3,3′,4,4′-Biphenyltetracarboxylic dianhydride CAS:2420-87-3

Dianhydride ya 3,3', 4,4'-Biphenyltetracarboxylic ni ingenzi mu gukora polymer zirwanya ubushyuhe bwinshi, nka polyimides na poly (ether ether ketone) (PEEK). Izi polymer zifite akamaro mu by’ikirere, imodoka, ibikoresho by’ikoranabuhanga, n’izindi nganda bitewe n’ubushyuhe bwazo budasanzwe, imbaraga za mekanike, no kudakoresha imiti. Iyi mvange kandi ikoreshwa nk'ikintu gihuza ibyuma mu gukora resine za epoxy, yongera imiterere yazo y’ubushyuhe n’imikorere ya mekanike. Byongeye kandi, ikoreshwa mu gukora ibikoresho by’ikoranabuhanga, nka polymer za kristale y’amazi na polymer zikora ibikoresho bya semiconducting, bitewe n’ubushobozi bwayo bwo gutanga ubushyuhe bwinshi n’imiterere y’amashanyarazi ku bicuruzwa bya nyuma. Byongeye kandi, dianhydride ya 3,3', 4,4'-Biphenyltetracarboxylic ikoreshwa mu bushakashatsi bw’ubushakashatsi n’inganda mu kwiga uburyo bwo gukora ibintu bishya bifite imiterere yihariye. Imiterere yayo yihariye ya shimi n’uburyo ikora bituma iba ingenzi mu iterambere rya polymer zigezweho n’ibikoresho bifite imikorere itandukanye. Muri make, dianhydride ya 3,3', 4,4'-Biphenyltetracarboxylic ni imvange ifite akamaro mu gukora polymeri zikora neza, ibikoresho bihuza, ibikoresho by'ikoranabuhanga, n'ubushakashatsi mu by'ubushakashatsi. Imiterere yayo yihariye y'ibinyabutabire ituma igira akamaro mu bikorwa bitandukanye by'inganda n'ubushakashatsi bwa siyansi.
