Abstract
Amino terminated polyacrylic acids and polyacrylic acrylates are prepared by free radical polymerization of the acid or acrylate monomers with t-Boc-aminoethanethiol as a chain transfer control agent followed by acid removal of the t-Boc group. The acids and their acrylates are precursors to form dispersants and to modify dyes.
