Derivat von Phosphorsäureestersatz oder-addukt oder Gemischen hiervon, Verfahren zu deren Herstellung und deren Verwendung

摘要

A derivative of phosphoric acid ester salt or phosphoric acid ester adduct or mixtures thereof is obtained from a conversion product, which is polycondensated with at least one aldehyde and which is of at least one polyol phosphoric acid ester having at least one organic nitrogen base. The derivative is advantageously used as a flame resistant and/or fire-proofing finish in plastic shaped green bodies, on porous substrates or in painting or coating systems. The production of the derivative or a mixture thereof by reacting at least one polyol with phosphorous(V) oxide and by reacting the polyol phosphoric acid ester obtained thereby with at least one organic nitrogen base while forming a phosphoric acid ester salt or phosphoric acid ester adduct is characterized in that the quantity of phosphorous(V) oxide required for the esterification is suspended in a quantity of the ester or ester mixture to be produced, whereupon the quantity of polyol required for the esterification and, optionally, water is/are added at a temperature ranging from 20 to 180 DEG C. The esterification reaction is then permitted to, in essence, completely finish, after which the product is obtained and, finally, the salt or adduct obtained by reacting this product with the organic nitrogen base is polycondensated with at least one aldehyde.
