Abstract
Abstract Compounds having the formula ##STR1## WHEREIN R 1 is the R 3 --[O--(C 2 H 4 O) z C 2 H 4 --] p group of which R 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 3 is an acyl group, and z = 0 or a whole number, R 2 is hydrogen or the ##STR2## group of which R 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.
