3,3'-Diamino-4,4'-dihydroxydiphenyl sulfone is a kind of fragrant heterocyclic monomer that can be used as the monomer preparing polybenzoxazoles (PBO) speciality polymer functional materials. There are under high temperatures with outstanding mechanical and dielectric properties, except for outstanding thermostability. Also, there is outstanding fibre and film performance, widely used in the aerospace cause, the textile industry and other needs to strengthen the field of resistance to heat. | [Chemical Properties]
3,3'-Diamino-4,4'-dihydroxydiphenyl sulfone is a white to grey to brown powder to crystal with a melting point of 231 °C, slightly soluble in methanol. | [Uses]
3,3'-Diamino-4,4'-dihydroxydiphenyl sulfone is an organic reagent mainly used in chemical and experimental research. 3,3'-Diamino-4,4'-dihydroxydiphenyl sulfone and its derivatives can be used in the preparation of a permanently fixing film, an anodic photosensitive resin precursor compositions and moulding compositions containing polyimide components. In addition, 3,3'-diallyl-4,4'-dihydroxydiphenyl sulfone (DA-DHDPS) can be used to prepare fast photocrosslinkable polyethersulfone coatings[1]. | [References]
