Compounds having the formula ##STR1## WHEREIN R.sup.1 is the R.sup.3 --[O--(C.sub.2 H.sub.4 O).sub.z C.sub.2 H.sub.4 --].sub.p group of which R.sup.3 is an alkyl group with 8 to 18 carbon atoms or an alkylaryl group whose alkyl residue has at least 8 carbon atoms, or an acyl group with at least 8 carbon atoms, p has a value of 0 or 1 but must be equal to 1 when R.sup.3 is an acyl group, and z = 0 or a whole number, R.sup.2 is hydrogen or the ##STR2## group of which R.sup.4 is an alkyl residue with 1 to 4 carbon atoms, Me is a metal or an organometallic group, x is a whole number which corresponds to the valence of the metal or the organometallic group and y is 0 or any whole number less than x. These compounds are useful as corrosion inhibitors, corrosion protecting films, thickeners, and fungicides or biocides. Methods for preparing the compounds are also disclosed.
Compound corresponding to the formula ##STR11## in which R.sup.1 is the R.sup.3 --[O--(C.sub.2 H.sub.4 O).sub.z C.sub.2 H.sub.4 --].sub.p group of which
Compound corresponding to the formula ##STR13## in which R.sup.1 is the R.sup.3 --[O-(C.sub.2 --H.sub.4 O).sub.z C.sub.2 H.sub.4 --].sub.p group of which
Compound corresponding to the formula ##STR15## in which R.sup.1 is the R.sup.3 --[O-(C.sub.2 H.sub.4 O).sub.z C.sub.2 H.sub.4 --].sub.p group of which
