Cas no: 89-32-7 PMDA Pyromellitic dianhydride
Pyromellitic dianhydride (PMDA), o oloa mama e pa'epa'e pe lanu samasama tioata. Faʻaalia i le ea susu o le a vave faʻafefete le susu mai le ea ma faʻafefeteina i le Pyromellitic Acid. Dissolved i le dimethyl sulfoxide, dimethylformamide, acetoneand isi solvents organic, e le mafai ona faʻaaogaina i le eter, chloroformand benzene. E masani ona faʻaaogaina e pei o mea mataʻutia mo polyimide, ma sui faʻafesoʻotaʻi mo le gaosiga o le epoxy curing agent andthe polyester resin extinction.
