Polyphenylene sulfide(PPS) based composite materials have been widely explored in various industries such as automobiles, electronics and construction due to their high chemical resistance, mechanical properties, thermal stability, economic properties and light weight. However, the high viscosity of polyphenylene sulfide has limited their processing efficiency in molding. Here, we synthesize linear structure additives with thioamide bonds between aromatic rings and alkyl chains. The thioamide in the additives allow outstanding miscibility with polyphenylene sulfides, resulting in high fluidity of the PPS. To demonstrate the fluidity enhancement of the PPS by introducing the additives, the length increase in injection molded spiral specimens and the viscosity decrease measured by a rotational rheometer, were shown. Also we prepared PPS/GF composites, including the flow modifiers, to study the mechanical properties. |
