  • Patent number: 8580898
    Abstract: The present invention relates to a copolymer polyester resin and a molded product using the same, and more specifically to a copolymer polyester resin that contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜50 mol % of a diol compound expressed as HO—(CH2)a—CO—(CH2)b—OH (where a and b are integers in the range 1˜5), and ethylene glycol or other diols so that the sum of its entire diol composition is 100 mol % based on dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product processability and prevention of PET bottle deformation during mold processing with a heat-shrinking label by complementing low temperature shrinkage, maintaining a high shrinkage rate, and reducing shrinkage stress.

  • Publication number: 20130253163
    Abstract: A family of carboxylic acid groups containing fluorene/fluorenon copolymers is disclosed as binders of silicon particles in the fabrication of negative electrodes for use with lithium ion batteries. Triethyleneoxide side chains provide improved adhesion to materials such as, graphite, silicon, silicon alloy, tin, tin alloy. These binders enable the use of silicon as an electrode material as they significantly improve the cycle-ability of silicon by preventing electrode degradation over time. In particular, these polymers, which become conductive on first charge, bind to the silicon particles of the electrode, are flexible so as to better accommodate the expansion and contraction of the electrode during charge/discharge, and being conductive promote the flow battery current.

  • Patent number: 8535805
    Abstract: Provided herein are the polymers shown below. The value n is a positive integer. R1 is an organic group, and each R2 is H or a chemisorbed group, with at least one R2 being a chemisorbed group. The polymer may be a nanostructured film. Also provided herein is a method of: converting a di-p-xylylene paracyclophane dimer to a reactive vapor of monomers; depositing the reactive vapor onto a substrate held at an angle relative to the vapor flux to form nanostructured poly(p-xylylene) film; reacting the film with an agent to form hydrogen atoms that are reactive with a precursor of a chemisorbed group, if the film does not contain the hydrogen atoms; and reacting the hydrogen atoms with the precursor. Also provided herein is a device having a nanostructured poly(p-xylylene) film on a pivotable substrate. The film has directional hydrophobic or oleophobic properties and directional adhesive properties.
