氯化聚丙烯溶度参数的研究

Research of the solubility parameter of the chlorinated polypropylene

氯化聚丙烯是对聚丙烯材料有很好的粘结力 ,为了进行基础的应用研究 ,用浊度法对其溶度参数进行了测定 ,得到其溶度参数为 16 .72～ 2 1.15 (J/cm3 ) 1/ 2 。氯化聚丙烯溶解性能实验表明 :氯化聚丙烯属于弱极性物质。在溶度参数接近时 ,一般弱极性溶剂为良溶剂 ,中等极性溶剂为微溶溶剂。还用三维溶度参数对CPP的溶解性能进行了讨论。

The chlorinated polypropylene (CPP) has good cohering ability to the polypropylene materials. In order to carry out the research of its application, its solubility parameter, which was 16.72～21.15 (J/cm3)1/2,was determined with the method of turbidity. The studies of the dissolving properties of CPP in various solvents show that CPP is a weakly polar materials. The dissolving abilities of the weakly polar solvents are good to the CPP and ones of the moderately polar solvents are slightly dissolving at the case of the similar solubility parameters. At the same time, the dissolving properties of CPP was also discussed with three dementions of the solubility parameter.
