  • Publication number: 20220315691
    Abstract: Disclosed are polymer polyol compositions that include polymer particles produced from an ethylenically unsaturated compound resulting from the reaction of an amine-reactive ethylenically unsaturated compound with an amino diphenylamine, as well as to the use of such polymer polyol compositions in the production of flexible polyurethane foams. The polyurethane foam includes the reaction product of a reaction mixture that includes a polyisocyanate component and a polyol composition that includes the polymer polyol.

  • Publication number: 20220267506
    Abstract: Disclosed are amine-containing polyethers that are the reaction product of a reaction mixture comprising: (a) a polyether of the formula A(OZOX)n where (i) A is a polyether derived from a hydroxyl-functional polyether having a hydroxyl functionality (y) of 1 to 8 and an OH number of 20 to 400 mg KOH/g, wherein the free hydroxyl functionality of A is y-m, wherein m is a number having a value of 1 to 7; (ii) Z is a divalent residue comprising an alkylene oxide moiety; (iii) X is an amine reactive moiety; and (iv) n is a number having a value of 1 to 7; and (b) an amino diphenylamine. Polyol compositions that include an amine-containing polyether polyol are also described, a polymer polyol compositions, polyurethane foams and methods of producing flexible polyurethane foams.

  • Patent number: 10106653
    Abstract: The invention provides novel methods of synthesizing new monofunctional and/or multifunctional heterocyclic monomer and prepolymer alloys via a continuous solvent-free, or alternatively in-solvent, one-step high shear reactor methodology designed to eliminate the need for post-processing purification and react monomer to predictable conversions, as well as the synthesis of related compositions. Additionally, the invention allows the dispersion of reinforcements and additives while synthesizing heterocyclic monomers and formulating heterocyclic prepolymer alloys.
