'''Poliestirenoa''' [(C<sub>6</sub>H<sub>5</sub>CH-CH<sub>2</sub>)<sub>n</sub>, ''n''-ren balioa lortu den polimerizazio-mailarekin aldatzen da] [[estireno]]aren [[polimerizazio]]z lortzen den [[polimero]] termoplastikoa da.
5 ⟶ 80 lerroa:
Xafla, plaka, [[apar]] eta beste era batzuetan saltzen da. [[Jostailu]]etan, etxeko tresnetan, elektrizitate-tresnetan, [[isolamendu|isolatzaile]] gisa, ontzietan, [[altzari]]ak egiteko eta beste eginkizun askotarako erabiltzen da. Industrian garrantzi handia izan du; plastikoen industriari hasiera eman zioten [[formaldehido]]aren kondentsazio bidez lortutako polimeroak adina. 1932an jarri zen salgai.
