摘 要: 用反向色谱、激光浊度等方法测定了氯化聚丙烯的相变温度、溶度参数、氢键力以及在不同溶剂中的溶解情况。结果表明 :氯化聚丙烯是一种非晶态的弱极性物质 ,软化点在 60~ 90℃附近 ;溶度参数约为 16 72~ 2 1 15 (J/cm3 ) 1/ 2 ;在溶度参数接近时 ,一般弱极性溶剂为氯化聚丙烯的良溶剂 ,中等极性溶剂为其微溶溶剂。 RP chromatography and laser-turbidity method were used to determinate the phase transformation temperature, solubility parameters, hydrogen-bond force and solubility in different solutions of CPP. The results showed that CPP was a weak polar material with phase transformation of 60~90℃ and solubility parameter of 16.72~21.15(J/cm 3) 1/2 . The solubility tests of CPP indicate when the solubility parameters are close, a general weak polar solvent is a good solvent for CPP, and a medial polar solvent is a weak solvent.
