摘要：New hydroxyalkyl-1,2,4-triazolidine-3,5-diones corresponding to the generalFormula I ##STR1## in which R.sup.1 represents a monofunctional to pentafunctionalorganic radical, optionally substituted and/or optionally interrupted by hetero atoms orhetero atom groups,< P>< P>R. sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same ordifferent and represent hydrogen, an aliphatic C.sub.1 -C.sub.1 O-radical, a cycloaliphaticC.sub.4 -C.sub. 8 radical or an araliphatic C.sub.7 -C. sub. 17 -radical, said radicals areoptionally substituted by halogen, an aromatic C.sub.6 -C.sub.16 -radical or an aromaticC.sub.6 -C.sub.16 - radical substituted by halogen, C.sub.1 -C. sub.4 -alkyl or C.sub.1 -C.sub. 4 -alkoxy, a and b are the same or different and represent a number of from 1 to30, and n=a number of from 1 to 5.

The new compounds are obtained by oxalkylation reaction using 1,2,4-triazolidine-3,5-diones of Formula I as starting materials in which a and b represent the number 0.
