The sheeting has unusually high short-term heat resistance, so it will not lose its watertightness when coated with hot-laid asphalt at 240.degree. C. It has better resistance to ultraviolet light than conventional polysulfide sheeting, and good penetration and compression set resistance. The sheeting can be laminated to a reinforcing layer, if desired. A continuous waterproofing layer can be formed by laying pieces of the sheeting in overlapping relation, placing an uncured polysulfide rope between the overlapping edges of adjacent pieces of sheeting, and curing the rope, thus joining the pieces to form an integral sheet. Such waterproof layers can be incorporated into paving for bridges, roofs, and other structures.

  • Patent number: 4350780
    Abstract: This invention relates to polymer/polyols prepared from an ethylenically unsaturated monomer or a mixture of such monomers and characterized by the utilization, in the preparation thereof, of certain preformed stabilizers tailored to the monomer system employed, a method of preparing such polymer/polyols, and to the preformed stabilizers themselves. In general, the stabilizer, compatible with the polyol portion of the polymer/polyol, comprises a copolymer of an anchor portion consisting of an ethylenically unsaturated monomer or mixture of such monomers and a solvatable portion consisting of a propylene oxide polymer having a number average molecular weight of at least 800. The resulting polymer/polyols are stable, fluid, essentially free from scrap and seeds as produced and contain relatively small polymer particles. In accordance with one aspect of this invention, the polymer particles are essentially spherical in shape.
