  • Patent number: 5585438
    Abstract: Melamine thermoset resins with low formaldehyde volatiles display a remeltable solid phase, a liquid phase, and a cured solid phase. These resins are formulated from melamine, glycerol as a cross-linker, polyvinyl acetate homopolymer, and sucrose as a formaldehyde scavenger in an aqueous solvent. Optional ingredients for controlling the resin adhesive's crosslinking and/or curing rate include ethylene glycol, a pH buffering system such as citric acid/sodium diacetate, and an amine block sulfonic acid salt. The compositions are particularly useful as resins for coatings, saturations, and bonding of synthetic fibers into fabric mats, and display thermal stability and rigidity at temperatures ranging up to 370.degree.

  • Patent number: 5552488
    Abstract: In a process for crosslinking a polymer, a .beta.-dicarbonyl functionality is present as a reactive diluent and/or as a reactive solvent and/or on a crosslinking entity. The .beta.-difunctional compound reacts with formaldehyde which is either released during the crosslinking reaction (or otherwise present) whereby less formaldehyde is released, than would otherwise be released. The formaldehyde which reacts with the .beta.-dicarbonyl compound is either incorporated into the crosslinked polymer network or released in the form of a reaction product which is not as harmful to the environment as the unreacted formaldehyde. The process enables the reduction of formaldehyde release during crosslinking to levels otherwise unobtainable. Furthermore, the process enables a reduction in the amount of organic solvent utilized.

    Abstract: This invention relates to novel hydroxy-functional polyester diluents, and more particularly, to acrylic-modified hydroxy-functional polyester reactive diluents useful for blending with a variety of thermosetting or thermoplastic film-forming polymers. More specifically, the hydroxy-functional polyester reactive diluents are essentially low molecular weight polyesters derived from triols, and a combination of unsaturated monocarboxylic acids and saturated monocarboxylic acids. These hydroxy-functional polyester diluents may be copolymerized with one or more acrylic monomers, i.e. hydroxy-functional acrylic monomers, and blended with a variety of thermosetting or thermoplastic film-forming polymers. These blends of the film-forming polymers and the hydroxy-functional polyester diluents can be crosslinked with conventional crosslinking agents such as isocyanates and used in the formulation of low VOC paint compositions particularly useful as automotive topcoats.

  • Patent number: 4971711
    Abstract: Poly (C.sub.5 -C.sub.9 lactone) modified Mannich base adducts are made by reacting a C.sub.5 -C.sub.9 lactone, an amine, an aldehyde, an N-hydroxyarylamine, and a hydrocarbyl substituted C.sub.4 -C.sub.10 monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl, succinic anhydride, which, in turn, preferably is made by reacting a polymer of a C.sub.2 to C.sub.10 monoolefin, preferably polyisobutylene, having a molecular weight of about 700 to 10,000 with a C.sub.4 to C.sub.10 monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are about 0.7 to 2.00 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting adducts are useful per se as oil soluble dispersant additives. They are also useful in fuel and lubricating oil compositions, as well as in concentrates and additive packages.

  • Patent number: 4929684
    Abstract: Sidewalls (12,13) for pneumatic tires (10) having a greater stiffness improve handling and performance of the tire. The sidewalls comprise a rubber, selected from the group consisting of natural rubber, synthetic rubber and blends thereof, and from about 20 to 80 parts of a rubber compatible additive, per 100 parts of rubber capable of imparting a tensile modulus of from about 30 to 200 MPa at 10 percent elongation. Pneumatic tires provided with such sidewalls are improved and exhibit higher cornering force coefficients. A method for improving the handling characteristics of pneumatic tires includes the step of applying sidewalls to the tire carcass during building, having a tensile modulus of from about 30 to 200 MPa at 10 percent elongation.

  • Patent number: 4920175
    Abstract: Promotors for a crosslinking reaction involved in the curing of a system comprising crosslinkable polymers are bound to polymeric microparticles having a diameter of about 0.01 to 6 microns prepared by polymerizing a mixture of ethylenically unsaturated monomers. The microparticles carrying the crosslinking reaction promotor may be incorporated to coating compositions, printing inks, sealants, adhesives and other polymeric products in place of conventional crosslinking reaction promotors.
