    Isicelo

    1.I-BTDA ibalulekile monomer ye-polyomide, futhi isetshenziselwa ukukhiqizwa kwezinto ze-polyomide.
    2.Isetshenziswe ekuhlolweni kwe-poltimides.
    3.I-Btda polymer enhle egeleza mahhala i-powder elungele izinhloso ezijwayelekile. I-BTDA microfine powder emangalisa kahle isiza ukuxubana kuma-resins epoxy. I-Btda Ultrapure high-puranity, i-powder ephakeme ye-polymide synthesis ebucayi.
