Abstract
Sorption experiments of n-hexane in cis-polybutadiene demonstrate that sorption behavior is Fickian with a diffusivity of 9.65 × 10-7 (㎠/sec). Differential sorption experiments yield the sorption isotherm at 25℃, which may be adequately described by Flory-Huggins theory with χ=0.58. The n-hexane diffusivities are concentration-dependent and analyzed in terms of Fujita''s free volume theory.

cis-폴리부타디엔에서의 n-헥산의 흡수실험결과는 확산속도가 9.65×10-7(㎠/sec)인 Fickian이였다. 미분흡수실험 결과로 부터 용해도 곡선을 얻었으며, 이는 Flory-Huggins (χ=0.58)이론식과 일치하였다. 아울러 n-헥산의 확산속도는 농도의 함수로 나타났으며, 이를 Fujita의 자유부피이론으로 설명하고 필요한 상수를 구했다.
