Synthesis procedure
1.Place hotplate in the hood. Weigh styrene(25 g) in a 150-250 ml beaker.Heat styrene until the desired temperature,then,add benzoyl peroxide(0.1-0.4 g)with stirring the reaction mixture and maintain the reaction temperature. The solution will change to pale yellow.
2.If there are some bubbles occur cue to boiling of monomer, take out the reaction beaker from hotplate and let it cool until bubbles disappear then heat the reaction again until solution becomes viscous.
3.Pour the mixture form the beaker into the mold and let it cool to room temperature. Clean beakers immediate using hot xylene by heating on the hotplate until the remained polymers dissolved
