Polymer articles capable of moisture uptake in humid environments, as well as polymer articles less susceptible to moisture uptake, have improved mechanical properties, particularly improved stress relaxation behavior and set properties, when treated in accord with the heat treatment method.

  • Patent number: 8703857
    Abstract: The roller chain comprises inner link plates, a bush, outer link plates, a connecting pin, and a roller. Each of the chain components has a zinc-iron alloy ground film formed on an iron-based base material by impact zinc plating and a first coating film formed by using a water-based rust preventive paint including zinc, nitrate, and an organic compound having a mercapto group other than a mercapto group-containing silane coupling agent. Then a second coating film is formed on the first coating film by using the top coat paint comprising a pigment, sodium silicate, and an acrylic emulsion or a polyurethane water-based composition.

    Abstract: A high-resolution sensor of magnetic field sensor system and materials for use in such a system are described. The sensor systems measure a magnetic field using inorganic and/or organic magneto-optically active materials, e.g. polymer material and have an interferometer based on Faraday rotation. The polymer material is preferably in the form of a film. The polymer material has an optical property that is sensitive to the magnetic field, eg the Faraday rotation effect. The present invention also provides a sensor head structure comprising the above polymer material. The sensor head may be designed for use with an optical fiber or with mirrors In particular the present invention provides a fiber Sagnac interferometer to measure the rotation of polarized plane of light. The present invention provides a fiber or mirror based Sagnac interferometer with passive phase bias applied to magnetic field sensing.

  • Publication number: 20140031501
    Abstract: A method of extracting (meth)acrylic acid from an aqueous reaction medium into an organic phase in contact therewith is described. The aqueous reaction medium is formed from at least one base catalyst and at least one dicarboxylic acid selected from maleic, fumaric, malic, itaconic, citraconic, mesaconic, and citramalic acid or mixtures thereof in aqueous solution and contains the base catalysed decarboxylation products of the base catalysed reaction. The method includes either the addition of at least one of the said dicarboxylic acids and/or a pre-cursor thereof to the aqueous reaction medium to enhance the solvent extraction of the (meth)acrylic acid into the organic solvent or maintaining the level of base catalyst to dicarboxylic acid and/or pre-cursor at a sub-stoichiometric level during the extraction process. The method extends to a process of producing (meth)acrylic acid, its esters and polymers and copolymers thereof.

  • Patent number: 8629218
    Abstract: The present invention is directed to curable film-forming compositions comprising a film-forming resin and a crosslinking agent. The film-forming resin contains a polymer having functional aromatic groups derived from functional aromatic acids. The present invention further provides multi-component composite coating compositions comprising a first film-forming composition applied to a substrate to form a primer or base coat, and a second film-forming composition applied on top of the primer or base coat to form a top coat, the top coat comprising the composition described above. Coating compositions prepared from the curable compositions of the present invention demonstrate superior gloss and acid etch resistance properties, making them ideally suited for automotive applications.

  • Publication number: 20130345380
    Abstract: The present invention relates to an innovative polymerization technique for (meth)acrylates and styrenes, in which the polymerization is initiated by isocyanates and special bases with imine structure and is activated/accelerated by addition of ionic liquids. With this new technique, which can be employed selectively, it is also possible to produce high molecular weight poly(meth)acrylates with in some cases narrow molecular weight distribution. The (meth)acrylate notation here denotes not only methacrylate, such as methyl methacrylate, ethyl methacrylate, etc., but also acrylate, such as methyl acrylate, ethyl acrylate, etc., for example, and also mixtures of both.
