<p>Expandable polystyrene contains up to 40 wt.% recycled polystyrene. It is obtd. by dissolving the recycled material in styrene monomer and polymerising this soln. in aq. suspension, with addn. of finely-divided polyethylene wax (I) and/or a mol.wt. regulator (II) during polymerisation. Pref. the material is treated with 0.05-1.0 wt.% (I) and/or 10-5000 ppm (II). (I) has a Mn of 2000-6000. (II) is dimerised alpha -methylstyrene.</p> |
