含苯基聚矽氧烷 (PMPS) 與聚甲基丙烯酸甲酯 (PMMA) 順序反應,可合成
互穿網型高分子 (Interpenetrating polymer networks;IPNs). 此互穿
網高分子的結構可由紅外線光譜儀 (IR),微差掃描卡計(DSC) 及 29Si
核磁共振光譜儀(NMR)鑑定。動態分析則用 13C 交叉極化(CP) 固態核磁
共振,偵測 1H 自旋自旋緩解時間(T2).另外,並用熱重量損失分析儀
(TGA)探討PMPS-PMMA IPNs 的熱裂解動力學,結果發現 IPNs 之 5% 的裂
解溫度(T5)及碳渣剩餘量(Yc)均隨著矽含量愈高有增高的趨勢,而最大熱
裂解速率溫度(Tmax)的變化則並不明顯.聚合物的熱裂解活化能,則應用
van Krevelen,Horowitz-Metzger,Coats-Redfern,MacCallum-Tanner,
Kissinger 及 Ozawa 方法,計算熱裂解活化能,並探討矽氧烷彈性體
(PMPS-networks)及 PMMA 含量對互穿網聚合物熱裂解活化能之效應,由活
化能的變化,發現PMPS-networks 改善了IPNs 的熱氧化安定性.

The synthesis of interpenetrating polymer networks ( IPNs )
based on poly(methylphenyl siloxane) and poly(methyl
methacrylate),PMPS-PMMA IPNs,was described. IPNs were obtained
by an in-situ sequential synthesis process. The PMPS-PMMA IPNs
was characterized by infrared ( IR ),nuclear magnetic resonance
( NMR ) and differential scanning calorimeter ( DSC ). The
thermal degradation of PMPS-PMMA IPNs were studied by using
thermogravimetric analysis (TGA) in nitrogen and air
atmospheres. The deconvoluted differential thermal gravimetry
(DTG) curve of PMPS-PMMA IPNs showed clearly several peaks and
that of PMMA showed three peaks. From the resulting data
the apparent activation energies (Ea) was obtained following
the method of Ozawa. The average activation energies Ea,av of
IPNs for degradation were evaluated. The values of Ea,av show
that PMPS-network decreases the thermal stability of IPNs,
while those increase the thermo-oxidative stability.
