以锡(II)-2-乙基己酸乙酯/醇体系为模型体系，研究了L-丙交酯聚合中的链段交换机理。MALDI-TOF谱分析和蒙特卡罗模拟表明，最接近锡原子的羰基的活性至少是链上其他羰基的100倍。
The mechanism of segmental exchange in the polymerization of L-lactide catalysed by tin(II) 2-ethylhexanoate/alcohol system was studied as a model system. It was shown by analysis of MALDI-TOF spectra and modelling by Monte Carlo that the carbonyl group closest to the tin atom is at least 100 times more reactive than other carbonyl groups along the chain.
