摘要
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees 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 H-1 and C-13 NMR spectroscopy. In most cases the mean functionality of oligomers is reasonably close to two.
