摘要： Polyisocyanurate polymers are prepared by polymerization of polyisocyanates in organic solvents employing trimerization catalysts. The polyisocyanates are reacted with monofunctional active hydrogen compounds prior to polymerization or subsequent to the polymerization. These polymers may be dispersed in polyols for the preparation of cellular and non-cellular polyurethane products having improved physical properties.

摘要： Low-viscous, stable polymer dispersions are prepared by blending a hydroxy-containing finely divided solid polymer with a polyol having an equivalent weight between 500 and 10,000. The resulting dispersions are particularly useful in the preparation of polyurethanes having enhanced physical properties particularly load bearing or hardness, tensile strength and tear resistance.

摘要： Graft copolymer dispersions of low viscosity and improved particle size distribution are prepared by mixing a free radical catalyst and a vinyl monomer in a static mixer and thereafter adding the catalyst-monomer mix to a polyol. The dispersions are low viscous liquids which may be advantageously employed in the preparation of polyurethanes.

摘要： Finely-divided dispersed solids are prepared by polymerizing in the presence of a free radical catalyst and an organic solvent a major amount of an ethylenically unsaturated monomer or mixture of monomers and a minor amount of a hydroxy-terminated organic compound having from one to eight hydroxyl groups, an equivalent weight of from 500 to 10,000 and containing a polymerizable carbon-to-carbon double bond. The resulting polymeric solids are particularly useful in the preparation of reinforced polymer compositions.

摘要： 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. Processes for the preparation of these polymer dispersions employ 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. The polymer dispersions are prepared in the presence of a reaction moderator and employ 50 weight percent or more of acrylonitrile.
