The kinetics of nitroxide-mediated dispersion copolymerization with crosslinking styrene (STY) and divinylbenzene (DVB) in supercritical carbon dioxide (scCO2) is addressed experimentally. 2,2,6,6-Tetramethylpiperidinyl-1-oxy (TEMPO) dibenzoyl peroxide (BPO) were used as nitroxide controller initiator, respectively. A high-pressure cell lateral sapphire windows at 120 °C 207 bar was to carry ou...

Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at differen...
