Products Description
Polycarbonate falls into the polyester polymer category, whose molecular chain is structured by crosslinking dihydric or polyhydric phenol monomers via carbonate bonding groups. Regular general-purpose polycarbonate is synthesized from 2,2-bis(4-hydroxyphenyl)propane, commercially named Bisphenol A, possessing a stable and fixed repeating molecular structure.
This batch of polycarbonate is specially refined as certified GPC reference material with strictly calibrated molecular weight parameters for chromatographic calibration.
