摘要
反相气相色谱法(IGC)在聚合物研究中的应用已有综述。端羟基聚丁二烯(HTPB)是一种低聚物,广泛用于涂料、密封剂、固体火箭推进剂、聚合物共混改性等方面。目前,关于HTPB物理化学性质的研究较少,HTPB与溶剂的热力学相互作用的研究尚无报道。本文用IGC法研究HTPB与正戊烷等六种溶剂的热力学相互作用。
The thermodynamic interaction of hydroxyl-terminated polybutadiene (HTPB)with several solvents has been studied by using inverse gas chromatography.The retention volume of solvent probe was determined after considering its depen dence on the flow rate of the carrier gas and on the coterage of HTPB on the support.The interaction parameters xu,Xl2 and X12 were calculated.The results reflect some characteristic points of the interactoon between HTPB and solvents.
