  • Patent number: 4197225
    Abstract: This application concerns compositions comprising a mixture of air-drying dicyclopentenyl acrylate or methacrylate binder and a granular or particulate aggregate material, which may comprise a hydraulic cement, and is adapted to be formed by casting, extruding, or molding in any fashion into any desired shape and air-drying and resulting shaped article, thereby producing an integral, solid article of unitary mass and structure. The dicyclopentenyl (meth)acrylate may be used as an impregnant, polymerizable in situ, for already formed articles of porous nature, e.g., concrete, wood, pressed boards, and powdered pressed metal, such as aluminum, iron, steel, etc., to reduce the permeability at their surfaces and provides hard, continuous, hydrophobic, wear-resistant, and weather-resistant surfaces thereon.

  • Patent number: 4178425
    Abstract: This invention is concerned with autoxidizable coating compositions which contain(1) a member of the group consisting of an organic polyisocyanate, an isocyanate-modified drying oil, and a uralkyd;(2) at least one non-volatile reactive liquid monomer selected from the group consisting of dicyclopentenyloxyalkyl acrylate and dicyclopentenyloxyalkyl methacrylate; and(3) an effective amount of a polyvalent metal-containing complex or salt that catalyzes the curing of (1) and (2).Use of the non-volatile reactive liquid component enables the production of coating compositions having high application solids content and yet having suitable viscosity for efficient handling.

  • Patent number: 4148987
    Abstract: Monoethylenically unsaturated derivatives of substituted benzophenones or acetophenones which are prepared by reaction of such a benzophenone or acetophenone with a vinyl benzyl halide, such as the chloride, are polymerizable to form homopolymers or copolymers e.g. with a wide variety of conventional ethylenically unsaturated monomers, especially monoethylenically unsaturated vinyl or vinylidene monomers. The resulting polymers are sensitive to radiation, such as ultraviolet light, e.g. having a wave length of 2,000 to 5,000 angstroms, and readily cross-link or cure upon exposure to such radiation. Adhesives, binders, coatings, and impregnating compositions are made from the polymers.
