通过烯丙基溴的硅氢化反应,合成了γ-溴丙基甲基二氯硅烷单体(A);将(A)与β-(乙酰氧基)乙基甲基二氯硅烷单体(B)共水解,得到含溴丙基的线型聚硅氧烷(C);(C)与二甲胺反应,制得含胺基的聚硅氧烷(D);(D)在氢氧化钠的催化下,使(B)链节发生β-消除同时引起交联而莸得多孔性的含二甲胺基的聚硅氧烷树脂(SAR)。测定了(SAR)一些物性及对金属离子的吸附性能。
Γ-bromopropylmethyldichlorosilane monomer (A) was synthesized by the hydrosilylation reaction of allyl bromide; and (A) was reacted with β- (acetoxy) ethylmethyldichlorosilane monomer B) co-hydrolyzing to obtain a linear polysiloxane (C) containing bromopropyl; (C) reacting with dimethylamine to obtain an amino group containing polysiloxane (D); (D) Under the catalysis of sodium, dimethylamino-containing polysiloxane resin (SAR) that causes β-elimination of the (B) chain while causing cross-linking and porosity. Some physical properties (SAR) and adsorption properties of metal ions were determined.
