摘要
Abstract
Functionalized poly (ethylene glycol) methyl ether end capped with five-membered cyclic carbonate (mPEG-GC) was synthesized from mPEG, succinic anhydride and glycerol-I, 2-carbonate. Reaction rate constants and activation energy were determined from the model reaction between mPEG-GC and amines at different temperatures. The carbonate conversion increased with the reaction time, amine dosage and temperature, while showed a maximum upon increasing the reactant concentration. The activation energy (E~) in the reaction of mPEG GC with heptyl amine is the lowest(5. 63 kJ/mol). The reaction rate constant for mPEG-GC with cyclohexyl amine is larger than that with 2-aminoheptane at the same temperature关键词
