“…The value of E, obtained for the homopolymer poly-F agrees reasonably well with the results obtained by the application of the method suggested by Ozawa, l4 which gave a value of E, = 163 kJ/mol for the first step of the thermal degradation process of poly-F in the same experimental conditions used in this work. 3 The data quoted in the second column of Table 11, makes clear that E, decreases with increasing mF. Moreover, Figure 3 shows the diagram of the variation of E, with the molar fraction of diad sequences of F m F F , giving a straight line that demonstrates that there is a direct influence not only of the average composition of copolymer samples, but also of the distribution of monomeric units along the copolymer chains, reflecting the importance of the microstructure in determining the response of a copolymer system when subjected to a thermodegradative process.…”
