  • Patent number: 9023914
    Abstract: A new process is provided for preparing nitrile rubbers by free-radical polymerization in an organic solvent and in the presence of specific modifier substances. This polymerization may be followed by hydrogenation to give likewise new hydrogenated nitrile rubbers, the hydrogenation advantageously taking place likewise in organic solvent. The optionally hydrogenated nitrile rubbers obtained are notable for having fragments of the employed modifier substances in the main polymer chain and/or as end groups. They can be prepared with a wide diversity of molecular weights and polydispersity indices, especially with very low polydispersity indices.

    Abstract: Through the use of an improved iron-based redox system it is possible to prepare special new, optionally hydrogenated, nitrile rubbers which feature a more uniform monomer distribution and a lower fraction of long-chain branches and hence are distinguished by enhanced flow properties at the same time as very good properties on processing.

  • Publication number: 20120329905
    Abstract: An optical copolymer comprising: a constituent derived from a sulfated lens monomer of general formula I [PG-R1—NHC(Y)S—R2]n—R3??I PG is a polymerizable group selected from the group consisting of vinyl, acryloyl, acryoyloxy, methacryoyl and methacryoyloxy; acrylamido and methacrylamido; Y is oxygen or sulfur; and n is 2, 3 or 4. Also, R1 is an organic group of one to eight carbon atoms and optionally with one or more oxygen atoms or an aromatic ring. R2 is a bond or an organic group of one to six carbon atoms. R3 is a bond, an organic group of one to ten carbons atoms, carbon, oxygen, sulfur or a disulfide; and a lens monomer. The sulfated lens monomer is derived from a first component of formula, PG-R1—NC(Y), and a polythiol of formula, R3—[R2—SH]n.

  • Patent number: 8318410
    Abstract: It is an object to provide a resist underlayer film forming composition having a selection ratio of dry etching rate larger than that of a resist film and exhibiting a low k value and a high n value at a short wavelength such as that of an ArF excimer laser, and enabling the formation of a resist pattern having a desired shape. When the composition is produced or used, it is required that odor due to a raw material monomer causes no problem. The object is solved by a resist underlayer film forming composition for lithography containing a polymer having in backbone thereof, a disulfide bond (S—S bond), and a solvent. The polymer may be a product of a reaction between at least one type of compound (diepoxy compound) containing two epoxy groups and at least one type of dicarboxylic acid containing a disulfide bond.

  • Publication number: 20120283351
    Abstract: A new process is provided for preparing nitrile rubbers by free-radical polymerization in an organic solvent and in the presence of specific modifier substances. This polymerization may be followed by hydrogenation to give likewise new hydrogenated nitrile rubbers, the hydrogenation advantageously taking place likewise in organic solvent. The optionally hydrogenated nitrile rubbers obtained are notable for having fragments of the employed modifier substances in the main polymer chain and/or as end groups. They can he prepared with a wide diversity of molecular weights and polydispersity indices, especially with very low polydispersity indices.
