Sɛnea bisphenol A BPA ne phosgene yɛ adwuma no yɛ ade titiriw a wɔde yɛ polycarbonate. Wɔ saa adeyɛ yi mu no, carbonyl carbon atom a ɛwɔ phosgene mu no wɔ electrophilicity a emu yɛ den, na phenolic hydroxyl oxygen atom a ɛwɔ bisphenol A mu no yɛ adwuma sɛ nucleophilic mfinimfini de tow hyɛ so, na ɛyɛ ade a ɛwɔ ntam. Afei, ade a ɛwɔ ntam no hwere hydrogen chloride molecule biako na ɛkɔ so ne bisphenol A BPA molecule afoforo ne phosgene yɛ adwuma, na ɛde nkakrankakra yɛ polymerizing ma ɛyɛ polycarbonate.
