Entropy-controlled cross-linking in linker-mediated vitrimers

Abstract

Significance The recently developed linker-mediated vitrimers based on metathesis reactions offer new possibilities of processing cross-linked polymers with high mechanical performance in industry, while the design principle remains unknown. Here we propose a theoretical framework for describing the system of linker-mediated vitrimers, in which entropy is found to play a dictating role. Our mean field theory agrees quantitatively with computer simulations, and provides guidelines for the rational design of the linker-mediated vitrimers with desired properties.
