| 摘 要： | 以1.0G乙二胺为核的树状大分子聚酰胺-胺为起始剂,氢氧化钾为催化剂,分别与环氧丙烷(PO)、环氧乙烷(EO)反应合成了一系列二嵌段树枝状聚醚表面活性剂(DPE)。采用端基滴定法测定了产品的羟值,并根据理论结构计算出聚醚的相对分子质量;通过吊环法测定聚醚的表面张力,并探讨了化学结构对其性能的影响。结果表明这类具有新型化学结构的聚醚具有良好的表面活性,树枝状聚醚的表面活性随PO比率的提高而增强,而当聚醚的结构(EO/PO)相同时,相对分子质量对其表面活性的影响不大。

| Abstract: | A series of two block dendritic polyether surfactants(DPE)were synthesized through addition reaction of ethylene oxide and propylene oxide to the initiator polyamido-amine(PAMAM)with 1.0G ethylenediamine as core under the help of catalyst KOH.The hydroxyl values of the polyether surfactants were measured by end group titration;and the calculation of their molecular weight were based upon their corresponding theoretical molecular structure.Surface tension of these(dendritic) polyethers were measured by ring ... |
