[0002] PHS resin, full name poly-p-hydroxystyrene, is a photoresist resin and an important component of photoresist. It is mainly used to produce photosensitive resins and other photosensitive imaging systems. PHS resin is also called polyhydroxystyrene and is a material with good development prospects in the industry. PHS manufacturing methods include anionic polymerization, RAFT active free radical polymerization, and ATRP active free radical polymerization. When producing this material, a mixing device is used to mix various raw materials.
