| Research Abstract |
Reaction of amino-acid-containing diamine monomers with carbon disulfide and the following polycondensation of the products with dihalide monomers afforded the corresponding polypeptide-like polymers with dithiocarbamate bonds in their main chains. Photo-irradiation to these polymers induced dynamic main-chain exchange through dithiocarbamates. Exchange reaction of imines introduced at side chains of poly(L-lysine) with low-molecular-weight aldehydes was also examined, and relatively fast imine-aldehyde exchange was observed.
