Na22CMe2 + COCl2 → 1/n [OC2CMe2]n + 2 NaClIn in this manner, approximately one billion kilograms of polycarbonate is produced annually. Many other diols have been tested instead of bisphenol A, e.g. 1,1-bis(4-hydroxyphenyl)cyclohexane and dihydroxybenzophenone. The cyclohexane can be used as a comonomer to suppress crystallisation tendency of the BPA-derived product. PET and PETG filaments…
