“…On the basis of the electron micrographs, a cylindrical morphology was proposed for PBLG-PI-PBLG triblock copolymers containing 74.6 and 81.1 mol % PBLG. Water permeability measurements also supported the microphase-separated bulk morphology [36]. The hydraulic water permeability of membranes prepared by solvent casting of the PBLG-PI-PBLG triblock copolymers was three orders of magnitude larger than that measured across pure PBLG films.…”

Peptide-synthetic hybrid block copolymers are most easily prepared via ringopening polymerization of α-amino acid N-carboxyanhydrides using appropriately endfunctionalized synthetic polymers as the macroinitiator. This class of peptide-synthetic hybrid block copolymers has been the subject of longstanding scientific interest. First reports on the structure and properties of these hybrid block copolymers date from the 1970s. The advent of more refined analytical tools has spurred the interest in these materials and has led to an increased understanding of their structure and properties. This article presents an overview of the solid-state structure, organization and properties of the major classes of peptide-synthetic hybrid block copolymers, classified according to the chemical composition of the synthetic polymer block. For each of these classes of block copolymers, results from earlier morphological studies will be discussed and compared and complemented with more recent results. Properties and possible applications of peptide-synthetic hybrid block copolymers will also be pointed out. H.-A. Klok • S.

“…40,41 In solution, stimuli-responsive micelles as a function of pH and ionic stress were obtained. 40 Interestingly, 1,4-cis-monomer units content in the described PIpolypeptide hybrids never excided 66%, [34][35][36][37][38][39][40][41] when it is known, that even small quantity of non-1,4-cis-units can change dramatically the physical properties of PI. In this work, a facile method to synthesize pure 1,4-cispoly(isoprene) macroinitiators from NR with different aminoalcohols at the chain-end(s) is described.…”

“…37 The tensile test showed that Young's modulus decreases and the value of elongation at the breaking point increases with an increase in the content of the PI block. 38 Finally, they tested compatibility of poly(BLG-b-isoprene-b-BLG) with rabbit blood and tissue demonstrating that this material had good biocompatibility. 39 Later, Lecommandoux used the same method as in ref.…”
