  • Patent number: 6992224
    Abstract: Present invention relates to a process for the manufacture of fluorinated alcohols as well as borates which are employed in the manufacture of the fluorinated alcohols. Fluorinated alcohols of the formulae HOCHRCF(CF3)CHFCF(CF3)2 and HOCHRCF(CF(CF3)2)CHFCF3, HOCHRCF(CF2CF3)CH(CF3)2 and HOCHRC(CF3)2CHFCF2CF3 are made by heating a mixture of a borate of the formula (RCH2O)3B, wherein R?H or a C1 to C7 alkyl group, with perfluoro-4-methyl-2-pentene or perfluoro-2-methyl-2-pentene and a free-radical initiator to form a mixture of borates, optionally separating the mixture of borates from any reactants, solvents, and by-products; hydrolyzing the mixture of borates to form a hydrolysis product mixture; and separating the alcohols from the hydrolysis product mixture.

  • Publication number: 20060008731
    Abstract: Monomers and polymers useful for forming photoresists. More particularly, photoresists, as well as monomers and polymers for photoresists useful in micro-lithography, specifically monomers bearing acid-labile groups of reduced optical density. The resulting photoresists exhibit improved transparency to 157 nm light. The photoresist compositions are composed of a mixture of at least one water insoluble, acid decomposable polymer which is prepared from at least one monomer having a monomeric unit structure which comprises: where Hal=F, Cl or Br and X=H or F; and which is substantially transparent to ultraviolet radiation at a wavelength of about 157 nm, and at least one photoacid generator capable of generating an acid upon exposure to sufficient activating energy at a wavelength of about 157 nm.
