A series of polyureas5a‐cbearing vinylcyclopropane (VCP) moiety in their main chains was synthesized by the polyaddition of diamine2bearing VCP moiety with diisocyanates. Upon treatment of polyurea5bwith thiols in the presence of azobisisobutyronitrile (AIBN), the VCP moieties in the polymer main chain efficiently reacted with the thiols via a sequence of the radical addition of thiol to the vinyl group and the ring opening of the cyclopropane ring, yielding the corresponding networked polymers9–11. The thermogravimetric analysis of the networked polymers9–11revealed that their residual weight at 350 °C was higher than that of the precursor polyurea5b.
