摘要

Abstract

The branching structures in natural rubber (NR) were believed to be critical for its superior mechanical properties. However

it is challenging to unravel the branching structure-function relationship of NR due to the complexity of the system. Herein

polyisoprene-(polyisoprene-

-polylactide) (PI-PLA) as model compound containing branching structure was designed and synthesized

which can improve the modulus

strength and viscoelasticity activation energy compared to those of the pristine polyisoprene (PI). The reason is that the branching structure contributes to the entanglement between polyisoprene chains. In order to probe the effect of branching structure on noncovalently crosslinked system

the polyisoprene block of PI-PLA was epoxidized and mixed with Fe

ions to introduce coordination bonds. Compared with the linear counterpart

the branching structure obviously enhanced activation energy of coordinated polyisoprenes

remarkably improving the mechanical properies of elastomer.
