Thermal degradation of polymers. XII. Synthesis, polymerization and thermal characterization of polymers of m-N,N-dimethylaminostyrene in nitrogen



The monomer m-N,N-dimethylaminostyrene has been synthesized from acetophenone and homopolymerized and copolymerized with styrene, using 2,2′-azobisisobutyronitrile as free-radical initiator. The polymers have been characterized by thermal analysis (DTA, DSC, and TG). Glass transition temperatures have been measured and activation energies for degradation in nitrogen have been established by a variety of methods for comparative purposes.
