由D-葡萄糖，D-glucaro-1，4：6，3-二内酯制备的糖二酸二内酯与几种亚烷基二胺在室温下无催化剂进行开环加聚。所得的新的聚酰胺携带许多侧羟基，聚（亚烷基D-葡糖酰胺），是更无定形和亲水性比相应的尼龙没有羟基，更容易水解比后者在酸性条件下。从D-甘露醇得到的另一种糖酸双内酯D-甘露糖-1，4：6，3-二内酯的开环能力低于D-葡萄糖二酸类似物。John Wiley & Sons，Inc.
Ring-opening polyaddition of a saccharic acid dilactone prepared from D-glucose, D-glucaro-1,4 : 6,3-dilactone, with several alkylenediamines proceeded at room temperature with no catalyst. The resulting new polyamides carrying many pendant hydroxyl groups, poly(alkylene D-glucaramide)s, were more amorphous and hydrophilic than the corresponding nylons having no hydroxyl groups, and were hydrolyzed more easily than the latter in an acidic condition. The ring-opening ability of D-mannaro-1,4:6,3-dilactone, which was another saccharic acid dilactone obtained from D-mannitol, was found to be lower than that of the D-glucaric analogue. © 1993 John Wiley & Sons, Inc.
