摘要： Novel polymer polyols based on halogenated aromatic monomers such as tribromostyrene give polyurethane foams with improved flame retardant properties. For example, replacing conventional SAN polymer polyols with tribromostyrene (TBS)/acrylonitrile polymer polyols allows the preparation of polyurethane foams passing British Standard 5852, Part 2, Ignition Source 5 Combustion Test and having better ASTM E-906 values without the need for solid fillers such as melamine or aluminum trihydrate, although these and other flame retardant additives may be optionally employed as well. Elimination of these fillers also provides other improvements such as superior strength and better compression set properties. The TBS dispersions may also be used in conjunction with melamine to eliminate the need for liquid fire retardant additives.

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 reparation of these polymer dispersions employ either isomerized maleate containing polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol, a polycarboxylic acid anhydride and an alkylene oxide in the presence of salts and oxides of divalent metals.

摘要： A stable copolymer dispersion is prepared by addition copolymerization of (1) an adduct of an active hydrogen compound, e.g., a polyether polyol, and an active ethylenically unsaturated isocyanate, e. g., 2-isocyanatoethyl methacrylate with (2) ethylenically unsaturated monomers(s), e.g., styrene or mixture thereof with acrylonitrile, while (1) and (2) are dispersed or dissolved in an excess of an active hydrogen polyfunctional compound. The resulting dispersion has a controlled particle size and a viscosity such that it is suitably employed in the production of polyurethane foams.

摘要： This invention relates to a novel process for producing polymer/polyols characterized by the use of specific amounts of particular monomer combinations and by maintaining a low monomer concentration throughout the reaction mixture during the process. The monomer combinations are acrylonitrile or methacrylonitrile and styrene or alpha-methyl styrene. The process produces novel polymer/polyols characterized by their convertibility to low density, water-blown polyurethane foams having reduced scorch and by the relatively small size of the polymer particles.

摘要： Curable resin compositions are prepared containing a radiation-sensitive reactive diluent and a saturated polyol. Curing is accomplished by mixing the reactive diluent and the polyol with a polyisocyanate, followed by exposure of the resultant composition to radiation to polymerize the reactive diluent and then, by thermal curing, to form the hydroxyisocyanate (urethane) linkage. The fully cured resin composition is described as interpenetrated or one in which there is no cross-linking between the reactive diluent and urethane linked co-polymer. The interpenetrated resin compositions form tough and hard coatings on various substrates.

摘要： Novel improved polymer/polyol composition made by polymerizing one or more ethylenically unsaturated monomers in situ in a blend of a polyol having a number average molecular weight of at least about 76 and a preformed polymer/polyol prepared by the in situ polymerization of one or more polymerizable ethylenically unsaturated monomers in a polyol, said preformed polymer/polyl having a viscosity of not more than 40,000 cps at 25.degree. C., to form a highly stable dispersion of small polymer particles in said polyols, wherein said preformed polymer/polyol and said improved polymer/polyol composition are more stable than the polymer/polyol having the same chemical composition as said improved polymer/polyol composition but made in the absence of said preformed polymer/polyol. The novel compositions are highly useful in the production of polyurethane products.

摘要： The present invention relates to polyester polyols made from aromatic polyacid sources such as thermoplastic polyesters. The polyols can be made by heating a thermoplastic polyester such as virgin polyethylene terephthalate, recycled polyethylene terephthalate, or mixtures thereof, with a glycol to give a digested intermediate which is then reacted with a digestible polymer, which can be obtained from various recycle waste streams. The polyester polyols comprise a glycol-digested polyacid source and a further digestible polymer. The polyester polyols provide a sustainable alternative to petrochemical or biochemical based polyester polyols.
