Patent number: 7452958Abstract: Regioregular poly(3-alkylthiophenes) and other polythiophenes can be prepared by living polymerization which have good solubility, processability and environmental stability. The polymerization method can afford regioregular poly(3-alkylthiophenes) in high yields. Kinetic study of polymerization revealed the living character of this process. The molecular weight of poly(3-alkylthiophenes) is a function of the molar ratio of the monomer to nickel initiator, and conducting polymers with relatively narrow molecular weight distribution (PDI<1.5) are now readily available. Sequential monomer addition resulted in new block copolymers containing different poly(3-alkylthiophene) segments, which further confirms the “livingness” of this system. Other synthetic methods can be used as well to conduct living polymerization. Blends and electronic devices can be prepared.Type: GrantFiled: March 31, 2006Date of Patent: November 18, 2008Assignee: Carnegie Mellon UniversityInventors: Richard D. McCullough, Elena E.

Patent number: 7071280Abstract: Disclosed is an adhesive and a packaging laminate produced by using the same. The adhesive contains a polyisocyanate and a partially acid-modified polyol which is a product of reacting a polyol with anhydrotrimellitic acid and an anhydrotrimellitate ester at a ratio such that the anhydrotrimellitic acid is 10 to 70% by mass and the anhydrotrimellitate ester is 90 to 30% by mass, as the sum of the anhydrotrimellitic acid and the anhydrotrimellitate ester is 100% by mass. The packaging laminate has a first and second sheet-shaped substrates and the above adhesive through which the first and second sheet-shaped substrates are laminated.Type: GrantFiled: October 27, 2004Date of Patent: July 4, 2006Assignees: Toyo Ink Mfg.

Patent number: 7067566Abstract: Triazine ring based polymers for photoinduced liquid crystal alignment introduces photoactive groups for inducing, reinforcing, improving and preserving liquid crystal alignment, for example photoreactor such as cinnamate, coumarin, chalcone and maleimide, as a chain to have at least one photoactive group. One of the photoactive groups can experience Fries rearrangement which induces liquid crystal alignment, and other groups can experience photodimerization, photoisomerization, photocrosslinkng or photodegradation to reinforce, change or preserve the generated alignment.Type: GrantFiled: November 11, 2002Date of Patent: June 27, 2006Assignee: LG Cable Ltd.Inventors: Dongcheon Shin, Jinyool Kim, Kyusoon Park, Taemin Kim

Patent number: 7060758Abstract: A polyisocyanate compound obtained by highly converting a bis(isocyanatomethyl)cyclohexane into a uretidione compound, a process for producing the compound, a polyisocyanate polyaddition composition obtained by polyaddition of the compound, a compound having at least two hydroxyl groups and a compound having one hydroxyl group, and a powder coating material using the composition as the curing agent. The powder coating material is advantageous for safety and health due to the absence of dissociation of blocking agents and for economy due to a content of latent NCO greater than conventional uretidione-based powder coating materials.Type: GrantFiled: January 28, 2004Date of Patent: June 13, 2006Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Takeshi Koyama, Takeshi Nomura

Patent number: 4964146Abstract: Alignment in X-ray lithography is generally effected in such a manner that the surface of a target mark for alignment formed on a wafer is illuminated with light for alignment through an X-ray mask, and the position of the wafer is detected from the reflected light. On the basis of the finding that the reflected light from the mask, particularly from an absorber formed thereon, greatly degrades the precision and reliability in measurement, the present invention provides a pattern transfer mask provided with a thin film which lowers the reflection factor of the mask the thin film having a thickness set a .lambda./4n (.lambda.:the wavelength of the light for alignment; n: an integer) or an odd-number multiple thereof. Thus, it is advantageously possible to overcome the above-described lowering of precision and reliablity.Type: GrantFiled: March 15, 1989Date of Patent: October 16, 1990Assignee: Hitachi, Ltd.Inventors: Shinji Kuniyoshi, Takeshi Kumura
