“…Aromatic compounds such as benzene, toluene, xylene, styrene, etc, were chosen for this purpose. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] These compounds, however, were subjected to ring-opening reactions in a discharge state and yielded plasma polymers containing alkyl chains rather than aromatic groups. This unexpected evidence in these plasma polymerizations may be the result of activation processes by the action of plasma.…”
