Styrene Monomer
« on: May 15, 2008, 03:05:46 PM »
So someone in my lab allowed styrene monomer to harden in a flask, and now we can't get the glass stopper out. We've tried using a micropipet to add toluene to dissolve it, but it doesn't seem to be working. Any ideas?

Toluene will dissolve polystyrene, just use a lot and keep at it. Let it sit in a toluene bath overnight in a fume hood if need be.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Yea  -  let it soak in for for as long as it takes  -  even a a couple of days to let the solvent seep right into the gaps.

styrene monomer is a strong organic polymer of repeating units any phenol based material at exessive amount will readily dissolve toluene..

the last word should be organic polymer of repeating units like monomer....

No!
Styrene is a monomer.
Polystyrene is an organic polymer with repeating units.
Some polymers with phenyl groups will dissolve in toluene

You've probably gotten the stopper free by now, but you could have also heated the flask up to ~200 degC or so such that the viscosity of the polymer was more manageable.
