  • Process for using unsaturated polyester resin composition for treating cathode-ray tubes and cathode tubes obtained thereby
    Patent number: 4893055
    Abstract: A resin composition obtained by adding maleic anhydride to an unsaturated polyester resin composition comprising (I) an unsaturated polyester, (II) a styrene monomer, and (III) at least one polymerizable unsaturated compound, in limited amounts is low in viscosity, excellent in transparency and adhesiveness, able to prevent the generation of surface defects, and thus suitable for treating cathode-ray tubes.
    Type: Grant

    Date of Patent: January 9, 1990
    Assignee: Hitachi Chemical Co., Ltd.
    Inventors: Tadashi Fuzii, Hirohumi Izumi, Etsuji Iwami, Kazuyuki Tanaka
  • Method for manufacture of polybutadiene-modified unsaturated polyester
    Patent number: 4370446
    Abstract: A method for the manufacture of a polybutadiene-modified unsaturated polyester, comprising the steps of: (I) reacting (A) an .alpha.,.beta.-unsaturated dicarboxylic acid or anhydride with (B) at least one compound selected from the group consisting of (i) air-drying allyl compounds, (ii) animal and vegetable oils or derivatives thereof and (iii) dicyclopentadiene or derivatives thereof at a (B)/(A) molar ratio within the range of from 0.8 to 1.2, and (II) reacting the resultant reaction product with (C) at least one compound selected from the group consisting of .alpha.,.omega.-polybutadiene glycol and .alpha.,.omega.-hydrogenated polybutadiene glycol. A polybutadiene-modified unsaturated polyester comprising said polybutadiene-modified unsaturated polyester and a polymerizable monomer possessing at least one double bond.
