标题 :Synthesis and polymerization of vinyl triazolium ionic liquids
发明人：LUEBKE DAVID; NULWALA HUNAID; MATYJASZEWSKI KRZYSZTOF; ADZIMA BRIAN
权利人:US ENERGY; THE US DEPARTMENT OF ENERGY
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.

标题:Synthesis of thioether containing trialkoxysilanes

权利人:GARRELL ROBIN L; TUCKER-SCHWARTZ ALEXANDER K; UNIV CALIFORNIA
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.

标 题 :Process for preparation of dithiols
发明人：ARRETZ EMMANUEL
权利人:ELF AQUITAINE
摘要:The invention relates to the synthesis of dithiols and more particularly that of alpha , omega -dithiols having 5 to 20 carbon atoms. The process according to the invention comprises reacting a di-(tertiary-alkylthio)alkane with hydrogen sulphide in the presence of a solid acid catalyst. The alkane dithiol is obtained selectively and a tertiary-alkyl mercaptan is obtained as by-product. It is possible to reuse the latter in a cyclical process to produce the original di-(tertiary-alkylthio)alkane.

标 题 :Reactive hyperbranched polymers for powder coatings

权利人:HERBERTS GMBH
摘要:Novel powder coating compositions containing reactive hyperbranched polymers are disclosed and claimed. Preferred embodiments include powder coating compositions formed from hyperbranched polyesters having terminal hydroxy, carboxy, epoxy, and isocyanate groups. Preferred hyperbranched polyesters are formed from alpha , alpha -bis-(hydroxymethyl)-propionic acid, which act either as crosslinkers, adhesion promotors, or flow and leveling agents. A process for the synthesis of powder coating compositions is also disclosed which involves (a) self condensation of one or more of the multifunctional monomers to form the hyperbranched polymer, optionally, in the presence of suitable reactive end-capping moieties which are described herein; (b) melt blending of the hyperbranched polymer with suitable amounts of one or more of polyesters, epoxy resins, blocked urethane resins, or acrylic resins, a crosslinker, and one or more of suitable additional ingredients including degassers or flow and leveling agents, to form a flake; and (c) grinding and sieving of the flake to form the powder coating composition. These compositions exhibit improved flow and curing properties. These compositions can therefore be formed into thin films and can be cured at low temperatures to form smooth surfaces. Additionally, these films are hard and exhibit enhanced impact resistance properties than the conventional polyester resins. Thus, these powder coating compositions find utilities in automotive, packaging, and appliances.
