Abstract
Dynamic mechanical properties and crystal structure of PVA/Borax complexes in the presence of gelatin were investigated by using IR, X-ray, Rheovibron, DSC and SEM and also annealing temperature and draw ratios. Dynamic modulus of PVA/Borax complexes was decreased with decrease of PVA crystal. The crystallinity of PVA in the PVA/Borax complexes in the presence of gelatin was decreased with structure deformation. Maximum crystallinity by annealing at 90℃ was obtained and crystallinity was increased with draw ratios.

젤라틴 존재 하에서 얻어진 PVA/붕사 복합체의 결정구조와 동력학적 성질에 관해서 연구하였다. 이들 복합체를 열처리와 연신된 필름으로 하여 IR, X-ray, DSC, SEM을 이용하여 측정한 결과 단독의 PVA에 비하여 PVA 결정이 파괴되어 구조변화를 나타냈으며 Rheovibron 측정결과 PVA 구조 변화에 기인하여 dynamic modulus 역시 급격한 감소를 보였다. 이들 복합체는 90℃에서 열처리되었을 때 최대의 결정을 얻었으며 연신비가 증가함에 따라서도 결정의 증가를 보였다.
