摘　　要：以八甲基环四硅氧烷(D4)作为反应单体,六甲基二硅氧烷(MM)为封端剂,N-β-氨乙基-γ-氨丙基甲基二甲氧基硅烷(DL-602)为氨基硅烷偶联剂,二甲亚砜(DMSO)为促进剂,氢氧化钾为催化剂,采用本体聚合,分别在超声辐射和非超声辐射条件下,合成氨基硅油。讨论了超声功率、超声时间、促进剂、封端剂、反应温度及反应时间对产物的粘度、流体力学半径及其分布的影响。结果表明,采用超声辐射不仅能够增大产物粘度、缩小分子量的分布,还能提高催化剂的效率。当超声功率为140 W,超声时间80 min,反应温度90℃,反应时间7 h,KOH、DMSO、MM用量分别为D4单体用量的0.04%,0.5%,0.1%时,合成的氨基硅油粘度最大。The amino-silicone oil was prepared by the bulk polymerization, with and without the ultrasound radiation respectively, by using octamethylcyclotetrasiloxane （D4） as reaction monomer, hexamethyldisiloxane （MM） as capping agent, N-/3-aminoethyl-y-aminopropylmethyldimethoxysilane （ DL-602 ） as aminosilane eoupling agent, dimethyl sulfoxide （DMSO） as promoting agent, and potassium hydroxide as catalyst. The effect of ultrasonic power, ultrasonic time, promoting agent, capping agent, reaction temperature and reaction time on the viscosity, hydrodynamic radius and its distribution of amino-silicone oil was dis- cussed. The results showed that the ultrasonic radiation can not only increase the viscosity and decrease the distribution of molecular weight, but also can increase the effieiency of catalyst. When the ultrasonie power was 140W, ultrasonic time was 80 rain, reaction time was 7 h, and the amount of KOH, DMSO, MM was 0.04% ,0.5% , 0.1% of the mass of reaction monomer,respeetively ,the viscosity of amino-silicone oil was the largest.
