Abstract: Process for the preparation of a stable polymer polyol having a narrow polymer particle size distribution comprising the steps of: (a) preparing a polymer seed dispersion wherein the liquid polyol medium comprises at least 30% by weight of a coupled polyol; (b) admixing a base polyol and one or more ethylenically unsaturated monomers, at least 80% by weight of which is styrene, with at least part of the polymer seed dispersion obtained in step (a) at a temperature below the polymerization temperature; and subsequently (c) heating the resulting mixture to a temperature at which polymerization occurs and allowing the polymerization to proceed until completion, thus yielding the polymer polyol. Polymer polyol comprising a liquid polyol phase and from 10 to 55% by weight based on total weight of polymer polyol of solid polymer particles stably dispersed therein, wherein the polymer particles consist essentially of polystyrene and have a mean particle size in the range of from 0.5 to 2.5 micron with a particle size span of at most 1.3. The above polymer polyols are very useful in the production of polyurethane articles, particularly polyurethane foams.

Abstract: Polyether polyol having an aromaticity in the range of from 2% to 35%, an average nominal functionality (Fn) in the range of from 2.0 to 4.5 and a hydroxyl value in the range of from 390 to 650 mg KOH/g, whereby the aromatic carbon atoms are contained in structural moieties of the general formula wherein both R1 groups independently represent hydrogen or a C1-C3 alkyl group; both R2 groups independently represent a C1-C3 alkyl group; and n is an integer of from 0 to 3. Process for the preparation of the above polyether polyol, which process comprises reacting an alkylene oxide with a polyhydric alcohol blend comprising a diphenylol alkane precursor of the above indicated structural moiety and at least one aliphatic or alicyclic polyhydric alcohol having a functionality of at least 2.0. Polyether polyol blend having an aromaticity in the range of from 2 to 10% and a Fn in the range of from 2.5 to 5.0 eq/mole, which blend comprises the above polyether polyol and one or more aliphatic or alicyclic polyether polyols having a Fn of at least 2.5. Rigid polyurethane foam having a total aromaticity in the range of from 35% to 50%, obtainable by foaming a composition comprising the above polyol or polyol blend having an aromaticity from 2 to 10% and a Fn from 2.5 to 5.0 eq/mole, and an aromatic polyisocyanate in such amount that the isocyanate index is from 100 to 150, whereby the polyol reactant accounts for from 1 and 10% of the total aromaticity of the rigid polyurethane foam.

Abstract: PURPOSE: To provide a vessel easy for operation and replace of catalyst and suitable for hydrotreatment of hydrocarbon oils by setting a bed of solid material upon a support layer fixed horizontally in the vessel and closing the support layer by a breakplate during normal operation. CONSTITUTION: A reactor comprises an inlet 2 and an outlet 9, a layer 3 distributing an inflow liquid into a catalyst bed 8, and a pipe 4 supported by the layer 3, and a new catalyst is filled through this pipe 4. Further, the reactor 1 comprises a support layer 7 having an opening 5 closed by a breakplate 6 during operation. During the operation, the catalyst bed 8 is located upon the support layer 7 and this support layer 7 distributes gases and liquids. The reactor 1 is used in the hydrotreatment, and the like, of hydrocarbons, in which, during normal operation, the opening 5 in the support layer 7 is closed completely by the breakplate 6.
