| Popis: | The polymerization of hydrocarbons was investigated by measuring the hydrogen yield during the glow discharge polymerization in a closed system. It was found that the pressure change in the glow discharge polymerization of hydrocarbons was mainly due to the production of hydrogen and to the loss of vapor phase monomer by polymerization. The opening of triple or double bonds and cyclic structures plays an important role in the polymerization of hydrocarbons; however, these are not exclusive mechanisms. The major polymerization mechanism for saturated normal hydrocarbons seems to be by the formation of free radicals due to hydrogen abstraction and the recombination of these primary radicals. The polymerization due to this mechanism also seems to occur concurrently during the polymerization of hydrocarbons with multiple bond and/or cyclic structures. Aromatic hydrocarbons polymerize with very low hydrogen production, indicating that the utilization of an aromatic double bond is the major mechanism of polymerization. |
