  • Polyamide from bis(aminomethyl)tricyclodecane
    Patent number: 4609723
    Abstract: Polyamide resins are disclosed of polymeric fat acids or certain dicarboxylic acids derived from a fatty acid and a bis(aminomethyl)tricyclodecane. Copolymerized acids or diamine or amino acids may be present. Because of the greater rigidity of some of the resins in addition to the other desirable properties of the polymeric fat acid polyamides, more application areas are opened such as the injection molded or extruded structural parts and components in addition to their utility as adhesives.

  • Fatty segmented polyester elastomers
    Patent number: 4582895
    Abstract: Fatty, segmented polyester elastomers are provided which are prepared from a mixture having a molar ratio of aromatic to fatty reactants of less than 4:1 and a molar ratio of short-chain diol to long-chain poly(ether) diol reactants of less than 49:1. These elastomers are useful as hot melt adhesives having excellent properties including resistance to embrittlement at low temperatures.

  • Urethane forming compositions based on fatty polyols
    Patent number: 4546120
    Abstract: Compositions containing an organic polyisocyanate and a fatty polyol are provided. The fatty polyols may be derived from an epoxidized fatty alcohol that has been reacted with a polyfunctional-hydroxy compound. The compositions are preferably salt-free and are useful in preparing a variety polyurethane materials.

  • Alkoxylated polyester polyols and polyurethanes made therefrom
    Patent number: 4543369
    Abstract: Alkoxylated polyester polyols useful in the manufacture of polyurethanes are disclosed. For example, 9(10)-methylhydroxymethyloctadecanoate can be reacted with bishydroxymethyltricyclodecane to prepare a polyester polyol which can be ethoxylated to prepare an alkoxylated polyester polyol. The resulting polyester polyol can be reacted with a diisocyanate, such as a modified diphenylmethane diisocyanate, to prepare a urethane elastomer.
