The telomer indicated below was obtained by solution polymerization of methyl acrylate using 1-dodecanol as a solvent and benzoyl peroxide as an initiator. _??_ This telomer (Lo) was then treated with hydroxyl amine and sodium methoxide in benzene to obtain the corresponding polycarboxy-polyhydroxamic acid (LoHX series). Treatment of the telomer (LO) with water-acetone alkaline solution to obtain the corresponding partialy saponified ones (LoH series). LoH series were further treated with hydrazine hydrate or ethylenediamine to obtain the corresponding poly-carboxy-polyhydrazide (LoH HD series) or polycarboxy-polyamide (LoH EA series), respectively. _??_ _??_ These reactions proceed smoothly, and the chemical structures of these derivatives were determined by elementary analyses and IR spectra. These telomer type surfactants were easily soluble in water and capable of micelle formation. Further, they, especially LoHX series, formed water insoluble chelate complexes with various metal ions.
