ABSTRACT OF THE DISCLOSURE An aminomethane phosphonic acid aryl ester of the following formula or salts thereof: Image where R1 stands for an optionally substituted aromatic group, an optionally substituted arylene alkylene group, an optionally substituted aliphatic group, an H atom, a group of the following formula Image , an nth part of a group of the formula Image , a Image group when n = 2, an optionally substituted amino group or a CH2-OH group, n stands for an integer with a value from 1 to 100, R2 stands for an optionally substituted aromatic group, an optionally substituted heteroaromatic group, an -H-atom, a group corresponding to the following formula Image , a -?-R7- group or a CH2-OH group, R3, R4, R5, and R6. denot- ing, independently of one another, aromatic groups or substituted aromatic groups, R7 stands for an H-atom, an optionally substituted aliphatic group, an optionally substituted aromatic group, an optionally substituted hetero aromatic group an option- ally substituted amino or imino group or an optionally substituted aromatic, hetero aromatic or aliphatic group attached through oxygen or sulphur. These esters are useful as flame retardants in foams, thermoplasts and duroplasts, and as cocondensable components in oligo and polycondensates based on monomers containing hydroxyl groups.
