    Abstract: A system and method for anti-reflective layers is provided. In an embodiment the anti-reflective layer comprises a polymer resin which has repeating units within it. At least one of the repeating units comprises a locked unit which has a cyclic structure and a lock within the unit. After the anti-reflective layer has been applied and baked, irregularities such as voids and step heights differences that have occurred may be handled by unlocking the lock within the locked unit. This unlocking breaks the cyclic structure, allowing the polymer to take up more volume and causing the anti-reflective layer to self-expand, filling the voids and reducing the step-height. The unlocking may be performed by exposure or thermal treatments.

    Abstract: A multi-stage process for forming a liquid crystalline polymer is provided. More particularly, the process includes acetylating one or more precursor monomers and melt-polymerizing the acetylated monomers to form a prepolymer in the form of a solid particulate material. Thereafter, the prepolymer is solid-state polymerized in a fluidized bed reactor that contains a porous surface (e.g., bed, plate, grate, etc.) on which the prepolymer is supported. While supported by this porous surface, the prepolymer can become “fluidized” with a heated stream of a gas (e.g., nitrogen). In this manner, a sufficient degree of turbulence is created to distribute heat evenly around the prepolymer and cause it to rapidly reach the target reaction temperature.

    Abstract: New fluorinated ethers of aromatic acids and diesters are disclosed. These compositions can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved.

  • Patent number: 7807759
    Abstract: The present invention relates to a branched and sulphonated multi block copolymer and an electrolyte membrane using the same, more precisely, a branched and sulphonated multi block copolymer composed of the repeating unit represented by formula 1 and a preparation method thereof, a hydrogenated branched and sulphonated multi block copolymer, a branched and sulphonated multi block copolymer electrolyte membrane and a fuel cell to which the branched and sulphonated multi block copolymer electrolyte membrane is applied. The electrolyte membrane of the present invention has high proton conductivity and excellent mechanical properties as well as chemical stability, so it can be effectively used for the production of thin film without the decrease of membrane properties according to the increase of sulfonic acid group since it enables the regulation of the distribution, the location and the number of sulfonic acid group in polymer backbone.

  • Publication number: 20100167992
    Abstract: The present invention relates to polymers modified to increase their resorbability. In particular, the polymers of the invention have phenyl ester side chains which are good leaving groups and which thereby increase the resorption rate of the polymer relative to the same polymer, for example, bearing a comparable amount of an alkyl ester side chain. Such polymers are generally water insoluble, but when modified are able to solublize drugs and upon degradation and resorption, release those in a physiological environment in a controlled and/or sustained manner.

  • Publication number: 20100048855
    Abstract: Disclosed is an optical lens which can be produced by injection molding on an industrial scale and which has a high refractive index, a low Abbe's number, a low birefringence index, a high transparency and a high glass transition temperature. The optical lens can be produced by injection molding of a polycarbonate resin (preferably having a reduced viscosity of 0.2 dl/g or higher and a glass transition temperature of 120 to 160° C.), wherein the polycarbonate resin is produced by reacting a diol component comprising 99 to 51 mol % of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene and 1 to 49 mol % of bisphenol A with a carbonate diester. It becomes possible to produce an optical lens preferably having a refractive index of 1.60 to 1.65, an Abbe's number of 30 or smaller, a birefringence index of 300 nm or lower and an all light transmittance of 85.0% or higher.
