The present application can provide a preparation method that can effectively produce a polymer having desired molecular weight characteristics and solubility in a solvent, and having a monomer composition, which is designed freely and variously according to the purpose, without unnecessary components with excellent polymerization efficiency and conversion rates, and a dispersion comprising the polymer formed by the preparation method.

Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

A ring-opened copolymer composition has a ring-opened copolymer containing structural unit derived from a norbornene compound represented by general formula (1) below and structural unit derived from a monocyclic olefin, wherein a content of a norbornene compound represented by general formula (1) is 1 ppm by weight or more and 1000 ppm by weight or less based on the ring-opened copolymer, ##STR00001## wherein R.sup.1 to R.sup.4 are each a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms, or a substituent containing a halogen atom, a silicon atom, an oxygen atom or a nitrogen atom, and R.sup.2 and R.sup.3 may be bonded to each other to form a ring, and “m” is 0 or 1.

The present invention generally relates to electrochromic compounds, the synthesis method and the uses thereof, particularly to a family of conjugated electrochromic polymers containing solubilizing side chains, where at least one side chain contains amide functional groups. The disclosed conjugated electrochromic polymers with amide-containing side chains demonstrated excellent redox switching in not only organic but also aqueous media while maintaining high photo contrast. The presence of the amide groups is also beneficial when it comes to lower the oxidation onset potential of the polymers, making them attractive candidates for electrochromic in aqueous environment.

A conductive polymer dispersion of this disclosure includes: a conductive composite containing a π-conjugated conductive polymer and a polyanion; an isocyanurate-based compound; and a dispersion medium for dispersing the conductive composite.

The present application can provide a preparation method that can effectively produce a polymer having desired molecular weight characteristics and solubility in a solvent, and having a monomer composition, which is designed freely and variously according to the purpose, without unnecessary components with excellent polymerization efficiency and conversion rates, and a dispersion comprising the polymer formed by the preparation method.

Biocompatible polymer hydrogel composite structures, methods of making the composite structures, and methods of using the composite structures as scaffolds for biological tissue growth and regeneration are provided. The methods for making the composite structures start with a porous high resolution three-dimensional hydrogel scaffold in which polymer precursors are infused and then polymerized in situ to form a water-soluble, electrically conducting polymer that is bonded to and/or entrapped within the hydrogel.
