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

3,3',4,4'-Biphenyltetracarboxylic dianhydride yog ib qho tseem ceeb hauv kev tsim cov polymers uas tiv taus kub siab, xws li polyimides thiab poly(ether ether ketone) (PEEK). Cov polymers no muaj kev siv hauv aerospace, automotive, electronics, thiab lwm yam lag luam vim lawv qhov kev ruaj khov thermal, lub zog mechanical, thiab kev tiv taus tshuaj lom neeg. Cov tshuaj no kuj siv ua tus neeg sawv cev crosslinking hauv kev tsim cov epoxy resins, txhim kho lawv cov khoom thermal thiab mechanical. Tsis tas li ntawd, nws siv rau hauv kev tsim cov khoom siv hluav taws xob, xws li cov kua siv lead ua polymers thiab semiconducting polymers, vim nws muaj peev xwm muab kev ruaj khov kub siab thiab cov khoom hluav taws xob rau cov khoom kawg. Tsis tas li ntawd, 3,3',4,4'-Biphenyltetracarboxylic dianhydride yog siv rau hauv kev tshawb fawb kev kawm thiab kev lag luam rau kev kawm txog cov tshuaj tiv thaiv organic thiab tsim cov ntaub ntawv tshiab nrog cov khoom tshwj xeeb. Nws cov qauv tshuaj lom neeg tshwj xeeb thiab reactivity ua rau nws yog ib qho khoom muaj nqis hauv kev tsim cov polymers thiab cov ntaub ntawv siab heev nrog ntau yam kev siv. Hauv kev xaus lus, 3,3',4,4'-Biphenyltetracarboxylic dianhydride yog ib qho tshuaj uas siv tau rau hauv kev tsim cov polymers ua tau zoo, cov neeg sawv cev sib txuas, cov ntaub ntawv hluav taws xob, thiab kev tshawb fawb txog kev kawm. Nws cov khoom siv tshuaj lom neeg tshwj xeeb ua rau nws yog ib qho khoom muaj nqis hauv ntau yam txheej txheem kev lag luam thiab kev tshawb fawb txog kev tshawb fawb.
