The equation of polymerization rate of glycine NCA in acetonitrile, initiated by n-butylamine, was expressed as the first order with respect to monomer and initiator concentrations, respectively. Two stage rate profile was observed : the fast first stage (50 minutes after initiation) and followed by slow second stage. The reaction rate constants were determined for fast and slow stage reactions. The activation energies in fast and slow rate step were 3 kcal/mole and 4 kcal/mole, respectively. The mechanism of chain growth was also discussed.

Acetonitrile 중에서 n-butylamine에 의해 개시되는 glycine NCA의 중합속도는 모노머 및 개시제농도에 각각 1차였다. 이 반응속도는 느린 단계와 빠른 단계인 2단계속도곡선을 나타내며 각 단계에서의 속도정수를 구하였다. 속도가 빠른 단계에서의 활성화에너지는 3kcal/mole이고 느린 단계에서의 활성화에너지는 4kcal/mole이었다. 또한 이 중합반응의 성장기구를 검토하였다.
