Аннотация

For two kinds of insulating vapours (PMMA (C5H802) and PA6-6 (C6H11ON)), we have calculated the equilibrium composition, the electrical conductivity and the net emission of radiation, in thermal plasma conditions: pressure between .1 and .8 MPa; temperature between 2000 and 10000 K for the electrical conductivity and higher than 5000 K for the radiation. The results emphasise the role of carbon species on the electrical conductivity at low temperature and on the net emission for all the temperature range. The differences between the properties of both vapours remain weak.
