Overview

This work uncovers structure–reactivity relationships in copolymerization, indicating new predictive capabilities for polymer microstructures.

Key Points

  • The aim is to elucidate the complex relationships between monomer structure and copolymer reactivity using modern tools.
  • Analyzed over 450 reactivity ratios from primary literature sources.
  • Used density functional theory for parametrization of electronic and steric factors.
  • Applied data science methods to identify structure–reactivity relationships.
  • Validated findings experimentally with new monomer combinations.
  • Electronics of radical species and sterics of monomers significantly influence reactivity ratios.
  • New models predict copolymerization outcomes effectively, surpassing traditional Q-e scheme limitations.
  • Demonstrated potential for predictive modeling of comonomer sequence in polymer synthesis.
