The synthesis of two phenylated bifunctional monomers, dimethyl 4‐(4‐( p ‐aminophenoxy)phenyl)‐3,5,6‐triphenylphthalate and dimethyl 4‐(4‐(4‐( p ‐aminophenoxy)phenoxy)phenyl)‐3,5,6‐triphenylphthlate, was accomplished. Polymerization in solution or by a bulk polymerization procedure yielded a series of low molecular weight phenylated polyimides. The polymers were soluble in chlorinated hydrocarbons and exhibited thermal stabilities comparable to other polyimide systems.
