Abstract
고체상태에서 poly-ε-caproamide의 후중합과 해중합을 질소흐름 및 밀봉의 두 조건하에서 행하였다. 중합도는 반응시간과 온도에 따라 증가하여 결국 평형에 도달하며, 산소의 존재하에서는 산화에 의해 해중합되어 중합도가 감소하게 된다. 중합도가 서로 다른 poly-ε-caproamide를 반응시키면 평행에 도달했을 때의 중합도는 동일하게 된다.

The afterpolymerization and depolymerization of poly-ε-caproamide in solid state have been studied under two different reaction conditions, nitrogen flow and sealed state. The degree of polymerization (P) of nylon 6 increased with the increase in reaction time and temperature, and then reacted finally an equilibrium. In the presence of oxygen, P decreased by increasing the reaction time due to the oxidation reaction. Under certain reaction condition, the change of P for different initial degree of polymerization (P0) tendered toward unity in equilibrium.
