摘　　要：以氯铂酸、四甲基二乙烯基二硅氧烷为原料,合成了氯铂酸-乙烯基硅氧烷配合物;并采用红外跟踪的方法,通过观察红外光谱中SiH键的特征吸收峰的强弱变化,考察了该配合物对含氢硅油与4,4′-二烯丙氧基二苯砜(ABPS)的硅氢加成反应的催化活性;同时,用1HNMR谱图表征了产物的结构。结果表明,该配合物能催化ABPS与含氢硅油的硅氢加成反应,在该反应中其催化活性高于氯铂酸-异丙醇、氯铂酸-四氢呋喃及氯铂酸-乙烯基硅氧烷配合物。The chloroplatinic acid-vinyl siloxane composition was synthesized by a new technoly with chloroplatinic and tetramethyldivinyldisilazane as material. The platinum catalysts were among the most frequently used metallic catalysts forhydrosilylation. The reaction of chloroplatinic acid with 1,3-divinyltetramethyldisiloxane gave a catalyst of platinum complexes. The activities of the complexes in the reaction of 4,4′-diallyldiphenylsulfone with hydrosilyl-terminated PDMS oligomer were discussed, and it was found that the catalyst had high activity.
