2-Benzamidoacrylic Acid의 자유라디칼 중합에 관한 연구
이종광,정판석 慶尙大學校 기초과학연구소 1987 基礎科學硏究所報 Vol.3 No.-
The free-radical polymerization of 2-benzamidoacrylic acid and the thermal properties of poly(2-benzamidoacrylic acid) were investigated. Polymerization of 2-benzamidoacrylic acid initiated by AIBN has been studied in DMF at 60±0.1℃in nitrogen atmosphere. The initial rate of polymerization was found to be proportional to 0.52 power of AIBN concentration(5.0×10^-3 to 4.0×10^-2M) and 1.05 power of 2-benzamidoacrylic acid concentration(1.41×10^-1 to 1.13M). The overall activation energy for the polymerization was found to be 20.9 kcal/mol within the temperature range 50∼70℃. The DTA thermogram of poly(2-benzamidoacrylic acid) showed an endothermic peak for the first degradation at about 200℃ and an exothermic peak for the second degradation at about 368℃. The TGA thermogram for the first degradation showed that the weight loss was about 64% by decarboxylation at 350℃.
