Abstract:

The kinetics of the copolymerizing process of octadecyl methacrylate, styrene and maleic anhydride were  performed by using the react IR analytical system (React IRTM4000), and the heat flow derived from exothermic copolymerization was measured by an Auto-RC reaction calorimeter. The results showed that the absorbance of functional groups, i.e. ester, anhydride, and phenyl remained stable. The change of the absorbance with time corresponded to the ternary addition copolymerization control region when the CC bond was broken.  The initiator required a certain inductiona period. There was an apparent exothermic reaction zone in the additional  polymerization, while  reaction was relatively stable and moderate. Therefore, this study could provide the reference for the determination and optimization of  key control parameters of the synthesis process.
 

Key words: octadecyl methacrylate-styrene-maleic anhydride terpolymer, the react IR system, reaction calorimeter
