Abstract
The afterpolymerization of nylon 6 was carried out in three different reaction conditions, nitrogen flow, sealing and evacuation. The viscosity and reduced weight of polymer were increased by increasing the reaction time and temperature, and viscosity of polymers at constant reaction temperature was decreased as the following order: nitrogen flow >sealing >evacuation. The activation energy of afterpolymerization was 10.5 kcal/mole.
Nylon 6 의 후중합 반응을 질소흐름, 밀봉 및 감압의 세조건하에서 행하였다. 각 조건에 있어서 점도와 중합물의 감량은 반응온도 및 반응시간에 따라 증가하였고, 같은 반응온도에서의 점도는 감압, 밀봉, 질소흐름의 순서로 증가하였다. 후중합의 activation energy는 10.5kcal/mole로 계산되었다
