## Abstract The polymerization of exoβ2βmethylβ7βoxabicyclo[2, 2, 1] heptane by PF 5 in ethylene dichloride solution was investigated. The reaction was followed in vacuum dilatometers fitted with platinum wire electrodes, which allowed us to measure the variations of conductivity during the polymer
a Values are for individual samples. During the test, one could observe particles of the disintegrated tablet forming a ring at the bottom of the fabricated flask (Fig. 3). It is not likely that one would use the type of dissolution vessel shown in Fig. 2 when the other two types are commercially
