Twenty new N,N"-polymethylenebis(N'-substituted phenyl) ureas were synthesized by the reaction of N-subsituted trichloroacetamides to various diamines.Their structures were confirmed by elemental analysis,1H NMR and IR.The preliminary biological test shows that some of the compounds have a good herbicidal activity.
