摘要：

Glycidyl methacrylate (GMA) and alpha-methyl styrene (AMS) were copolymerized in different ratios under vacuum using azobisisobutyronitrile (ABIN) as initiator. The copolymers were characterized by gel permeation chromatography (GPC), IR and H-1-NMR spectroscopy. Their composition was determined by H-1-NMR analysis. Thermal degradation of copolymers was studied by thermogravimetery (TG), differential thermogravimetery (DTG) and differential thermal analysis (DTA) under inert atmosphere. The apparent activation energies for decomposition of the copolymers were calculated from their TG data and their thermal stability compared. (C) 2002 Published by Elsevier Science Ltd.
