摘要
用FTIR、DSC等方法研究了含噁唑啉官能团的聚苯乙烯(RPS)与氯化聚乙烯(CPE)之间的反应。RPS、CPE、PS、PE在不同温度下用反应式挤出机熔融共混。结果表明,RPS/CPE对PS/PE共混物具有增容作用,提高了共混物的力学性能。此反应性共混适宜在较低温度下进行。对RPS/CPE共混物还进行了动态力学表征,并与RPS进行比较以进一步了解共混物的特征。
The reaction between polystyrene having oxazoline groups(RPS) and chlorinated polyethylene(CPE) was investigated by FTIR, DSC methods. RPS,CPE,PS and PE were melt blended in a reactive extruder at different, temperature. Theresultsshow that RPS/CPE blends have compatibilizing effect to PS/P-E blends and improve their mechanical properties, lower temperature of melt extrusion is available to RPS/CPE reactive blending. Dynamic mechanical properties of RPS/CPE blend was examined and compared with the RPS in order to better characterize the blend.
