Coarse‐Grained Simulations Rationalize Thermosensitivity and Hydrolytic Degradation of Vinyl Copolymers Obtained by Radical Ring‐Opening Polymerization

open access: yesAngewandte Chemie, EarlyView.
Coarse‐grained (CG) molecular dynamics simulations were used to predict the upper critical solution temperature of copolymers obtained by radical ring‐opening copolymerization of cyclic ketene acetals and vinyl monomers, and to account for their unique degradation kinetics under physiological conditions by evaluating the solvation of their ester groups.
