  • Patent number: 9522998
    Abstract: Provided are: a resin mold material and a resin replica mold material composition for imprinting having a superior mold releasability; a resin mold and a resin replica mold resulting from containing the material composition; and a method for producing them. The resin mold material or resin replica mold material composition for imprinting contains 100 parts by weight of a mold resin or replica mold resin for imprinting and 0.1 to 10 parts by weight of a curable fluoropolymer (A). Preferably, the fluoropolymer (A) has a weight-average molecular weight of 3,000 to 20,000 and results from including as repeating units (a1) an ?-position substituted acrylate having a fluoroalkyl group having 4 to 6 carbon atoms and (a2) and 5 to 120 parts by weight of a high-softening-point monomer exhibiting a glass transition point or softening point of at least 50° C. in the homopolymer state.

  • Publication number: 20150318572
    Abstract: An object of the present invention is to provide a lithium cell exhibiting a high remaining capacity after high-temperature storage, and an electrolytic solution used for the cell. The present invention relates to an electrolytic solution containing a nonaqueous solvent; an electrolyte salt; and 0.001 to 9% by mass of a compound represented by the following formula (1), wherein R1, R2 and R3 may be the same as or different from one another, each representing a hydrogen atom, a fluorine atom, a C1-C20 alkyl group, or a C1-C20 fluorinated alkyl group, where at least one of R1, R2, and R3 is a fluorine atom or a fluorinated alkyl group.

  • Publication number: 20150236378
    Abstract: An object of the present invention is to provide a lithium cell exhibiting a high remaining capacity after high-temperature storage even if used at high voltages, and an electrolytic solution used for the cell. The present invention relates to an electrolytic solution containing a nonaqueous solvent; an electrolyte salt; and 10 vol % or more of a compound represented by the following formula (1) based on 100 vol % of the nonaqueous solvent, wherein R1, R2 and R3 may be the same as or different from one another, each representing a hydrogen atom, a fluorine atom, a C1-C20 alkyl group, or a C1-C20 fluorinated alkyl group, excluding cases where all of R1, R2, and R3 are hydrogen atoms or fluorine atoms.
