Difunctional cyclohexadienes with dihydrophthalimide central units and phenyl side groups to increase solubility are used as bisdienes in repetitive Diels‐Alder polyadditions with bis(4‐(1,2,4,‐triazoline‐3,5‐dione‐4‐yl)phenyl)methane as a difunctional dienophile. The polymers show good solubility in CH 2 CI 2 and CHCI 3. Non‐stoichiometric Diels‐Alder polyaddition with slight excess of the bistriazo‐linedione provides the possibility of synthesizing telechelics with highly reactive triazolinedione end groups.
