摘要聚合物的溶解度数据可用于解决液相色谱中的各种问题。然而，由于手动和劳动密集型测量程序，聚合物溶解度的实验数据很少。应用新的连续测量程序可以方便、快速、非主观地测量聚合物的浊点数据。已测定了二元溶剂混合物中聚乙烯、聚丙烯和聚 1-丁烯的浊点。此外，还测量了聚乙烯在各种溶剂中的浊点温度。
SummarySolubility data of polymers are useful in solving various problems in liquid chromatography. Experimental data on polymer solubility is however, scarce due to manual and labour intensive measurement procedures. Application of a new continuous measurement procedure enables convenient, rapid and nonsubjective measurement of cloud point data of polymers. The cloud points of polyethylene, polypropylene and poly-1-butene in binary mixtures of solvents have been determined. Furthermore the cloud point temperatures of polyethylene in various solvents have been measured.
