Several acrylate and methacrylate telomers and acrylate-vinyl alcohol cotelomers containing sulfide and hydroxyl groups were prepared, and their detergency building powers were examined. Their Ca sequestering capacity and dispersing power for MnO<SUB>2</SUB> were also determined. The corresponding properties of sodium tripolyphosphate (STPP) and disodium 3-oxapentanedioate (ODA) were determind as the standards.<BR>The telomer type oligomers showed better building performances in detergents, and these performances depended on the molecular weight, tacticity and chemical structure of the telomers. The building performances of acrylate telomers were better than those of the corresponding methacrylate telomers. The building performances of telomers which contained chelating groups as telogens were much better than those of the corresponding telomers which had no chelating groups. The building performances of syndiotactic methacrylate oligomers were inferior to the corresponding isotactic oligomers.
