摘要

Synthesis and characterization of the copolymers (PAG) of -methyl styrene (AMS) and glycidyl methacrylate (GMA) are presented. The copolymers of PAG were characterized by gel permeation chromatography (GPC)

Fourier transform infrared spectroscopy (FTIR)

nuclear magnetic resonance (1H-NMR) and thermogravimetery (TG). Based on the copolymer compositions determined by 1H-NMR

the reactivity ratios of AMS and GMA were found to be 0.105 0.012 and 0.883 0.046 respectively by Kelen-Tds method. TG revealed that thermal stability of the copolymers decreased with increasing the AMS content in the copolymers

which indicated that the degradation was mainly caused by the chain scission of AMS-containing structures. Under heating

the copolymers depolymerize at their weak bonds and form chain radicals

which could further initiate other chemical reactions.
