part polymerizable composition comprising in one part an organoboron compound capable of forming free radical generating species amine complex and in the second part one or more compounds capable of free radical polymerization and a cure accelerator comprising a) at least one compound containing a quinone structure or b) at least one compound containing at least one aromatic ring and one or more, preferably two substituents on the aromatic ring selected from hydroxyl, ether and both, where there are two substituents they are located either ortho or para with respect to one another and a peroxide containing compound. The second part may further contain an agent capable of causing the organoboron compound to form free radical generating species upon contacting the two parts. The first part may further comprises one or more compounds capable of free radical polymerization. This facilitates formulating compositions that have commercially desirable volumetric ratios of the two parts.Type: GrantFiled: September 26, 2007Date of Patent: February 14, 2012Assignee: Dow Global Technologies LLCInventors: Gary L. Jialanella, Dean A. Johnson

Publication number: 20110112242Abstract: Disclosed are a production process of a dye polymer having a dye content of from 1 to 50 wt %, and the dye polymer and its use. The production process includes subjecting an addition-polymerizable monomer to living radical polymerization by using, as a polymerization initiator, a dye having a polymerization initiating group enabling the living radical polymerization. The dye polymer and a composition of the dye polymer and a pigment are useful as good coloring agents for various products or articles. The colored products or articles are high in transparency, and are provided with high added value. The dye polymer can also be used as a dispersant for pigments, thereby making it possible to afford pigment dispersions excellent in dispersion properties and dispersion stability.Type: ApplicationFiled: June 26, 2009Publication date: May 12, 2011Applicants: Kyoto University, Dainichiseika Color & Chemicals Mfg.Co., Ltd.Inventors: Hiroyuki Shimanaka, Toshiyuki Hitotsuyanagi, Yoshikazu Murakami, Atsushi Goto, Yoshinobu Tsujii, Takeshi Fukuda
