Random chain scission initiation combination termination

3 Random chain scission initiation combination termination [Pg.20]

The degradation behaviour in this case cannot be obtained from the preceding equations, which are restricted to first-order termination or second-order disproportionation termination. Another method [2] restricted to a most probable type initial distribution has shown that in this case, in the absence of transfer [Pg.20]

These equations simplify for limiting behaviour. In the short-zip case (1/7 jc0), we have [Pg.21]


Various radical chain processes have been suggested, based on initiation either at a labile centre or by random scission of a normal C—Cl bond. The Cl radical produced abstracts a methylene hydrogen and propagation then occurs along the chain or occasionally by attack on a neighbouring chain, so ending a particular polyene sequence but continuing the reaction in the other chain. Termination is assumed to be by combination of pairs of chain carriers (Scheme 23). [Pg.1240]
