Journal ArticleDOI
On the polymerization of acetylenic derivatives. XXIV. Some structural peculiarities of poly(.ALPHA.-ethynylnaphthalene).
TL;DR: In this paper, a poly(α-ethynylnaphthalene), (α-EN), obtained by bulk polymerization of α-EN with (PPh3)2·NiBr2.
Journal ArticleDOI
Me6-TREN/TREN Mixed-Ligand Effect During SET-LRP in the Catalytically Active DMSO Revitalizes TREN into an Excellent Ligand.
Devendra S. Maurya,Ayesha Malik,Xiaojing Feng,Xiaojing Feng,Nabil Bensabeh,Gerard Lligadas,Virgil Percec +6 more
TL;DR: The catalytic activity of DMSO facilitates the much less expensive TREN to act as a very efficient ligand that is competitive with Me6-TREN and with the mixed-ligand and revitalizes TREN into an excellent ligand.
Journal ArticleDOI
Molecular Order in the Nematic Melt of a Semiflexible Polyether by Deuteron NMR
TL;DR: The conformations and orientational order of decamethylene spacer units in the nematic melt of a semi-lexible polyether, based on 1-(4-hydroxy-4′-biphenyl)-butane and 1,10-dibromodecane-d20, have been studied by deuteron NMR methods.
Journal ArticleDOI
Synthesis of high glass transition temperature copolymers based on poly(vinyl chloride) via single electron transfer—Degenerative chain transfer mediated living radical polymerization (SET‐DTLRP) of vinyl chloride in water
Jorge F. J. Coelho,Patrícia V. Mendonça,Anatoliy V. Popov,Virgil Percec,Pedro M.O.F. Gonçalves,Maria H. Gil +5 more
TL;DR: In this article, α,ω-di(iodo) poly(isobornyl acrylate) macroiniators with number average molecular weight from Mn, TriSEC = 11,456 to Mn,TriSEC = 94,361 were synthesized by single electron transfer-degenerative chain transfer mediated living radical polymerization (SET-DTLRP) of IAC initiated with IAC and catalyzed by sodium dithionite (Na2S2O4) in water at 35 °C.
Book ChapterDOI
Molecular Engineering of Liquid Crystalline Polymers
Virgil Percec,Dimitris Tomazos +1 more
TL;DR: In this paper, the molecular engineering of main chain and side chain liquid crystalline polymers is discussed, including thermodynamics of phase transitions, isomorphism of liquid crystals and rigidity of rod-like mesogens.
