Visible-light-induced ATRP under high-pressure: synthesis of ultra-high-molecular-weight polymers.

In this study, a high-pressure-assisted photoinduced atom transfer radical polymerization ( p ≤ 250 MPa) enabled the synthesis of ultra-high-molecular-weight polymers (UHMWPs) of up to 9 350 000 and low/moderate dispersity (1.10 < Đ < 1.46) in a co-solvent system (water/DMSO), without reaction mixture deoxygenation.
