Cationic Polymerization within Van Der Waals Clusters of the Form (CH2=R)n Where R=CH2, CF2 and CHCH3)

Abstract

The cluster ion mass spectra resulting from electron ionization of van der Waals clusters composed of ethene, 1, 1-difluoroethene or propene molecules were observed as a function of expansion and ionization conditions. Expansion conditions favoring the formation of large neutral clusters lead to the observation of anomalous ion intensity distributions characterized by strong peaking as a function of cluster size. Comparisons are made between the present results and previous observations in both the gas and condensed phases. We propose that the anomalous cluster ion distributions arise as a consequence of the production of molecular (i.e., covalently bonded) ions produced by a series of intracluster addition (polymerication) reactions.
