摘　　要：以马来酸酐为联接剂,蓖麻油酸、聚乙二醇（n=10、15、20）为原料合成一系列新型的非离子表面活性剂——马来酰蓖麻油酸聚乙二醇酯（MARAPEG-n）,研究聚乙二醇不同聚合度（n）对产物物化性质的影响.结果表明：当聚乙二醇的聚合度n=10,15,20时,MARAPEG-n表面张力范围为32.84~51.93 m N/m,临界胶束浓度范围为0.029~0.096 g/L,HLB值的范围为12.84~15.14,乳化时间范围为1 063~706 s,润湿时间范围为640~865 s,浊点范围为20~71℃.A series of new nonionic surfactant, namely polyethylene glycol maleoyl ricinoleate （MARAPEG-n） ,was synthesized based on maleic acid as the linker, ricin oleic acid and polyethylene glycol （PEG, n = 10,15,20 ） as original materials. The influence of different degree polymerizations （n） of PEG on the physicochemical properties of the product＇s surface was studied. The results were shown that the optimum conditions were determined such as the range of surface tension 32. 84 ~ 51.93 mN/m, critical micelle concentration 0. 029 ~ 0. 096 g/L,HLB values 12. 84 - 15. 14 emulsification time of MARAPEG-n 706 ~ 1 063 s, wetting time 640 ~ 865 s, cloud point 20 ~ 71℃.
