Polyarylene polyethers with pendant vinyl groups and process for preparation thereof
TL;DR: In this article, a method for the synthesis of polyarylene polyether (PAPE) oligomers with pendant vinyl groups is presented, which involves the chloromethylation of APS and poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) backbones.

Intramolecular charge transfer complexes: 10. Radical copolymers of methacryloyl β-hydroxyethyl-3,5-dinitrobenzoate with N-(2-hydroxyethyl)carbazolyl acrylate and methacrylate
Journal ArticleDOI
Synthesis of poly(vinyl chloride)‐b‐poly(2‐ethylhexyl acrylate)‐b‐poly(vinyl chloride) by the competitive single‐electron‐transfer/degenerative‐chain‐transfer mediated living radical polymerization of vinyl chloride initiated from α,ω‐di(iodo)poly(2‐ethylhexyl acrylate) and catalyzed with sodium dithionite in water
TL;DR: In this paper, α,ω-di(iodo)poly(2-ethylhexyl acrylate)s with number-average molecular weights of 13,700 and 20,400 were synthesized by the single-electron-transfer/degenerative-chain-transfer mediated living radical polymerization (SET-DTLRP) of 2-ethyl hexyl acylate initiated with iodoform and catalyzed by sodium dithionite in water at 23 and 30 °C.
Biaxiality in a Cyclic Thermotropic Nematic Liquid-Crystal
TL;DR: Birefringence and textural data for a ring-shaped trimeric liquid crystal are presented in this article, where the material apparently undergoes a uniaxial-to-biaxial nematic phase transition as a function of temperature.
Journal ArticleDOI

TL;DR: Structural analyses show the incorporated dendritic helical pores allow facile transport of protons across the polymersome membranes after up to one month of storage, which could provide a valuable tool for studying active transport processes in a composite membrane.
