Embodiment 1、2
[0223] Use PA6 resin as thermoplastic resin (A), use GMA modified PE copolymer as resin (B) with reactive functional groups, mix according to the mixing composition shown in Table 1, remove volatile components by vacuum pump and blow in nitrogen flow , while using a screw diameter of 37mm and a screw rod of 2 threads with L / D0=100 co-rotating fully intermeshing twin-screw extruder (manufactured by Toshiba Machine Co., Ltd., TEM-37BS-26 / 2V), in Melt-kneading was carried out at a cylinder temperature of 260° C. at the screw speed and extrusion rate shown in Table 1, and a rope-shaped molten resin was discharged from a discharge port (L / D=100). At this time, the coloring agent was added simultaneously with the raw materials, and the time when the coloring of the extruded product reached the maximum was measured as the residence time. The residence time is shown in Table 1. In addition, the screw structure: as A, there are seven kneading zones starting from the positions of L / D0=2...
Embodiment 3
[0229] From a co-rotating fully intermeshing twin-screw extruder (manufactured by Toshiba Machine Co., Ltd., TEM-37BS-26 / 2V) with a screw diameter of 37 mm and a screw diameter of 2 screws with L / D0=100. The thermoplastic resin composition was obtained by melt-kneading in the same manner as in Example 1 except that the sampling valve of L / D0=72 discharged the thermoplastic resin composition. The kneading conditions are shown in Table 1, and the evaluation results of the obtained thermoplastic resin compositions are shown in Tables 2 and 3. In addition, if calculated by (total length of kneading zone)÷(total length of screw)×100
[0230] From the ratio (%) of the total length of the above-mentioned kneading zones to the total length of the screw, the ratio (%) of the total length of the kneading zones is 15%.
Embodiment 4、5
[0242] Use PA6 resin as thermoplastic resin (A1), use GMA modified PE copolymer as resin (B) with reactive functional groups, mix according to the mixing composition shown in Table 4, remove volatile components by vacuum pump and blow in nitrogen flow, using a screw diameter of 37mm and a co-rotating fully intermeshing twin-screw extruder (manufactured by Toshiba Machine Co., Ltd., TEM-37BS-26 / 2V) with L / D0=100 of 2 screws with 2 threads. , Melt-kneading was carried out under the cylinder temperature of 260° C., the screw speed shown in Table 4, and the extrusion rate conditions, and the rope-shaped molten resin was discharged from the discharge port (L / D=100). At this time, the coloring agent was added together with the raw materials, and the time when the coloring of the extruded product reached the maximum was measured as the residence time. The residence time is shown in Table 4. In addition, the screw structure: as A, there are seven kneading zones starting from the posit...
