Embodiment 1 to 13 and comparative example 1 to 3
[0203]The conductive PPS resin composition to be tested was pelletized and injection molded at a resin temperature of 320°C and a molding temperature of 150°C to form a molded article. The notched Izod impact strength of each molded sample was determined according to ASTM D256. Notched Izod Impact Strength (Examples 33 to 42 and Comparative Examples 5 to 6):
Embodiment 33 to 42 and comparative example 5 to 6
[0204] The conductive PPS resin composition to be tested was pelletized and injection molded into molded articles at a resin temperature of 50°C higher than the melting point of the thermoplastic resin (F) and a molding temperature of 80°C. The notched Izod impact strength of each molded sample was determined according to ASTM D256. Inner Surface Smoothness (Examples 1 to 13 and Comparative Examples 1 to 3):
[0205] The condition and roughness of the inner surface of each tube sample was visually inspected. Surface smoothness (Examples 33 to 42 and Comparative Examples 5 to 6):
[0206] The granulation of the resin composition to be measured is placed in the C-5059D2-1 type melt indexer (aperture is 0.0825 inch, hole length is 0.315 inch) that Dongyang Seiko Company produces, and the thermoplastic The melting point of the resin was kept at a temperature of 60°C for 5 minutes, and then extruded under a load of 5Kg to obtain a blind tube. Effectively performing this operatio...
reference example 1
[0209] Ten tube samples with a length of 30 cm were placed in a cold vessel at -40°C for 4 h. The tube samples were then taken out of the cold vessel, and a ball weighing 0.454 Kg was dropped onto each tube sample from a height of 304.8 mm to check whether the tube sample was broken. Reference Example 1: Polymerization of PPS resin
[0210] Sodium sulfide 9 hydrate (6.005Kg, 25 moles), sodium acetate (0.205Kg, 2.5 moles) and N-methyl-2-pyrrolidone (hereinafter referred to as NMP) (5Kg) are placed in an autoclave with a stirrer, After gradually heating to 205°C and introducing nitrogen into the kettle, water (3.61) was distilled off. Next, the kettle was cooled to 180° C., and 1,4-dichlorobenzene (3.719 Kg, 25.3 moles) and NMP (3.7 Kg) were added. Then, the autoclave was sealed and heated to 270° C. under nitrogen, and reacted at this temperature for 2.5 h. After cooling, the reaction product was washed 5 times with lukewarm water, and dried at 80° C. for 24 h under reduced ...
