Side-Chain-Controlled Self-Assembly of Polystyrene−Polypeptide Miktoarm Star Copolymers
We show how the self-assembly of miktoarm star copolymers can be controlled by modifying the side chains of their polypeptide arms, using A2B and A2B2 type polymer/polypeptide hybrids (macromolecular chimeras). Initially synthesized PS2PBLL and PS2PBLL2 (PS, polystyrene; PBLL, poly(ε-tert-butyloxycarbonyl-L-lysine)) miktoarms were first deprotected to PS2PLLHCl and PS2PLLHCl2 miktoarms (PLLHCl,...
متن کاملEngineering of Syndiotactic and Isotactic Polystyrene-Based Copolymers via Stereoselective Catalytic Polymerization.
This contribution presents an updated overview of the different copolymers containing stereoregular polystyrene blocks. Special emphasis is placed on syndiospecific and isospecific copolymerization of styrene with co-monomers (ethylene and α-olefins, conjugated and non-conjugated dienes, styrene derivatives, etc.). The catalytic systems involved are described and the polymerization mechanisms a...
متن کاملTowards an easy access to amphiphilic rod-coil miktoarm star copolymers.
Water-soluble stimuli-responsive AB2 miktoarm star copolymers were prepared by atom transfer radical polymerisation of styrene followed by chain-end modification, polymerisation of either gamma-benzyl-L-glutamate N-carboxyanhydride or tert-butylacrylate and a final step of hydrolysis.
متن کاملSelf-assembly of miktoarm star-like ABn block copolymers: from wet to dry brushes.
Self-assembly of miktoarm star-like ABn block copolymer in both selective solvent (A- or B-selective) and miscible homopolymer matrix (A or B homopolymer), that is, formation of micelles, was for the first time investigated by theoretical calculations based on self-consistent mean field theory. Interestingly, the calculation revealed that the size of micelles in solvent was smaller than that in...
متن کاملSynthesis of Miktoarm Branched Conjugated Copolymers by ROMPing In and Out.
Architecture represents an underutilized yet promising control element in polymer design due to the challenging synthesis of compositionally varied branched copolymers. We report the one-pot synthesis of miktoarm branched polymers by ring-opening metathesis polymerization. In this work, we graft to and from telechelic poly(3-hexylthiophene), which is end-capped by oxime click chemistry, using v...
