Arrhenius factor susceptibilities

CH2CHR. For a fast and efficient initiation the latter species should be at least as energetically favoured as A+, and in addition Arrhenius factors must also be favourable. Those olefins susceptible to initiation by stable salts are therefore, relatively few since only a limited number of stable carbocation salts are available. 

The magnitude of w.r determines the response of a dielectric. to study this response either w or r may be varied. A wide variation of w means, experimentally, that different apparatuses have to be used, t, however, is easily and widely varied by varying the temperature. In polymers often more than one type of relaxation mechanism is encountered. Bach has a specific average relaxation time, distribution of relaxation times and temperature susceptibility. The temperature susceptibility can often be described by an Arrhenius factor [1] so that ...
