    摘要： Touch screen displays and other coated articles demonstrating antiglare properties are provided. A method of forming an antiglare coating on a substrate is also provided, and may be used to prepare the coated articles. The method comprises: (a) heating the substrate to a temperature of at least 100 °F (37.8 °C) to form a heated substrate; (b) applying a curable film-forming composition on at least one surface of the heated substrate to form a substrate coated with a sol-gel layer; and (c) subjecting the coated substrate to thermal conditions for a time sufficient to effect cure of the sol-gel layer. The curable film-forming composition comprises:
    (i) a silane;
    (ii) a mineral acid; and
    (iii) a solvent;
    wherein the weight ratio of mineral acid to silane is greater than 0.008:1 and the curable film-forming composition has a solids content of less than 10 percent by weight.

    摘要： An object of the present invention is to provide a copolymer rubber having processability, strength, and homogeneity, and is suitable as a modifier for resins or the like. Another object of the present invention is to provide a crosslinked rubber composition excellent in mechanical strength, abrasion resistance, and the like. Provided is a copolymer rubber obtained by copolymerizing raw materials that includes a multifunctional vinyl aromatic copolymer (A) and a conjugated diene compound (B), wherein the multifunctional vinyl aromatic copolymer (A) includes a structure unit (a) derived from a divinyl aromatic compound; a structure unit (b) derived from a monovinyl aromatic compound; and a structure unit (d) constituting a molecular end; the multifunctional vinyl aromatic copolymer (A) includes not less than 2 mol% but less than 95 mol% of the structure unit (a); the structure unit (a) partly includes vinyl group-containing structure unit (a1); the structure unit (a) partly includes, as another part, a structure unit constituting the structure unit (d); and the number average molecular weight of the multifunctional vinyl aromatic copolymer (A) is within a range of 300 to 100,000.

    摘要： Method for preparing surface-functionalized macro porous micro-clusters is proposed comprising at least the following individual steps in given order:
    a) synthesis of dispersed cross-linked polymeric latex primary core particles starting from at least one monomer or oligomer in an emulsion polymerization under starved conditions;
    b) synthesis of a shell layer on the surface of the primary core particles to form core-shell particles starting under starved conditions from the same at least one monomer or oligomer as in step a) and in addition to that at least one additional azide monomer;
    c) swelling of the core-shell particles with a liquid comprising at least one of the monomers or oligomers as used in a) as well as a polymerization initiator but preferably no azide monomer in particular not the additional azide monomer from step b);
    d) formation of agglomerates of the particles by application of shear;
    e) polymerization of the agglomerates to form the macro porous micro-clusters;
    f) direct or indirect surface-functionalization of the agglomerates by way of Cu-(I)-catalyzed or strain promoted azide-alkyne cycloaddition with the azide introduced in step b).
