α,ω‐Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1 500 to 4 000 were prepared by polycondensation, in 1‐methyl‐2‐pyrrolidone at 105°C, of potassium maleate and 1,4‐dibromobutane, 1,6‐dibromohexane or 1,8‐dibromooctane in the presence of 2‐bromoethanol. The structure of oligomers was checked by 1 H and 13 C NMR spectroscopy. In most cases the mean functionality of oligomers is reasonably close to two.
