Telomerizations of acrylamide (AAm) or acrylic acid (AAc) were carried out using 1-dodecanethiol (LsH) or 2-propanol (iPa) as a telogen and d'-azobis- (isobutyronitrile) (AIBN) as an initiator to obtain the corresponding LsH-AAm telomers (LsCONH2 series), LsH-AAc telomers (LsCOOH series), iPa-AAm telomers (iPa-CONH
2 series), or iPa-AAc telomers (iPa-COOH series). (Tables-1, 2, and 4). LsCONH
2 series were further treated with alkaline solutions to obtain the corresponding partially saponified ones (LsCONH
2-H series). (Table-3). These reactions proceeded smoothly, and the chemical structures of these telomers were determined by elementary analyses and IR spectra. (Table-6).
In the LsCONH
2 series (Ls 5.2 CONH
2Ls 26.4 CONH
2) and the LsCOOH series (Ls 7.9 COOHLs 21.9 COOH) cmcs were related with the degrees of polymerization (n) by log cmc=0.024 n-2.528, and log cmc=0.061 n-2.877, respectively. (Table-7), The Ca
2+ sequestration capacities of these samples had tendencies contrary to those of the Cu
2+ masking capacities or CaCO
3 dispersion capacities. The LsCONH
2+ series showed excellent capacities for Ca
2+ sequestration. (Table-7). The addition of Ca
2+ to the detergent solution containing Ls 16.4CONH
2 or Ls 23.3 CONH
2 23.5 H lowered the surface tension (γ), and increased the solubility of Orange OT. (Table-8).
