摘要： The storage stability of otherwise unstable premix compositions for flame retardant rigid polyurethane foams containing in the premix a chlorinated polyether polyol and a tertiary amine catalyst, is enhanced by incorporation into the premix of a minor amount of a vinyl monomer. The preferred vinyl monomers employed are condensation products of acrylic or methacrylic acid with alcohols or amines. Such stabilization prevents premature deactivation of the tertiary amine catalysts contained in the premix.
摘要翻译：在预混合氯化聚醚多元醇和叔胺催化剂中含有的阻燃硬质聚氨酯泡沫塑料的其它不稳定的预混物组合物的储存稳定性通过掺入少量乙烯基单体的预混物而增强。所用的优选的乙烯基单体是丙烯酸或甲基丙烯酸与醇或胺的缩合产物。这种稳定化防止预混物中所含的叔胺催化剂的过早失活。

摘要： Prepolymers which contain isocyanate groups, have an NCO content of at least 30.0% by weight and can be prepared by reacting an isocyanate mixture consisting predominantly of diphenylmethane diisocyanates and polyphenylpolymethylene polyisocyanates and having a proportion of two-ring isomers of not more than 74% by weight with at least 4-functional polyols or a mixture of polyols having a mean functionality of at least 4, where the polyols or polyol mixtures have a hydroxyl number of from 200 to 1650 mg KOH/g and a number average molecular weight of less than 1100 g/mol. The present invention also provides a process for preparing these prepolymers containing isocyanate groups, provides for their use for producing polyurethanes and provides a process for producing polyurethanes by reacting at least one novel prepolymer containing isocyanate groups, if desired in admixture with further organic and/or modified organic isocyanates (a), with compounds having at least two reactive hydrogen atoms (b) in the presence of, if desired, blowing agents (c), catalysts (d) and, if desired, further auxiliaries and/or additives (e).

摘要： A composition comprises polyurethane, a two-component flame retardant system consisting of an additive first flame retardant containing organophosphorus, and a second flame retardant containing organochlorine or organobromine.The composition of the invention may be employed for polyurethane foams, especially rigid foams.Diminished combustibility for rigid foam is measured by a flame-spread index less than 75 and a smoke developed index less than 450 when subjected to ASTM Test E-84, Surface Burning Characteristics of Building Materials.Dimethyl methylphosphonate is a representative additive organophosphorus first flame retardant. Trichloroisopropyl alcohol is a representative second flame retardant containing organochlorine.

摘要： An oxyalkylated product useful for making polyurethane foams is prepared by reacting an alkylene oxide with a heated mixture of a phenol and a non-phenolic active hydrogen compound, at least one of which can be halogenated, in the presence of a catalyst complex of a phenol and an iron or aluminum substance. The mixture can also include a neutral phosphorus compound and/or acid anhydrides to enhance flame retardant properties. Optionally, also, the oxyalkylation reaction can be terminated by adding a tri (lower alkyl) amine and alkylene oxide to react with residual phenolic hydrogen in the mixture.
