  • Select NCO-terminated, uretdione group-containing polyurethane prepolymers and lignocellulosic composite materials prepared therefrom
    Patent number: 4522975
    Abstract: Select NCO-terminated, uretdione group-containing polyurethane prepolymers are prepared by reacting a uretdione group-containing organic polyisocyanate with an isocyanate reactive hydrogen atom-containing compound, employing a select equivalent ratio of NCO to OH ranging from about 1.5/1 to about 2/1. The polyurethane prepolymers are useful in the preparation of lignocellulosic composite materials, such as particle board, and in making coatings.

  • Graft copolymers from unsaturated monomers and peroxy di-ester polyols and polyurethanes prepared therefrom
    Patent number: 4210727
    Abstract: Graft copolymers are prepared by the polymerization of an ethylenically unsaturated monomer, or a mixture of such monomers, in the presence of a peroxy di-ester polyol. Presence of the peroxy group in the polyol reactant itself serves as a free radical initiator site for the graft copolymerization reaction. The copolymers formed are utilized in the formulation of polyurethane compositions.

  • Peroxy di-ester polyols
    Patent number: 4165432
    Abstract: Compounds containing peroxy linkages connecting similar polyol ester constituents are described. These peroxy di-ester polyols are prepared by the direct esterification of peroxy diacids with polyols, in the presence of a strong mineral acid catalyst. The peroxy di-ester polyol products function as free radical initiators and grafting bases in the graft copolymerization of unsaturated monomers with polyols. These graft copolymers are useful in the formulation of polyurethanes.
