    摘要: This invention relates to polybutadiene modified polymer polyols which comprise one or more base polyols, at least one preformed stabilizer, one or more ethylenically unsaturated monomers, and polybutadiene, in the presence of at least one free radical polymerization catalyst, and optionally, one or more chain transfer agents. The polybutadiene present in these polybutadiene modified polymer polyols may be carried into the polymer polyol through the preformed stabilizer, by a polybutadiene containing component that is added separately from the preformed stabilizer to the polymer polyol, or a combination thereof, with the total amount of polybutadiene ranging from 0.03 to 1.0% by weight of polybutadiene, based on 100% by weight of the polymer polyol. The present invention also relates to processes for preparing these polybutadiene modified polymer polyols, to foams prepared from these polybutadiene modified polymer polyols, and to processes for producing foams from these polybutadiene modified polymer polyols.

    摘要: A viscoelastic polyurethane foam is the reaction product of at least one natural oil derived polyol and at least one aromatic compound having an average of more than one isocyanate group. A viscoelastic polyurethane foam has an air flow of at least about 0.5 l/s, wherein the foam is formed in the substantial absence of copolymer polyol and has not (yet) been mechanically reticulated and is preferably prepared using at least one natural oil derived polyol, more preferably in an amount of at least about 20 weight percent of the polyols used. A process of preparing a viscoelastic foam, comprises steps of (A) forming a reaction mixture including at least one polyol, at least one polyisocyanate, water, at least one catalyst wherein a the polyol comprises at least one natural oil derived polyol; and (B) subjecting the reaction mixture to conditions sufficient to result in the reaction mixture to expand and cure to form a viscoelastic polyurethane foam. In another embodiment, a process comprises steps of (a) forming a natural oil derived polyol composition comprising at least one natural oil derived polyol and water; (b) admixing at least one gelling catalyst and at least one blowing catalyst with the natural oil derived polyol composition to form a catalyst polyol admixture; (c) supplying an isocyanate in an amount corresponding to an isocyanate index for a pMDI of at least about 65 and at most about 95 or, when the isocyanate is a TDI or MDI or combination thereof, at least about 80 and at most about 105; and (c) admixing the isocyanate with the catalyst polyol admixture.

    摘要: A process of forming a polyol includes the steps of providing an alkylene oxide, providing an initiator composition having an average functionality of at least four, and providing an alkaline earth metal hydroxide and an amine. The process also includes the step of reacting the initiator composition and the alkylene oxide in the presence of the alkaline earth metal hydroxide and the amine to form the polyol. This allows the polyol to have consistent chain length and be formed with increased speed and in high yield, while reducing costs and maximizing efficiency. The polyol is reacted with an isocyanate and used to form a polyurethane article.

    摘要: The subject invention provides polyurethane foam and a method of purifying polyether polyols of non-volatile impurities for use in forming the polyurethane foam. The method includes the step of providing a crude polyether polyol having a non-volatile impurity present therein. The crude polyether polyol is contacted with an adsorbent selected from at least one of activated carbon, diatomaceous earth, charcoal, attapulgite, and clay to remove the impurity and filtered to form a purified polyether polyol. The filtering of the crude polyether polyol is carried out through a filter media that is used both in a pre-filtering step prior to adding the adsorbent and the filtering step to remove the adsorbent to reduce losses of the purified polyether polyol because of its high viscosity. The purified polyether polyol is then used to form a polyurethane foam having improved stability.
