O le BDFA o loʻo faʻaaogaina lautele e avea o se vaega taua i le tuʻufaʻatasia o polymers ma meafaitino maualuga.O lona fausaga mole mole tulaga ese, e aofia ai mama benzene e lua o loʻo faʻapipiʻi i se ivi ivi o le fluorene, e maua ai mea faʻapitoa faʻavela ma masini i polymers e maua mai.

O le tulaga maualuga o le mafanafana o le BDFA-based polymers e mafai ai ona latou tatalia le maualuga o le vevela, ma talafeagai mo faʻaoga i le aerospace, taʻavale, ma mea tau eletise.O nei polymers o loʻo faʻaalia le teteʻe mataʻina i le vevela, UV radiation, ma vailaʻau faʻamaʻi, faʻamautinoa lo latou umi ma le tumau i siosiomaga faigata.

E le gata i lea, o polymers faʻavae BDFA o loʻo i ai ni mea faʻapipiʻi eletise sili ona lelei, ma avea ai ma filifiliga lelei mo mea eletise ma eletise.O nei polymers e mafai ona faʻaaogaina i le gaosiga o insulators, mea faʻaeletoroni, ma laupapa faʻasalalau lolomi, lea e manaʻomia ai le faʻaitiitia o le eletise eletise.

O le BDFA e lauiloa foi mo lona gafatia e faʻaleleia ai le malosi faʻainisinia ma le faʻamalosi o polymers.E ala i le tuʻufaʻatasia o le BDFA i polymer matrices, o mea e maua mai e faʻaalia ai le faʻaleleia atili o le malosi, teteʻe o aʻafiaga, ma le mautu.O le mea lea e talafeagai ai mo talosaga i fale faufale, ta'avale, ma oloa fa'atau oloa.

I le faaopoopo atu i ana talosaga i polymers maualuga, e maua e le BDFA le aoga i le gaosiga o vailaʻau faʻapitoa, vali, ma pigments.O lona fausaga mole mole tulaga ese e maua ai avanoa mo aganuʻu, faʻatagaina tagata suʻesuʻe ma tagata gaosi oloa e atiaʻe mea fou ma mea faʻapitoa.
