  • Patent number: 9018325
    Abstract: A nonmetallic compound having an ionic bond with a halide ion is used as a catalyst for living radical polymerization. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced, and it is made possible to prevent adverse effects of using a radical initiator (such as side reactions). The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor, etc. The catalyst can be applied to various monomers and enables synthesis of high molecular weight polymers.

  • Publication number: 20140256894
    Abstract: The present invention relates to solar cells and discloses a difluoro benzotriazolyl organic semiconductor material and preparation method and use thereof. The organic semiconductor material is represented by formula (I), wherein both R1 and R2 are C1 to C20 alkyl, and n is an integer from 10 to 50. In the difluoro benzotriazolyl organic semiconductor material, since the 1,2,3-benzotriazole organic semiconductor material contains two fluorine atoms, the HOMO energy level is reduced by 0.11 eV, while the fluorine-substituted 1,2,3-benzotriazole has two imido groups with electron-withdrawing ability; the fluorine-substituted 1,2,3-benzotriazole is a heterocyclic compound with strong electron-withdrawing ability, and an alkyl chain can be easily introduced to the N-position of the N—H bond of the benzotriazole. The functional group of the alkyl chain can improve the solar energy conversion efficiency, thus solving the low efficiency problem of solar cells made of the organic semiconductor material.

    Abstract: A ?-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer is generally provided, which can include a polymerizable group, a linker group, and a ?-conjugated aromatic/heteroaromatic side chain. The ?-conjugated aromatic/heteroaromatic side chain includes a first cyclopentadiene ring covalently attached to the linder group, a set of second cyclopentadiene rings covalently attached to the first cyclopentadiene ring, and a third cyclopentadiene ring positioned at a terminal end of the ?-conjugated aromatic/heteroaromatic side chain such that the set of second cyclopentadiene rings is positioned between the first cyclopentadiene ring and the third cyclopentadiene ring. Methods are also provided for forming a polymer via polymerizing the ?-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer, and for grafting a ?-conjugated aromatic/heteroaromatic oligomer-containing polymer onto a surface of a nanomaterial.

  • Patent number: 8785548
    Abstract: Styrenic (meth)acrylic oligomers that are prepared at lower temperature than conventional solid grade oligomers, or are hydrogenated, contain fewer terminal vinylic unsaturations, when compared to such conventional styrenic (meth)acrylic oligomers prepared by the customary high temperature processes. Styrenic (meth)acrylic oligomers that contain fewer terminal vinylic unsaturations demonstrate improved thermal stability and may provide improved resistance to UV weathering compared to the conventional and non-hydrogenated styrenic (meth)acrylic oligomers.

  • Publication number: 20140186445
    Abstract: A method for the production of biodegradable nanoparticles with an average particle size of less than 400 nm. In a first step, a macromonomer is prepared in a ring opening polymerization process between a hydrophilic acrylate compound (A) as an initiator and hydrophobic cyclic monomers (B), wherein the macromonomer comprises at least two repetitive units based on the cyclic monomer. In a second step, this macromonomer or a mixture of macromonomers and/or commercial biocompatible monomers is polymerized, e.g. in a starved, miniemulsion or emulsion radical polymerization in water in the presence of a surfactant to the nanoparticle without necessitating additional subsequent steps for the actual production of the nanoparticles. The correspondingly made nanoparticles and uses thereof also are disclosed.

  • Patent number: 8735496
    Abstract: The present invention relates to a process for the production of the largest possible spherical, monodisperse polyvinylpyrrolidone (PVP) seed particles in the micron range by dispersion polymerisation. The particles obtained in this way represent novel starting materials for the production of macroporous polymer particles, which can in turn be employed in preparative and analytical chromatography for protein preparation. They can also be employed as base material for further reactions. The novel process for the polymerisation of N-vinylpyrrolidone, which is inexpensive to carry out, gives particles having optimised quantities, such as monodispersity, sphericity and particle diameter, which can be employed in further reactions and have advantageous, in particular improved, properties for use in chromatographic separation methods.
