The invention in particular relates to the synthesis of polymers by means of a mass polymerization. Said mass polymers have a significantly improved solubility in aqueous alkaline media over corresponding polymers produced by means of a heterogeneous aqueous polymerization method, such as emulsion or suspension polymerization. Improved solubility in said context refers to the dissolution rate being faster among particles of equal size, to no significant turbidity remaining after dissolution and to the viscosity of the obtained solutions being lower at the identical ratio of solids content. Furthermore, the compatibility of the compounds according to the invention with water-based varnishes is at least comparable or even improved.

    Abstract: The present invention describes the synthesis of new fluorinated elastomers with very low glass transition temperatures (Tg), a good resistance to bases, gasoline and other carburants and good workability properties, these elastomers contain hexafluoropropene (HFP), perfluoro(4-methyl-3,6-dioxaoct-7-ene) sulfonyl fluoride (PFSO2F), vinylidene fluoride (VDF) and/or at least one fluorinated alkene and/or one vinyl perfluorinated ether. In a precise case, they are prepared by radical polymerisation of HFP and PFSO2F or by radical terpolymerisation HFP, PFSO2F and VDF in the presence of different organic initiator, such as peroxides, peresters or diazo compounds.

  • Patent number: 7834113
    Abstract: The present invention relates to novel photoresist compositions and processes for preparing the same utilizing polymers having a low polydispersity via the use of certain chain transfer agents (CTA) with certain monomers to provide said polymers. The polymers incorporating the chain transfer agents can be homopolymers, or made with additional monomers to provide copolymers. These polymers/copolymers are then converted into photoresist compositions for use as such.

  • Publication number: 20100204362
    Abstract: The invention provides compositions of matter, methods of their synthesis, and methods of their use in polymerization reactions. The compositions include polyfunctional initiators used to make star polymers when polymerized with monomers. The polyfunctional initiators are synthesized out of a multifunctional core with at least two functional groups and two or more initiator units bonded to the functional groups. The initiator units have two electron-withdrawing groups bonded to a central carbon atom and an azo group between the central carbon atom and the functional group. The polyfunctional initiators are particularly effective because when they decompose to form the radical core of a star polymer, the electron-withdrawing groups prevent the corresponding radical from forming any linear polymer contamination and only desired star polymers result.

  • Patent number: RE44032
    Abstract: Disclosed is a new ionic liquid monomer salt and methods of is synthesis and polymerization. The ionic liquid monomer salt is prepared by mixing equimolar amounts of an amine, such as tris[2-(2-methoxyethoxy)-ethyl]amine and an acid functionalized polymerizable monomer, such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), which is stirred at ambient temperature until salt formation is complete. Also disclosed is a new ionic liquid polymer salts and method for making the same. The synthesis of AMPS 2-acrylamido-2-methyl-1-propanesulfonic acid-ammonium salt polymer is accomplished by adding 2,2?-azobisisobutyronitrile (AIBN) to the ionic liquid monomer salt and heating the homogeneous melt at 70° C. for 18 hr.
