Subsequently, the carbon double bonds involved in the copolyester main chain were subjected to dihydroxylation with catalyst of osmium tetroxide (OsO4), N-methylmorpholine N-oxide (NMO) and water to prepare novel biodegradable copolyesters bearing hydrophilic hydroxyl pendant groups.
然后在催化剂四氧化锇和N-甲基吗啉-N-氧化物以及水存在下，使高分子链中的不饱和碳碳双键发生氧化双羟基化反应，制备具有亲水性侧羟基的新型功能性高分子。
