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

ʻO 3,3',4,4'-Biphenyltetracarboxylic dianhydride kahi poloka hale koʻikoʻi i ka synthesis o nā polymers kūpaʻa i ka mahana kiʻekiʻe, e like me polyimides a me poly(ether ether ketone) (PEEK). Loaʻa i kēia mau polymers nā noi ma ka aerospace, automotive, electronics, a me nā ʻoihana ʻē aʻe ma muli o ko lākou kūpaʻa wela kūikawā, ka ikaika mechanical, a me ke kūpaʻa kemika. Hoʻohana ʻia ka hui ma ke ʻano he mea crosslinking i ka hana ʻana o nā resins epoxy, e hoʻonui ana i ko lākou mau waiwai thermal a me mechanical. Eia kekahi, hoʻohana ʻia ia i ka hana ʻana i nā mea uila, e like me nā polymers kristal wai a me nā polymers semiconducting, ma muli o kona hiki ke hāʻawi i ke kūpaʻa wela kiʻekiʻe a me nā waiwai uila i nā huahana hope loa. Eia kekahi, hoʻohana ʻia ʻo 3,3',4,4'-Biphenyltetracarboxylic dianhydride i ka noiʻi hoʻonaʻauao a me ka ʻoihana no ke aʻo ʻana i nā hopena organik a me ka hoʻomohala ʻana i nā mea hou me nā waiwai i hana ʻia. ʻO kona ʻano kemika kū hoʻokahi a me ka reactivity e lilo ia i mea waiwai nui i ka hoʻomohala ʻana i nā polymers holomua a me nā mea me nā noi like ʻole. I ka hōʻuluʻulu manaʻo, ʻo 3,3',4,4'-Biphenyltetracarboxylic dianhydride kahi hui me nā noi i ka hana ʻana o nā polymers hana kiʻekiʻe, nā mea crosslinking, nā mea uila, a me ka noiʻi hoʻonaʻauao. ʻO kona mau waiwai kemika kū hoʻokahi e lilo ia i mea waiwai nui i nā kaʻina hana ʻoihana like ʻole a me nā hana noiʻi ʻepekema.
