    摘要： A photosensitive composition is disclosed particularly for making printed circuit boards. It contains: (a) a polymer binder; (b) a photoinitiator; and (c) an unsaturated photomonomer. The polymer binder is prepared from a reaction among the following reactants: (i) a styrene-maleic anhydride resin containing repeating units of styrene and anhydride groups, (ii) an unsaturated compound containing at least one hydroxy group and at least three acrylic groups, and (iii) a saturated alcohol. The styrene-maleic anhydride resin is prepared from a polymerization reaction of styrene and maleic anhydride in a molar ratio ranging from 3:1 to 1:1, and preferably has a molecular weight between 800 and 100,000.

    摘要： A new liquid composition comprising a polyanhydride, for example, the copolymer of maleic anhydride and an alpha-olefin, an olefinically unsaturated monooxirane compound such as glycidyl methacrylate, an olefinically unsaturated monoanhydride such as maleic anhydride and an olefin such as styrene. The composition is partially cured through the olefinic groups by ionizing gradiation to an intermediate homogeneous composition which is capable of being molded, particularly when in combination with a substrate such as fiber glass, and is further cured through anhydride and epoxide groups to a solid, infusible resin.

    摘要： A METHOD IS PROVIDED FOR INCREASING THE RATE OF CURING OF A LIQUID COATING AND MOLDING COMPOSITION TO FORM AN INFUSIBLE RESINOUS ARTICLE OR COATING. THE COMPOSITION COMPRISES A SOLUTION OF A POLYMERIZABLE OLEFINICALLY UNSATURATED MONOOXIRANE COMPOUND SUCH AS GLYCIDYL METHACRYLATE, A SOLID POLYANHYDRIDE HAVING AT LEAST THREE SUCCINIC ANHYDRIDE GROUPS (EXCLUDING AROMATIC ANHYDRIDES IN WHICH THE ALPHA CARBON ATOMS OF THE ANHYDRIDE GROUP ARE INCLUDED IN THE AROMATIC RING), FOR EXAMPLE, THE COPOLYMER OF A STRAIGHT CHAIN ALPHA-MONOOLEFIN AND A MALEIC ANHYDRIDE; AND CERTAIN OLEFINICALLY UNSATURATED MONOMERS FREE OF OXIRANE OXYGEN ATOMS, SUCH AS STYRENE OR ACRYLONITRILE. THE RATE OF CURING OF THIS COMPOSITION CAN BE INCREASED BY ADDING TO THE ABOVE DESCRIBED COMPOSITION A SMALL AMOUNT OF WATER ON THE ORDER OF 0.5 WEIGHT PERCENT. THE WATER IS EFFECTIVE FOR INCREASING THE RATE OF CURING FOR THE ABOVE COMPOSITION WHETHER THE COMPOSITION IS CURED THERMALLY, WITH THE USE OF A FREE RADICAL CATALYST SUCH AS AN ORGANIC PEROXIDE, FOR EXAMPLE BENZOYL PEROXIDE, WITH A SOLUBLE TERTIARY AMINE SUCH AS 3-PICOLINE, OR WITH A COMBINATION OF HEAT, ORGANIC PEROXIDES AND TERTIARY AMINES.
