N-isopropylacrylamide, which has both hydrophilic acylamino and hydrophobic isopropyl, receives much concern in recent years due to its polymers showing favorable thermosensitivity and memory effect. It has been used extensively in drug delivery, material separation, enzyme immobilization and immunoanalysis.

N-异丙基丙烯酰胺同时具有亲水性的酰胺基和疏水性的异丙基，使其系列聚合物具有优良的温敏智能特性和记忆效应，目前已广泛应用于药物缓释、物料分离、免疫分析、酶的固定等领域。

The research results indicated that the first cross-linking between the HPAM and Cr3+ in ground condition was propitious to reduce leaking of blocking agent in oil layer, and the second crosslink action between acylamino of HPAM and organic phenolic aldehyde can form the high intensity gel and it can endure high temperature.

研究结果表明，HPAM羧基与Cr~(3+)离子在地面条件下的一次交联作用有利于减少堵剂在油层的漏失量，HPAM酰胺基与有机酚醛在地层条件下的二次交联作用，能够形成耐温高强度凝胶。

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

The demulsification mechanism of PAMAM belongs to displacing mechanism. Acylamino groups of PAMAM of integral having strong polarity can take place chemical adsorption with the materials of strong polarity in the exterior of oil drop and be participated in into the membrane, which will result in adsorbed crude surfactant and other active materials to be partially displaced and reduce the intensity of interfacial film between oil and water.

其机理是由于整代的PAMAM具有强极性的酰胺基团，能与油滴表面的强极性的物质发生化学吸咐作用，参与成膜，能把原来吸咐的天然活性剂分子和其它活性物质部分顶替，削弱油水界面膜强度。
