  • Imide type prepolymer composition comprising unsaturated bis imide, diamine, and a tertiary butyl hydroquinone polymerization inhibitor
    Patent number: 4987214
    Abstract: Imide prepolymer compositions containing an unsaturated component (A) and diamine component (B) at the (A)/(B) molar ratio of 0.9-1.5 and 0.01-5.0% by weight, based on the sum of said components (A) and (B), of at least one radical polymerization inhibitors, and preferably further 0.01-5.0% by weight, based on the sum of said components (A) and (B), of at least one compound selected from the group of carboxylic acid and carboxylic acid anhydride.The imide prepolymer compositions of the present invention which contain the above-defined components in specific proportions are tough and excellent in adhesive strength to glass cloths and metals and in heat resistance.

  • Projection screen
    Patent number: 4380368
    Abstract: A projection screen comprises a metal plate member having substantially independent short raised ridges uniformly over the surface. In a process for treating the surface of a metal plate member, a metal plate member and a rough surface contacting the surface of the metal plate member are moved along respective axes intersecting at a certain angle to form raised ridges of typically 100 microns or less in length.
