the vulcanization reaction of the ipn and pdms was determined by the fourier transform infrared ( ft-ir ) . the mechanism of the vulcanization did't change, no chemical reaction between the ma and the pdms appeared 紅外光譜儀對(duì)聚硅氧烷和ipn固化前后的化學(xué)結(jié)構(gòu)的分析表明,反應(yīng)按照各自機(jī)理進(jìn)行,丙烯酸甲酯與聚硅氧烷之間沒有發(fā)生化學(xué)反應(yīng),說明反應(yīng)具備ipn形成的基本條件。
