    摘要： Rigid polyurethane foams are produced by reacting a polyisocyanate with a polyester containing at least two isocyanate-reactive hydrogen atoms and having a molecular weight of 400 to 10,000 in the presence of water, an organic blowing agent, a flameproofing agent and a compound containing at least two isocyanate-reactive hydrogen atoms and having a molecular weight in the range from 32 to 399 as crosslinking agent, optionally in the presence of known auxiliaries and additives. The polyester, the flameproofing agent and the crosslinking agent are used in quantities such that from about 15 to about 35 parts by weight of polyester, from about 50 to about 80 parts by weight flameproofing agent and from about 5 to about 15 parts by weight of crosslinking agent (with the sum of the parts by weight of these components adding up to 100) are present. These foams are useful as insulating materials in applications where flame resistance is important.

    摘要： Improved diecuttable polyester urethane foams are provided by the inclusion in the foam formulation of specified minor amounts of certain low molecular weight polyols, typically having hydroxyl numbers of 100 or greater. Representative useful species of such polyols include aliphatic alcohols, such as glycerol and erythritol, polymethylols such as trimethylolpropane, alkanolamines such as triethanolamine and relatively low molecular weight alkylene oxide adducts such as propylene-glycerol adducts and the like. Especially effective diecuttable foam formulations are provided by further employing, as co-additives, certain alkylene oxide adducts of linear alcohols or phenols, sulfonated petroleum oils, ammonium salts and silicone-containing copolymers. If desired, the viscosity and compatibility characteristics of the additive and/or additive and co-additive mixture may be modified by the incorporation of a diluent.

    摘要： Polyester-urethane polymers, prepared from the reaction of specific molar ratios of diisocyanates with specific mixtures of polyesterdiols, glycols, triols and tetraols, and having 4-10 reactive isocyanate groups are further reacted with hydroxyalkyl acrylates through the free isocyanate functionality to provide oligomers having from about 4-10 acrylates units per each mole unit of polyurethane chain. Such polymers when crosslinked under ultraviolet radiation in the presence of photosensitizers, specific reactive monofunctional acrylate solvents and multifunctional acrylate cross-linking agents cure without air inhibition to yield superior "wet look" finishes especially useful for coating metal, wood and floor tile.
