Abstract
Earlier work has shown that pure isobutene gas and pure di-isobutene vapour do not undergo reaction when mixed with gaseous boron trifluoride1. In the presence of a trace of some third component, or co-catalyst as we shall call it, these monomers undergo very rapid polymerization when mixed with boron trifluoride. Water1 and t-butyl alcohol2 act as co-catalysts in this way.
