IPC: C08G18/46
Filed: 1965-02-05
Abstract: Phosphorus-containing polyols which contain the residues of a :b -unsaturated dicarboxylic acids and dialkyl phosphite groupings are prepared by mixing alkoxylated phosphorous acid with alkylene glycol esters of a :b -unsaturated dicarboxylic acids. The alkoxylated phosphorous acid is obtained by direct alkoxylation of phosphorous acid its pyroformic compounds using alkylene oxide, at temperatures between 40-100 DEG  C.  Many specific examples are given. Specified a :b -unsaturated dicarboxylic acids include maleic, fumaric, aconitic, itaconic and chloromaleic acids.ALSO:A process for obtaining flame-resistant foam plastics containing urethane groups, based on organic polyisocyanates, phosphorus-containing polyhydroxyl compounds and blowing agents, in which the phosphorus-containing polyhydroxyl compounds used are polyhydroxyl compounds which contain the residues of a : b -unsaturated carboxylic acids and dialkyl phosphite groupings. The polyisocyanates used may be aliphatic or aromatic, be substituted by alkoxy, NO2 or Cl groups, be modified with subequivalent amounts of polyhydroxyl compounds, contain phosphorus, be masked with (e.g.) phenols or bisulphite or contain biuret groups or isocyanurate rings.  Blowing agents which may be used include water, azo compounds, low b.p. hydrocarbons and halogenated methanes or ethanes.  The phosphorus-containing polyhydroxy compounds are conveniently derived from alkoxylated phosphorous acid and alkylene glycol esters of a : BETA-unsaturated dicarboxylic acids (see Division C2).  Suitable a : b -unsaturated dicarboxylic acids include maleic fumaric, itaconic, aconitic and chloromaleic acids and their esters. Other optional additives include emulsifiers, foam-stabilizers, dyestuffs and flame-retardants.  Foaming is advantageously conducted in the presence of a catalyst, e.g. t-amines, organo-tin-(II) compounds, acetyl acetonates of heavy metals and molybdenum glycollate.
