摘　　要：用激光浊度法成功地测定了氯化度30%的氯化聚丙烯的溶解度参数,得到其溶解度参数范围在15.89~20.40(MJ/m^3)1/2。试验结果表明:激光浊度法不但可以在指定温度下精确测定不同相对分子质量氯化聚丙烯的溶解度参数,而且可以动态追踪整个试验过程,形象地给出聚合物溶解度的参数范围。该方法操作简便,测定精度高,是一种测定聚合物溶解度参数的新途径。The solubility parameters of the chlorinated polypropylene （ CPP ） with 30% chlorine content was successfully determinated by the laser turbidity method. And its solubility parameters were obtained in the range of 15.89-20.40（ MJ/m3 ）1/2. The test results showed that the laser turbidity method could not only accurately determine the solubility parameters of CPP with different relative molecular weight under the specified temperature, but also could dynamically track the whole experiment process and give the solubility parameter range of the polymer. This method has advantages of easy to operate and high precision, and it is a new way to determinate the solubility parameter of the polymer.
