Synthesis of a new class of high-molecular-weight soluble poly(amino acid)s by oxidative polymerization of polyfunctional macromolecules
Oxidative coupling of phenol-containing macromolecules, polyglutamine and polyasparagine derivatives. has been examined to produce a new class of poly(amino acid)s, Under the conditions applied, the Fe-salen-catalyzed oxidative coupling of the polymers proceeded homogeneously, yielding exclusively soluble polymers of high molecular weight, avoiding the formation of insoluble gels.
