本研究係利用二苯甲酮四羧酸二酐(3,3’, 4,4’benzophenone tetracarboxylic dianhydride, BTDA)與己二胺(1,6 Diaminohexane,HDA)以及不同分子量的丙胺基聚二甲基矽氧烷(α,ωdiaminopyopol polydimethyl Siloxane,APPS)共同進行聚合、環化反應以得到聚亞醯胺與矽氧之多團聯共聚物。
首先以FT-IR、1H-NMR來分析產物的分子結構與組成; TGA及DSC來測試其熱性質Tg、Tm與熱裂解溫度;並以SEM來觀察淬斷面型態。實驗結果顯示所合成的多團聯共物具有三個Tg點分別為-120、22與125℃並在250℃處具有一Tm點,SEM觀察淬斷面,聚矽氧軟鏈段含量85 wt%時聚亞醯胺形成球狀相分離結構。此一微觀相分離性質為日後開發熱塑性彈性體之重要特性。
In this study , we use 3,3’, 4,4’benzophenone tetracarboxylic dianhydride (BTDA) , 1,6 Diaminohexane (HDA) ,α,ωdiaminopyopol polydimethyl siloxane(APPS) of different molecular weigts to undergo polycondensation and imidezation to synthesize the Polyimide and Polydimethylsiloxane multiblock copolymer.
The samples are measured by FT-IR and 1H-NMR to analyze the molecular structure and composition of the polymer. The thermal properties such as Tg、Tm and Td are analyzed with TGA and DSC. The morphology and microseparation are observed by SEM.
The analysis results of products indicate that, copolymer have three Tg each are -120、22 and 125℃, and the Tm of these copolymer are 250℃.
When these multi block copolymer contains on 85 weight percent of soft segment then it will become a ball like microseparation.
The technology of Polyimide and Polydimethylsiloxane multiblock Copolymer synthesis in this research offer reference to develop high additional value thermoplastic rubber products
