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

3,3', 4,4'-Biphenyltetracarboxylic dianhydride ke motheo wa bohlokwa wa ho kopanya di-polymer tse hanelang mocheso o phahameng, tse kang polyimides le poly(ether ether ketone) (PEEK). Di-polymer tsena di na le ditshebediso diindastering tsa difofane, tsa dikoloi, tsa elektroniki le tse ding ka lebaka la botsitso ba tsona bo ikgethang ba mocheso, matla a mechini le kganyetso ya dikhemikhale. Motswako ona o boetse o sebediswa e le moemedi wa ho hokahanya tlhahiso ya di-resin tsa epoxy, ho ntlafatsa thepa ya tsona ya mocheso le ya mechini. Ho feta moo, o sebediswa tlhahisong ya thepa ya elektroniki, jwalo ka di-polymer tsa kristale ya metsi le di-polymer tse tsamaisang motlakase, ka lebaka la bokgoni ba wona ba ho fana ka botsitso ba mocheso o phahameng le thepa ya motlakase dihlahisweng tsa ho qetela. Ho feta moo, dianhydride ya 3,3', 4,4'-Biphenyltetracarboxylic e sebediswa dipatlisisong tsa thuto le tsa indasteri bakeng sa ho ithuta dikarabelo tsa tlhaho le ho ntshetsa pele thepa e ntjha e nang le thepa e ikgethang. Sebopeho sa yona se ikgethang sa dikhemikhale le reactivity di etsa hore e be karolo ya bohlokwa ntshetsopeleng ya di-polymer tse tswetseng pele le thepa e nang le ditshebediso tse fapaneng. Ka bokhutšoanyane, 3,3', 4,4'-Biphenyltetracarboxylic dianhydride ke motsoako o nang le lits'ebetso tlhahisong ea li-polymer tse sebetsang hantle, li-agent tse hokahanyang, thepa ea elektroniki le lipatlisiso tsa thuto. Litšobotsi tsa eona tse ikhethang tsa lik'hemik'hale li e etsa karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri le boitekong ba lipatlisiso tsa mahlale.
