Achieving high elasticity of trans-1,4-polyisoprene with a combination of radiation crosslinking and thiol–ene grafting

A two-step method to modify trans -1,4-polyisoprene (TPI): first, TPI is crosslinked by γ-ray; then, the crosslinked TPI is grafted with n -dodecanethiol by thiol–ene click chemistry. The modified TPI shows high elasticity.
