ABSTRACT:
They have the formula: ##STR1## where either R.sub.1 and R.sub.2 are identical and represent --CH.sub.2 R where R=H or a C.sub.1 to C.sub.4 alkyl group or R.sub.1 and R.sub.2 together form the --CH.sub.2 (CR.sub.4 R.sub.4).sub.n --CH.sub.2 group where n=0 or 1, R.sub.4 =H or --CH.sub.3, R.sub.3 =H or --CH.sub.2 R.sub.5 where R.sub.5 =H or a C.sub.1 to C.sub.4 alkyl group. A and A.sub.1 are either identical and represent H or A and A.sub.1 together form an ethylene, trimethylene or --CH(OCH.sub.2 R.sub.6)--CH(OCH.sub.2 R.sub.6)-- radical where R.sub.6 =H or a C.sub.1 to C.sub.4 alkyl group or, when R.sub.3 =H, a 1,2 dihydroxy-ethylene group.
They are obtained by reacting a disubstituted ethanal ##STR2## with a urea ANH--CO--NHA, followed if required by etherification with an alcohol R.sub.5 CH.sub.2 OH.
