Abstract

The synthesis of linear multiblock copolypeptides along with three-arm star homo- and copolypeptides was investigated. The precursors along with the final copolypeptides were characterized by membrane osmometry and size exclusion chromatography (SEC) featuring a two-angle laser scattering (TALLS) detector. In both methods, the measurements were performed at 60°C and the solvent was a 0.1N LiBr solution in N,N'-dimethylformamide (DMF). It was concluded that the livingness of the polypeptides under high-vacuum (HV) conditions can be preserved indefinitely and this allows the use of coupling chemistry for the synthesis of homo- and copolypeptides with a wide variety of macromolecular architectures.
