Polymerization

A mixture under confinement in a glass pressure bottle at 20 deg C polymerized explosively, the polymerization probably being initiated by access of light through the clear glass container. Such alkene-sulfur dioxide co-polymerizations will not occur above a ceiling temperature, different for each alkene.
Explosive polymerization is initiated by lithium nitrate+sulfur dioxide.
