According to the recent trend of reducing the weight of automobiles, the demand for high rigidity, high heat resistance and high chemical resistance polymer materials is increasing. PPS, one of the engineering plastics that satisfies these conditions, is thermally stable and has excellent properties such as high mechanical properties and high chemical stability, but it has the disadvantage of low fluidity to produce parts by injection molding. In this study, polyamide-based polymers, an engineering plastic, were synthesized to improve the fluidity of PPS. The synthesized polyamide was synthesized using dicarboxylic acid having a phenyl thioether group similar to the core structure of PPS and 3 types of diamine. The degree of fluidity improvement of the specimen using the synthesized flow regulator was analyzed by measuring the viscosity after making a disc using a micro-compounder to analyze the relationship of rheological properties according to the structure of the flow regulator. |
