摘要：

The syntheses and separation of monotrityl PEGs with molecular weights in the range of 400-6000 were successful using PVA as matrix. The yield of monotrityl PEG is strongly dependent on the initial mole ratio of PEG-trityl chloride. It is observed that satisfactory results can only be obtained in the range of 1:1.7 to 1:2.4 (mole number of PEG/mole number of trityl chloride). The effect of reaction conditions on monosubstitution is discussed.
