  • Publication number: 20240150516
    Abstract: The present invention provides a sulfur containing polyisocyanate polyaddition (PIPA) polyether polyol dispersion at a readily processible viscosity for use in making flexible polyurethane foams having inherent flame retardant properties that comprises a polyether polyol carrier and from 10 to 25 wt. %, based on the total weight of the dispersion, of particles of a sulfur containing polyisocyanate polyaddition (PIPA) polyether polyol having a particle size diameter (PSD), as determined by laser light scattering, of 90%, by volume, of the particles in the dispersion having a maximum PSD of from 0.2 to 4.5 am and that, further, contain two or more aromatic carbamate groups. The dispersion may further comprise water or a blowing agent, g) one or more catalysts; and f) one or more polyisocyanates in a foam forming mixture.

  • Publication number: 20230109168
    Abstract: The present invention provides cooling, substantially formaldehyde and alkylphenylethoxylate (APEO) free aqueous coating compositions of a soft acrylic or vinyl copolymer binder comprising from 1.8 to 5 wt.%, based on the total weight of monomers used to make the copolymer, of an ethylenically unsaturated acid functional group containing monomer, in copolymerized form, and, in copolymerized form, an adhesion promoting ethylenically unsaturated monomer; an aqueous encapsulated PCM (phase change material) having a crosslinked acrylic shell; a nonionic associative thickener, such as a polyurethane associative thickener; and a softener. The aqueous coating compositions have a pH ranging from 7 to 8 and a solids content as high as 70 wt.% and provide soft coatings for viscoelastic polyurethane foams.

  • Patent number: 11608421
    Abstract: Dispersions of silicate particles are formed in a polyol phase. The polyol, an alkoxysilane, water and catalyst are combined and reacted under specific temperature conditions to form the silicate particles in-situ in a liquid polyol phase. The dispersions are characterized in having excellent stability.

  • Patent number: 11124595
    Abstract: A polyol composition is made by polymerizing a mixture of ethylene oxide and propylene oxide onto a mixture of at least one diol initiator and at least one triol initiator, followed by polymerizing 100% propylene oxide or a mixture of at least 90 weight percent propylene oxide and at most 10 weight percent ethylene oxide. The resulting polyol composition has a hydroxyl equivalent weight of 200 to 400 and an average nominal functionality of 2.05 to 2.95 hydroxyl groups/molecule. 5 to 30 percent of the hydroxyl groups of the coinitiated polyether polyol are primary hydroxyl groups and polymerized ethylene oxide constitutes 40 to 63 percent of the total weight of the coinitiated polyether polyol.
