Modelling of polymerization kinetics and molar mass development in the nitroxide‐mediated polymerization ( <scp>NMP</scp> ) of styrene in supercritical carbon dioxide using the <scp>PC‐SAFT</scp> equation of state

A mathematical model for polymerization kinetics and molar mass development in the nitroxide-mediated (NMP) of vinyl monomers supercritical carbon dioxide (scCO2) has been developed. The method moments is used development. perturbed-chain statistical associating fluid theory (PC-SAFT) equation state to estimate number stable phases present at equilibrium reaction mixture, critical average chain length which polymer particles are formed, monomer concentration each phase. Pure binary PC-SAFT interaction parameters estimated from liquid–liquid (LLE) liquid–vapour (LVE) experimental data 60 129°C. effect pressure on conversion styrene (Sty) using benzoyl peroxide (BPO) 2,2,6,6-Tetramethylpiperidinyl-1-oxyl (TEMPO) 120°C 300–500 bar studied. It was observed that increasing increases rate without significantly affecting
