摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

摘要:In particular, the invention relates to the synthesis of radiation-curable polyurethane/oligomeric urethane dispersions of anionic and cationic characters, containing neutralization techniques characterized by the selection of counter ions as monomers and/or agents which can be polymers acting as promoters under radiation, to a radiation polyurethane/oligomeric urethane synthesis method that enables the creation of radiation curable binder systems without using cosolvents, surfactants, emulsifiers, defoamers, stabilizers and additives, wherein all components of the radiation-curable binder systems can be polymerized.

标题:Initiator compositions and methods for their synthesis and use
发明人：CRIVELLO JAMES V
摘要:Cationic polymerization initiators of formula ##STR1## are disclosed. The acyl sulfonium salts of the present invention differ from known acyl sulfonium initiators in that the substituents R 2 and R 3 on the sulfur are larger and more complex than the lower alkyl and lower alkylene of known photoinitiators. Processes for the synthesis of the novel acyl sulfonium salts and prepolymer compositions containing them are also disclosed.

标题:Synthesis of thioether containing trialkoxysilanes

摘要:The invention relates to a radical-initiated thiol-ene or thiol-yne “clickâ€? reaction that provides a simple and efficient route to diverse trialkoxysilanes. Trialkoxysilanes made in this way are obtained in quantitative to near-quantitative yields with high purity without any or minimal purification. A wide range of functional groups is tolerated in this approach, and even complex alkenes click with the silane precursors. The modular nature of these radical-based thiol-ene or thiol-yne “clickâ€? reactions allows a wide variety of pendant groups to be coupled to silane compounds that can then be coupled to a wide variety surfaces in order to modify their material properties. Consequently, such radical initiated thiol-ene and thiol-yne reactions provide facile and efficient methods for preparing an enormous number of surface-active functional trialkoxysilanes.

摘要:A compound synthesis method includes bonding a first compound to a substrate to form a first film. A second film is formed on the first film using an acid-transfer composition including (A) a polymer that includes a structural unit shown by a following formula (1) and a structural unit shown by a following formula (2), (B) a photoacid generator shown by a following formula (3), and (C) a sensitizer shown by a following formula (4). The second film is exposed to remove the protecting group from the first compound under an exposed area of the second film. An acid generated in the exposed area of the second film is transferred to the first film. The second film after being exposed is removed. A second compound is bonded to the first compound from which the protecting group has been removed.

标题:Method of cleaving labile functional groups from chemical compounds
发明人：STENGELE KLAUS-PETER
摘要:The present invention provides a method of cleaving labile functional groups from molecules by exposure to electromagnetic radiation in which the molecules are contacted with a chemical compound whose triplet state is energetically higher than the triplet state of the labile functional group and are then exposed to electromagnetic radiation, with the labile functional group and the suitable chemical compound having different absorption maxima for electromagnetic radiation. Further, the invention provides a method of manufacturing DNA chips by spatially addressed, light-controlled nucleotide synthesis on solid substrates. In addition, the present invention provides a chemical composition comprising a molecule with a labile functional group and a chemical compound whose triplet state is higher than the triplet state of the labile functional group, with the labile functional group and the chemical compound having different absorption maxima for electromagnetic radiation, and describes the use of the chemical composition in the manufacture of DNA chips.
