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

3,3',4,4'-Biphenyltetracarboxylic dianhydride bụ ihe dị mkpa n'ịmepụta polima ndị na-eguzogide okpomọkụ dị elu, dịka polyimides na poly(ether ether ketone) (PEEK). Polima ndị a nwere ọrụ na mbara igwe, ụgbọ ala, eletrọniki, na ụlọ ọrụ ndị ọzọ n'ihi nkwụsi ike okpomọkụ ha pụrụ iche, ike mekaniki, na iguzogide kemịkalụ. A na-ejikwa ngwakọta a dị ka ihe na-ejikọ ọnụ na mmepụta nke epoxy resins, na-eme ka ihe onwunwe okpomọkụ na mekaniki ha ka mma. Na mgbakwunye, a na-eji ya eme ihe na imepụta ihe eletrọniki, dị ka polima kristal mmiri mmiri na polima semiconducting, n'ihi ikike ya inye nkwụsi ike okpomọkụ dị elu na ihe onwunwe eletriki na ngwaahịa ikpeazụ. Ọzọkwa, a na-eji 3,3',4,4'-Biphenyltetracarboxylic dianhydride na nyocha agụmakwụkwọ na ụlọ ọrụ mmepụta ihe maka ịmụ mmeghachi omume organic na ịmepụta ihe ọhụrụ nwere ihe onwunwe ahaziri ahazi. Nhazi kemịkalụ pụrụ iche ya na mmeghachi omume ya na-eme ka ọ bụrụ ihe bara uru na mmepe nke polima dị elu na ihe nwere ngwa dị iche iche. Na nchịkọta, 3,3',4,4'-Biphenyltetracarboxylic dianhydride bụ ihe mejupụtara ya nke nwere ike imepụta polima ndị nwere arụmọrụ dị elu, ihe ndị na-ejikọ ọnụ, ihe eletrọniki, na nnyocha agụmakwụkwọ. Njirimara kemịkalụ pụrụ iche ya na-eme ka ọ bụrụ ihe bara uru na usoro ụlọ ọrụ na ọrụ nyocha sayensị dị iche iche.
