  • Patent number: 8686057
    Abstract: Polyurethane polymers are made from a reaction mixture that contains a polyisocyanate, a hydroxylmethyl-containing fatty acid or ester, and another polyol, polyamine or aminoalcohol. The carboxylic acid or ester group on the hydroxymethyl-containing fatty acid or ester are capable of engaging in a variety of reactions with the polyisocyanate and/or amine or hydroxyl groups present in the reaction mixture. This allows for good quality, high molecular weight polymers to be produced even though the hydroxymethyl-containing fatty acid or ester tends to be a low functionality material.
    Type: Grant

    Inventors: Hanno R. Van der Wal, Camiel F. Bartelink
  • Patent number: 8436063
    Abstract: Polymer polyols and dispersions are prepared by polymerizing certain starting materials in a continuous phase. The continuous phase includes a polyol containing hydroxylmethyl groups, which is derived from a fatty acid. The dispersed phase may be, for example, a vinyl polymer, a polyurea or a polyurethane-urea.

  • Publication number: 20100179354
    Abstract: Novel 1,3-dialkyloxy-2-propanol and alkoxylates thereof may be prepared in good yield by a convenient process comprising adding epichlorohydrin to a stoichiometric excess of alcohol, wherein the ratio of alcohol:epichlorohydrin is at least about 3:1, preferably in the presence of a Group 1A metal hydroxide and a phase transfer catalyst. The result shows excellent selectivity of to the 1,3-substitution positions, and the alkyl chain may be saturated or unsaturated and may contain one or more heteroatoms. The alkoxylates may include repeating alkoxy units in the 2-position. The compositions are useful as surfactants, diluents, and the like.

  • Publication number: 20100168450
    Abstract: Novel alkylene oxide-extended alkoxylates of a branched 1,3-dialkyl-oxy-2-propanol may be prepared by a convenient process comprising adding epichlorohydrin to a stoichiometric excess of a branched alcohol, wherein the molar ratio of branched alcohol:epichlorohydrin is at least about 3:1, preferably in the presence of a Group 1 A metal hydroxide and a phase transfer catalyst, followed by alkoxylation in the presence of an ionic catalyst. The branched alkyl chain may be saturated or unsaturated and may contain one or more heteroatoms. The repeating alkoxy units from the alkylene oxide are in the 2-position. The compositions are useful as surfactants, diluents, and the like, and may be less expensive than other branched surfactants.

  • Publication number: 20040147628
    Abstract: Disclosed is a polyfunctional liquid polyurethane-containing adduct wherein the adduct contains as a first functional group at least one structo-terminal polymerizable group and at least one second structo-terminal functional group per molecule which is a fluorinated moiety. Such compounds are useful in radiation curable coatings to modify the surface energy of a substrate.

  • Patent number: 6531228
    Abstract: Disclosed is a polyurethane based composition for treating textiles to provide such treated textile with oil, water or oil and water repellency. The composition comprises a polyfunctional liquid polyurethane-containing adduct wherein the adduct contains as a first functional group at least one structo-terminal blocked isocyanate moiety per molecule, and at least one second structo-terminal functional group per molecule which is a perfluoro or siloxane moiety.

  • Patent number: 6162862
    Abstract: Disclosed is a urethane-based composition of value in surface coating applications, including treatment of glass or textiles, in adhesives and in the manufacture of a stabilized latex. The composition comprises a polyfunctional liquid urethane-containing adduct wherein said adduct contains as a first functional group at least one isocyanate moiety per molecule, and a second functional group per molecule which is not an isocyanate moiety and which is not reactive towards isocyanate functionality. The second functional group can comprise ester, nitrile, halogen, halocarbon, siloxyl, silyl, alkyne or alkene, or combinations of two or more thereof.
