本文用静态压电吸收法研究了苯乙烯对-(六氟-2-羟基异丙基)苯乙烯的共聚物(PHFA)对模拟毒气甲基膦酸二甲酯(DMMP)的吸收作用,用静态压电吸收法和反气相色谱法分别测定了PHFA与DMMP之间的Flory-Huggins相互作用参数X_(12)和X_(12)(IGC),发现X_(12)外推到DMMP浓度为零时所得的X_(12)~∞与PHFA中羟基的红外光谱吸光率呈线性关系,X_(12)随DMMP重量分数的增加而增大,X_(12)(IGC)与温度的关系符合X=α+β/Τ,且β为负值。
In this paper, the static piezoelectric absorption method was used to study the effect of PHFA on the absorption of DMMP. The Flory-Huggins interaction parameters X_ (12) and X_ (12) (IGC) between PHFA and DMMP were measured by static piezoelectric absorption method and anti-gas chromatography respectively. It was found that X_ (12) extrapolated to DMMP concentration of zero The linear relationship between X_ (12) ~ ∞ and the infrared absorbance of hydroxyl group in PHFA was obtained. X_ (12) increased with the increase of DMMP weight fraction. The relationship between X_ (12) α + β / Τ, and β is a negative value.
