摘要
用元素分析、红外光谱、X射线衍射及热分析等手段对硫磺溶液法合成的聚苯硫醚(PPS)树脂原粉、挤出切粒粒料及注塑制品进行了结构和热性能表征,并测定了加工前后PPS的溶液粘度变化。结果表明,加工后PPS的化学组成、链结构及聚集态结构与树脂原粉一致。说明硫磺溶液法合成的PPS具有良好的加工稳定性;加工后PPS的粘度和热转变行为发生了小的变化,本文从加工过程对低聚物及结晶度的影响角度给予了解释。
In this paper polyphenylene sulfide(PPS) manufactured by 'sulfur solution route''before and after processing has been comparatively investigated by inherent viscosity measurement .elemental analysis, infrared and X-ray diffraction spectra and thermal analysis. The results shown both the extrudates and injection moldings were possessed of the same structures as the virgin polymeric powder. From this results we conclude that the PPS obtained by 'sulfur solution route' has excellent stability during pnocessing. The slight changes of inherent viscosity and thermal transition behavior have also been observed and discussed.
