摘要

本文研究了双功能引发剂N,N′-双[(4-t-丁基偶氮-4-氰戊基)存在下的甲基丙烯酸甲酯聚合动力学，用气相色谱法测定了热分解第一步的活化能(Ed = 74.5 kJ/mol)。通过膨胀研究，得到了与引发剂有关的反应顺序，以及聚合的总活化能(E = 78.5 kJ/mol)。

Kinetics of methyl methacrylate polymerization initiated with n,n′‐bis[(4‐t‐butylazo‐4‐cyanovaleryl)‐oxyethyl]‐azo‐bis‐formamide

This paper deals with a kinetic study of methyl methacrylate polymerization in the presence of a bifunctional initiator, viz. N,N′-bis[(4-t-butylazo-4-cyanovaleryl) The activation energy of the first step in thermal decomposition has been determined (Ed = 74.5 kJ/mol) using the gas chromatographic method. A dilatometric study led to the reaction order with respect to the initiator, as well as the overall activation energy of polymerization (E = 78.5 kJ/mol).
