Abstract Four new bisdienes were prepared from 2‐bromomethyl‐1,3‐butadiene and N,N‐diethyl benzidine; bis[4‐(N‐ethyl) aminophenyl]‐p‐diisopropylbenzene, 1,4‐diamino‐2,3,5,6‐tetramethylbenzene and α,α′ bis(4‐amino‐3,5‐dimethyl phenyl)‐p‐diisopropyl benzene. Polyimides were synthesized by the Diels–Alder reaction of these bisdienes and bis(4‐maleimidylphenyl)methane and bis(3‐maleimidylphenyl) sulfone. The polymers were soluble in m ‐cresol, dimethyl sulfoxide and chlorinated hydrocarbon solvents. Moderate thermal stability was observed by thermogravimetric analysis in air and nitrogen.
