Pressure-Induced Polymerization: Addition and Condensation Reactions

open access: yesMolecules, 2021
Under pressure of 1–100 GPa, unsaturated organic molecules tend to form covalent bond to each other for a negative enthalpy change, which often produces polymeric materials with extended carbon skeleton.
