It is shown that the block copolymerization of styrene and 4-vinylpyridine mediated by the nitroxide TEMPO occurs via the pseudoliving radical mechanism during initiation by both of the adducts poly(4-vinylpyridine)-TEMPO and polystyrene-TEMPO. For both systems, the M n values of the polymers ...
The molecular weights of the synthesized copolymers and block copolymers were found to increase with increasing conversion. Various nitroxides were used to prepare poly-[styrene-co-(4-vinylpyridine)] copolymers with BPO as the initiator. We found the use of 4-Oxo-TEMPO yielded high polymerization ...

Supramolecular assemblies involving interaction of a small organic molecule, 2-hydroxy-6-Naphthoic acid (HNA), with poly(styrene)-block-poly(4-vinylpyridine) (PS-b-P4VP) diblock copolymers are utilized to obtain micellar structures in solution, nanostructured thin films on flat substrates and, ...

[60] studied the rheological behavior of a neat and 3-pentadecylphenol bound to a polystyrene-block-poly(4-vinylpyridine) to obtain the optimum rheological conditions (temperature far above Tg and below TODT, frequency and strain such that the ratio of the elastic component G′ to the viscous...
Sequential anionic polymerisation routes have been used to prepare AB diblock copolymers, where A is either polystyrene or polydimethylsiloxane, and B is poly(2-vinylpyridine-1-oxide). The latter block, which is water-soluble, was obtained from the oxidation of poly(2-vinylpyridine) using peroxyace...
III. Sorption of Fe(III) ions on new crosslinked ionic polymers based on 4‐vinylpyridine: Divinylbenzene copolymers Copolymers of 4-vinylpyridine : divinylbenzene with various degrees of crosslinking have been obtained as precursors for ionic polymers. To this end, addit... V Gutanu,C Luca,C...
