  • Patent number: 5780558
    Abstract: A low-cost way to modulate the reactivity and acid number of polyetherester thermoset resins is disclosed. "Beginning" and "end" methods for making dicyclopentadiene (DCPD)-modified polyetherester resins are described. The "beginning" method comprises first heating a polyether, DCPD, a diol, an insertion catalyst, and a carboxylic acid derivative to produce a mixture that contains the polyether and a DCPD-diol diester adduct. Increasing the temperature causes insertion of the DCPD-diol diester into the polyether to give a DCPD polyetherester resin. The "end" method reacts a polyetherester resin made by insertion with DCPD to give a DCPD polyetherester resin. Compared with DCPD polyester resins, those of the invention give more flexible thermosets. Compared with unmodified polyetherester resins, the DCPD polyetherester resins offer formulators more control over curing, which eliminates mold distortion and shrinking or cracking of thermoset parts.

  • Patent number: 5773531
    Abstract: A modified acrylic urethane prepolymer composition and an unsaturated polyester resin composition to which the prepolymer has been added. The prepolymer composition includes an acrylic urethane prepolymer prepared by the reaction of diisocyanate, like MDI, with an hydroxyl-containing acrylate monomer, such as a pentaerythritol triacrylate, which prepolymer composition may contain a styrene monomer and an inhibitor, such as benzoquinone, to retard the reaction of the prepolymer and styrene monomer prior to the addition of the prepolymer composition into the polyester resin composition. The employment of the modified urethane prepolymer composition provides for the reduction in the amount of styrene monomer used in the unsaturated resin composition and also provides for improved chemical and physical properties of the cured, unsaturated resin composition, such as a reduction in glass roll-out when the resin composition is employed with fiberglass.

  • Patent number: 5747548
    Abstract: Apparatus and method for the production of hopper feedable thermoplastic pellets having zones or compartments which contain physically separated reactants which react only after being melt-mixed, as in a screw type extruder, reciproscrew injection machine, or similar device which heat forms pellets into a larger mass. This new class of thermoplastic molding materials relies mainly on the relatively slow reaction kinetics of contained large molecule molding materials to provide a time interval after melt-mixing of zoned pelletized reactants in an extruder barrel or injection molding machine. During this time period, the thermoplastic molding material is easily filled into injection molds. As the reaction progresses, the material becomes more viscous and such flow is difficult or impossible. The involved reactions may continue after demolding at room temperature during a post molding cure, or appliance service generated heat may cause post molding cure.

  • Patent number: 5696225
    Abstract: A process for making high-performance polyetherester resins and thermosets is disclosed. A polyether polyol reacts with a dicarboxylic acid or anhydride in the presence of an insertion catalyst to produce an acid-terminated polyetherester resin. Reaction of this resin reacts with a primary diol or a diepoxy compound gives a chain-extended polyetherester resin that can be cured with a vinyl monomer to produce a high-performance polyetherester thermoset. Properties of the thermosets rival or exceed those of more expensive high-performance iso and vinyl ester resins.

  • Patent number: 5677396
    Abstract: An improved process for making polyetherester resins is disclosed. The process comprises reacting a polyether with a diol diester in the presence of a catalyst that promotes random insertion of the diester into carbon-oxygen bonds of the polyether to produce the polyetherester resin. The process of the invention offers many advantages, including higher resin yields, reduced by-product generation, and the ability to make resins with low color and low acid numbers. The resins are useful for making polyetherester thermosets.

  • Patent number: 4921890
    Abstract: A process for improving the flame retardancy, hygroscopic, soil release and other properties of a polymer substrate is provided in which the substrate is contacted with a suitable aqueous mixture containing a water-soluble monomer and an organic halogen-containing hydrophobic carrier compound at a temperature of between about 40.degree. C. to 100.degree. C. Polymerization of the monomer is thereafter initiated by a chemical or physical initiator to form a polymer evenly disposed on the substrate. The flame retardancy, hygroscopic, soil release and other surface properties of the substrate are thereby improved. The mixture may be in the form of an emulsion wherein the hydrophobic carrier compound is emulsified by an appropriate agent. The invention also pertains to the improved substrates prepared in accordance with the present process.
