Description and Uses

4-Acetoxystyrene can be used to synthesize Poly(p-hydroxystyrene) as the main component of photoresist. The chemically amplified photoresist of the poly(p-hydroxystyrene) series is currently the mainstream photoresist product in the world, and it is one of the key technologies for processing photo-etched integrated circuits and manufacturing chips.

4-Acetoxystyrene is a stable Styrene monomer which can be readily polymerized and copolymerized to low, medium and high molecular weight polymers. Undergoes free radical polymerization, similar to styrene.
