    Abstract: A method for producing a dicyclopentadiene-modified phenolic resin. The method including reusing a fluorine-based ion-exchange resin as a catalyst in a reaction between a phenol and a dicyclopentadiene, the fluorine-based ion-exchange resin having been used as a catalyst when a phenol and a dicyclopentadiene are allowed to react with each other to produce a first dicyclopentadiene-modified phenolic resin. In the method, the fluorine-based ion-exchange resin is washed with an organic solvent. The dicyclopentadiene-modified phenolic resin obtained by the method has a stable quality, has a high purity, and is inexpensive.

  • Patent number: 9796802
    Abstract: The present invention is directed to resins made from cashew nutshell liquid and vinyl hydrocarbons and processes for manufacturing the resins. These resins exhibit lower viscosity than the phenol-based homologs. They also exhibit good compatibility with a wide range of solvents, mineral and natural oils, epoxy curing agents, liquid epoxy resins, and polymers, which make them suitable additives as non-reactive diluents for solvent-free coating formulations; tackifiers for structural adhesive, pressure sensitive and hot-melt adhesives; stabilizers for lubricants, fuel and polymer formulations; plasticizers for thermoplastic polymers and processing aid for rubber compounding and stabilizers for respective rubber artifacts. These resins are also valuable precursors for the manufacture of epoxy resins and polyols for coating, adhesive and composite omulations exhibiting ameliorated performance in water repellency, anti-corrosion, and fast hardness development during cure.

  • Patent number: 8192649
    Abstract: A method of preparing a capped poly(arylene ether) resin includes reacting a capping agent with a blend of two or more poly(arylene ether) resins having different intrinsic viscosities. Cured compositions prepared from these capped poly(arylene ether) resins exhibit improved balances of stiffness, toughness, and dielectric properties compared to compositions with two or more separately capped and isolated poly(arylene ether) resins.

  • Patent number: 8158743
    Abstract: Rosin modified phenolic resins are prepared by reacting together rosin, fatty acid, phenol and aldehyde. The fatty acid may be Monomer (derived from the fatty acid dimerization process). The reaction mixture may optionally include ?,?-olefinically unsaturated carboxylic acid(s) or anhydride(s), and polyol(s). The resin may be dissolved in a solvent to form a varnish. The resin may be used as a component of inks for lithographic or gravure printing.

  • Patent number: 8148047
    Abstract: A carboxyl resin according to the present invention is obtained by a process including following steps: epoxy groups on a resin (a) having two or more epoxy groups in one molecule is made to react with 0.3-0.85 mol of a monocarboxylic acid (b) per one epoxy-group equivalent weight to obtain a reaction product (c); the epoxy group or groups on the reaction product (c) are made to react with 0.15-0.95 mol of a polybasic acid (d) per one epoxy-group equivalent weight to obtain a reaction product (e); and the epoxy group or groups on the reaction product (e) are further made to react with 1.0-5.0 mol of a monocarboxylic acid (f) per one epoxy-group equivalent weight. The carboxyl resin thus obtained has an acid value within a range from 20 to 200 mgKOH/g and is soluble in an organic solvent.

  • Publication number: 20120067734
    Abstract: Embodiments herein provide a membrane that is a product of a phenol crosslinked with one or more compounds containing an allyl group. The phenol may be electropolymerized with the allyl-containing compounds to form the crosslinked polymer. Suitable allyl-containing compounds include allylphenol, allylalcohol, allylamine, and allylcarbamide. A membrane may have one type of allyl-containing compound, or, alternatively, two or more types of compounds. As used in an analyte sensing device, a membrane formed from a crosslinked phenol may provide improved interference exclusion, peroxide response, stability, and/or solvent resistance.
