摘要
采用反气相色谱法(IGC)测定了对苯二甲酸丁二醇酯-己内酯(PBT-PCL)多嵌段共聚物与溶剂的Flory-Huggins相互作用参数和色散成分的表面能γdS,研究了温度对γSd的影响.同时,通过探针分子测得聚氯乙烯(PVC)与PBT-PCL共混时的相互作用参数χ为-0.796,结果表明,该共混物是相容的.
In this paper, the Flory -Huggins interaction parameter and surface energy γs^d of the dipersive component of the butylene terephthalate -ε - caprolactone ( PBT - PCL) copolyester was determined by inverse gas chromatography. The effects of temperature on γs^d values was discussed. The Flory - Huggins interaction parameter χ of PBT - PCL/PVC blend was - 0. 796 by calculation. The result indicates that the blend is miscible.
