例如,将分子量为1450、3350、6000的PEG静脉注射于兔子(最大总剂量为10g/kg)时,没有发现对动物有毒性。上个世纪60年代,美国Union Carbide公司也曾经对系列的小分子PEG(分子量200-9000Da)进行了系统的研究,发现这些小分子PEG总的来说是非常安全的,小鼠、大鼠、猪、猴子、兔子等的LD50 (g/kg 体重)都在10-50之间...
The hydrophilicity of nanofibers was modified by the addition of poly (ethylene glycol) (PEG) with molecular weight of 1500 in different weight (0, 5, 10, 15, and 20 wt% related to the PLA content) and also by the addition of PEG with different molecular weights (6000, 3350, 1500, ...
