Three brothers: PES, PSU and PPSU

My name is polyethersulfone, and I belong to the sulfone family. Unlike other members of the family, we contain aromatic ring groups. There are three brothers in our family, I am the second eldest, polyethersulfone (PES, PESU), the elder brother is polyphenylene sulfone (PPSU), and the younger brother is bisphenol A polysulfone (PSU).
