| Abstract: | We have studied the thermal decomposition of the bromides of some N-substituted derivatives of poly(vinyl-4-pyridine). The first step of the decomposition agrees with the elimination of an ethylenic compound. This elimination is first order and the activation energy depends on the substituent, on the charge of the polymer and on the proportion of substituent. This reaction is a Hofmann reaction. |
