(1) Synthesis of styrene by solution polymerization

▪ reaction mechanism

AIBN , toluen
styrene polystyrene

(2) synthesized polymer`s observation

▸ The mixture was colorless liquid.
▸ When beaker was slanted, I observed that the liquid was separated into two layer.
▸ When mixture was droped on water, partially mixture was changed into the milky white liquid which has viscosity. I think that was synthesized polystyrene.


(3) synthesized polystyrene`s weight

▸ theoretical weight of polystyrene

∘ 10ml × 0.9060 g/ml = 9.06 g

▸ weight of synthesized polystyrene

∘ Weight of synthesized polystyrene wasn`t measured, because mixture (polymer and solvent) wasn`t dried and solvent (methanol and toluene) wasn`t evaporated.
