摘　　要：采用本体聚合法合成了聚(γ-氯代吡啶);研究了其水解稳定性和热稳定性能。结果表明:聚(γ-氯代吡啶)难溶于普通有机溶剂,可溶于水并被水解断链;其水溶液粘度随放置时间延长而降低。聚(γ-氯代吡啶)热解反应级数为1.7;热解反应的活化能为97 kJ/mol。The synthesis of poly(γ-chioropyridine) and its hydrolytic and thermal stability were studied. The results showed that the polyd'-chloropyridine) was insoluble in normal organic solvents. It was soluble in water and its chains could be broken by hydrolysis. The viscosity of solution decreased with the prolonged time. The reaction order of the thermal decomposition of poly (γ-chloropyridine) was 1. 7, and the activation energy of the thermal decomposition was 9? kJ/mol.
