Redox active dendronized polystyrenes equipped with peripheral triarylamines

open access: yesBeilstein Journal of Organic Chemistry, 2014
Dendronized polystyrene having peripheral bromo groups was prepared from the dendronization of unfunctionalized polystyrene with dendritic diarylcarbenium ions bearing peripheral bromo groups using the “cation pool” method.

Cationic polymerization of styrene using iron-containing ionic liquid catalysts in an aqueous dispersed medium [PDF]

open access: yesPolímeros
This work aims to study the cationic miniemulsion polymerization of styrene catalyzed by iron-containing imidazolium-based ionic liquids. The polystyrenes had very high number-average molar mass around 1300 kg mol-1 at 85 °C, molar-mass dispersity close ...

Adsorption of plant phenols by polystyrene resins

open access: yesActa Societatis Botanicorum Poloniae, 2014
Adsorption of nine plant phenols by nine polystyrene ion-exchange resins was investigated in an experimental model system. The phenols were adsorbed by Amberlite CG-120 more efficiently than any other acidically charged resins tested in this study.

Thermodynamic differences between deuterated and protonated polystyrenes using reversed phase liquid chromatography

open access: yes, 2005
Deuterated compounds are generally considered to possess very similar properties to their protonated analogues. Reversed phase liquid chromatography (RPLC) was used to measure thermodynamic interactions between deuterated and protonated n-butyl ...

Bio‐based vinylphenol family: Synthesis via decarboxylation of naturally occurring cinnamic acids and living radical polymerization for functionalized polystyrenes [PDF]

open access: yes, 2020
A series of bio‐based vinylphenols or hydroxystyrenes is prepared by simple decarboxylation of various naturally occurring cinnamic acids such as o‐, m‐, and p‐coumaric; caffeic; ferulic; and sinapinic acids, which possess hydroxy groups and other ...

Enhanced Electrochemiluminescence from 3D Nanocavity Electrode Arrays

open access: yesSensors and Actuators Reports, 2022
3D arrays comprising interconnected voids have been created using nanosphere lithography (2000≤diameter≤240 nm) followed by electrodeposition of gold. The top surface was blocked with 11-mercaptoundecanoic acid and then the templating polystyrenes were ...
