New hydroxyalkyl-1,2,4-triazolidine-3,5-diones corresponding to the general Formula I ##STR1## in which R.sup.1 represents a monofunctional to pentafunctional organic radical, optionally substituted and/or optionally interrupted by hetero atoms or hetero atom groups, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same or different and represent hydrogen, an aliphatic C.sub.1 -C.sub.1 O-radical, a cycloaliphatic C.sub.4 -C.sub.8 radical or an araliphatic C.sub.7 -C.sub.17 -radical, said radicals are optionally substituted by halogen, an aromatic C.sub.6 -C.sub.16 -radical or an aromatic C.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 to 30, 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.
