description | Three kinds of thermal stabilizers for nylon 4 were synthesized to incorporate both hindered amine groups and methylene units with various lengths. It is expected that the hindered amine groups play a role in the capture of degradation-triggering species. Considering sequence rules, hydrogen bonding formed between nylon 4 and the stabilizers is optimized to alter the lengths of the methylene units in the stabilizers. As a result, it was found that a tetramethylene unit in the stabilizer is an optimal length for hydrogen bonding in terms of isothermal thermogravimetric analysis (TGA). Considering the slight and often negligible improvement of thermal stability of nylon 4 containing commercially-available nylon 6 stabilizers, retardation of thermal degradation has been substantially improved upon. 힌더드 아민기를 포함하고 있는 헤테로환을 가지며 알킬사슬 길이가 서로 다른 세 종류의 나일론 4 열안정제를 합성하였다. 힌더드 아민기를 이용하여 라디칼에 의한 열분해를 방지하고, 열안정제와 나일론 4의 아마이드기 간 수소결합을 조절하여 나일론 4의 열적 특성에 미치는 영향을 확인하였다. 안정제의 알킬사슬의 수가 4개일 때 수소결합이 가장 최적화되는 것으로 등온 TGA 결과를 통해서 확인하였다. 또한 시판중인 나일론 6의 열안정제를 사용하여 나일론 4에 대한 열안정성을 비교 실험한 결과, 합성 열안정제가 나일론 4의 열안정성을 실질적으로 향상시킨 것을 확인하였다. |
