    摘要： An electrochromic device includes: a first insulating substrate; a first conducting layer disposed over the first insulating substrate; an electrochromic layer disposed over the first conducting layer, wherein the electrochromic layer comprises an electrochromic polymer having a polymer backbone comprising one or more meta-conjugated linkers (MCLs) and one or more aromatic moieties (Ars), wherein each of the one or more MCLs is partially conjugated with one of the one or more Ars at a meta position of the one or more MCLs; an electrolyte layer disposed over the electrochromic layer; a second conducting layer disposed over the electrolyte layer; and a second insulating substrate disposed over the second conducting layer. A thickness of the electrochromic layer is from 10 nm to 1500 nm resulting in transmittance of 85%-99.9% at a wavelength of 550 nm at a neutral state of the electrochromic layer.

    摘要： A conductive polymer dispersion including:
    (a) at least one oligo- or polythiophene obtained by copolymerization of at least one monomer according to Formula I and at least one monomer according to Formula II,

    wherein
    A represents a substituted or unsubstituted C 1 to C 5 alkylene bridge;
    R is selected from the group consisting of a linear or branched substituted or unsubstituted C 1 -C 18 -alkyl group, a substituted or unsubstituted C 5 -C 12 -cycloalkyl group, a substituted or unsubstituted C 6 -C 14 -aryl group, a substituted or unsubstituted C 7 -C 18 -aralkyl group and a hydroxyl group;
    s represents an integer from 0 to 8;
    Ra and Rb are independently from each other selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkaryl group and a substituted or unsubstituted aryl or heteroaryl group;

    (b) a polymeric polyanion wherein at least 75 mol% of the monomeric units of the polymeric polyanion are functionalized with a functional group selected from the group consisting of a sulfonic acid or salt thereof, a phosphonic acid or salt thereof, a phosphate ester or salt thereof, a sulfate ester or salt thereof and a carboxylic acid or salt thereof,
    characterized in that a weight ratio of the monomer according to Formula I to the monomer according to Formula II is from 75/25 to 25/75.

    摘要： An object of the present invention is to provide a hot-melt composition which has excellent workability, hot flow resistance, balance between adhesion and detachability, volatility resistance, and hot creep resistance. The present invention is a hot-melt composition comprising: as thermoplastic elastomers (1), a styrene-based thermoplastic elastomer (1a) having a weight average molecular weight of 300,000 or more, a styrene-based thermoplastic elastomer (1b) having a styrene content of no greater than 20% by mass, and an olefin-based thermoplastic elastomer (1c) including an ethylene propylene rubber and/or butyl rubber; as tackifiers (2), an aromatic petroleum resin (2a), a terpene phenol resin (2b), and an amorphous polyalphaolefin (2c); a high molecular weight paraffin oil (3a) having a weight average molecular weight of 1,000 or more; and a low molecular weight paraffin oil (3b) having a weight average molecular weight of less than 1,000.
