摘　　要：聚醚改性聚硅氧烷表面活性剂应用领域非常广泛,具有较高的经济价值。本研究以八甲基聚硅氧烷与1,1,3,3-四甲基二硅氧烷为原料,在酸性白土催化下进行开环聚合反应,得到双氢封端的聚二甲基硅氧烷,随后以氯铂酸为催化剂,制备聚醚接枝的聚二甲基硅氧烷,并对产品进行红外光谱、凝胶渗透色谱表征,进一步研究了反应时间,催化剂用量,反应温度对聚醚接枝的聚二甲基硅氧烷反应的影响。Polyether modified polysiloxane surfactant is widely applied with high economic value.In this paper,octamethylpolysiloxane and 1,1,3,3-tetramethyldisiloxane are used as raw materials for ring-opening polymerization under the catalysis of acid clay to obtain dihydro-terminated polydimethylsiloxane.Then chloroplatinic acid was used as a catalyst to prepare polyether-grafted polydimethylsiloxane,and the product was represented with infrared spectroscopy and gel permeation chromatography.The effects of reaction time,the amount of catalyst,and reaction temperature upon ether grafted polydimethylsiloxane reaction were further studied.
