    摘要： White graft polymer dispersions in polyoxyalkylene polyether polyols are employed together with flame retardant compounds to prepare flame retardant polyurethane foams. The polymer dispersions employ less than 0.1 mole of induced unsaturation per mole of polyol mixture. Improved processes for the preparation of these polymer dispersions employ either maleate or fumarate derived polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol with a compound selected from the group consisting of maleic acid, maleic anhydride and fumaric acid and an alkylene oxide in the presence of salts and oxides of divalent metals.

    摘要： A low viscosity, stable graft polymer dispersion is prepared by polymerizing in the presence of a free radical initiator, from about 25 to about 70 weight percent based on the total weight of the dispersion, an ethylenically unsaturated monomer or mixture of monomers, in a polyol mixture comprising (1) from about 25 to about 99 weight percent of a polyol containing from 2 to 8 hydroxyl groups and having an equivalent weight from 30 to about 200, (2) from about 1 to about 75 weight percent of a macromer containing induced unsaturation, said macromer comprising the reaction product of a polyether polyol having an equivalent weight from 100 to 10,000 with a compound having both ethylenic unsaturation and a group selected from the group consisting of a hydroxyl, carboxyl, anhydride, isocyanate and epoxy or mixtures thereof. These graft polymer dispersions are useful for preparing polyurethane products.

    摘要： Disclosed is a process for preparation of final graft polyols via a continuous process. In, addition, a final graft polyol formed by the process is disclosed. The process includes the steps of reacting a plurality of ethylenically unsaturated monomers and a reaction moderator with a macromer having induced unsaturation in the presence of a carrier polyol, a free radical polymerization initiator, and a first graft polyol. The process provides for the preparation of a final graft polyol having a solids level of from 30 to 70% in a continuous process. The final graft polyol produced by the process has a lower viscosity over a range of solids levels, a reduced amount of very large irregularly shaped particles, a reduced viscosity change in response to a change in reaction temperature compared to a typical graft polyol, a reduced tendency to foul the continuous reactor, and a broader particle size distribution compared to an identical graft polyol prepared by a semi-batch process.
