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

3,3', 4,4'-Biphenyltetracarboxylic dianhydride chinhu chakakosha pakugadzira mapolymer anodzivirira kupisa kwakanyanya, akadai sepolyimides uye poly(ether ether ketone) (PEEK). Mapolymer aya anoshandiswa mundege, mota, zvemagetsi, nedzimwe nzvimbo nekuda kwekugadzikana kwawo kwakanyanya pakupisa, simba remakanika, uye kuramba makemikari. Musanganiswa uyu unoshandiswawo semushonga unobatanidza mukugadzira epoxy resins, zvichiwedzera hunhu hwavo hwekupisa uye hwemakanika. Pamusoro pezvo, unoshandiswa mukugadzira zvinhu zvemagetsi, zvakaita semapolymer ekristalo emvura uye mapolymer esemiconducting, nekuda kwekugona kwawo kupa kugadzikana kwekupisa kwakanyanya uye hunhu hwemagetsi kuzvigadzirwa zvekupedzisira. Uyezve, 3,3', 4,4'-Biphenyltetracarboxylic dianhydride inoshandiswa mukutsvagisa kwedzidzo neindasitiri pakudzidza maitiro eorganic uye kugadzira zvinhu zvitsva zvine hunhu hwakagadzirirwa. Maumbirwo ayo akasiyana emakemikari uye reactivity zvinoita kuti ive chikamu chakakosha mukugadzirwa kwemapolymer epamusoro nezvinhu zvine mashandisirwo akasiyana-siyana. Muchidimbu, 3,3', 4,4'-Biphenyltetracarboxylic dianhydride imusanganiswa une mashandisirwo mukugadzirwa kwemapolymers anoshanda zvakanyanya, ma crosslinking agents, zvinhu zvemagetsi, uye tsvakurudzo yedzidzo. Hunhu hwayo hwemakemikari hwakasiyana hunoita kuti ive chikamu chakakosha mumabasa akasiyana-siyana emaindasitiri uye mumabasa ekutsvaga kwesainzi.
