[2] Evaluation of processing stability of thermoplastic polymer composition
[0222] The processing stability of the thermoplastic polymer compositions obtained in the following Examples and the like was evaluated by the method of the following (1) or (2).
(1) MFR Variation Rate
[0223] Dwell MFR tests were performed using the pellets of the thermoplastic polymer compositions. The test was based on JIS K 7210, and 0 min Dwell MFR (g/10 min) and 30 min Dwell MFR (g/10 min) were measured by a melt indexer (L217-E14011 manufactured by Technol Seven Co., Ltd.) under the conditions of temperature in a cylinder 270° C. and load 2.16 kg. The 0 min Dwell MFR was measured after 5-min preheating time after filling pellets of the thermoplastic polymer composition in the cylinder. The 30 min Dwell MFR was measured after 30-min dwell time, including the preheating time, of the pellets of the thermoplastic polymer composition in the cylinder. The MFR variation rate was calculated by the following formula and using the thus-measured 0 min Dwell MFR and 30 min Dwell MFR:
MFR variation rate (%)=absolute value of (30 min Dwell MFR-0 min Dwell MFR)×100/(0 min Dwell MFR)
[0224] A smaller MFR variation rate means better processing stability of the thermoplastic polymer composition.
(2) Inhibition Rate of MFR Increment
[0225] Dwell MFR tests were performed using the pellets of the thermoplastic polymer compositions. The test was based on JIS K 7210, and 30 min Dwell MFR (g/10 min) were measured by a melt indexer (L217-E14011 manufactured by Technol Seven Co., Ltd.) under the conditions of temperature in a cylinder 270° C. and load 2.16 kg. The 30 min Dwell MFR was measured after 30-min dwell time, including the preheating time, of the pellets of the thermoplastic polymer composition in the cylinder. The inhibition rate of MFR increment was calculated by the following formula and using the 30 min Dwell MFR obtained in the Example and the 30 min Dwell MFR of Comparative Example:
inhibition rate of MFR increment (%)=(30 min Dwell MFR of Comparative Example-30 min Dwell MFR of Example)×100/(30 min Dwell MFR of Comparative Example)
[0226] When polypropylene is used as a thermoplastic polymer, decomposition of polypropylene is accelerated by the heat of processing, and 30 min Dwell MFR increases. Therefore, in a thermoplastic polymer composition containing polypropylene, the processing stability of the thermoplastic polymer composition becomes higher as 30 min Dwell MFR is smaller and the inhibition rate of MFR increment is larger.
Production of Processing Stabilizer
[0227] Compound (1-1) and compound (9-1) in the amounts described in Table 1 were mixed to produce a processing stabilizer.
[0228] Compound (1-1), compound (9-1) and compound (2-1) in the amounts described in Table 1 were mixed to produce a processing stabilizer.
[0229] Compound (1-1) and compound (2-1) in the amounts described in Table 1 were mixed to produce a processing stabilizer.
[0230] The processing stabilizer obtained in Example 1-1 (0.31 part) and a styrene-butadiene block copolymer ("Asaflex 830" manufactured by Asahi Kasei Corp.) (100 parts) were dry-blended, the obtained mixture was knead-extruded by a single screw extruder having a screw diameter of 30 mm ("VS30-28 type extruder" manufactured by TANABE PLASTICS MACHINERY CO., LTD.) under the conditions of temperature 230° C. and screw rotation 50 rpm to give strands, and the strands were cut by a pelletizer to give a thermoplastic polymer composition as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 2.
[0231] In the same manner as in Example 1-3 except that compound (1-1) (0.3 part) alone was used instead of the processing stabilizer obtained in Example 1-1, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 2.
[0232] In the same manner as in Example 1-3 except that the stabilizer composition (0.51 part) obtained in Example 1-2 was used instead of the stabilizer composition obtained in Example 1-1, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 2.
[0233] In the same manner as in Example 1-3 except that the processing stabilizer (0.5 part) obtained in Reference Example 1-1 was used instead of the processing stabilizer obtained in Example 1-1, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 2.

[0234] From the results shown in Table 2, it is clear that a combined use of compound (1) and compound (9) improves the processing stability of thermoplastic polymer compositions as compared to a single use of compound (1). In addition, it is clear that the processing stability of thermoplastic polymer compositions is improved by using compound (9) in combination, even when compound (2) is used in addition to compound (1).

[0238] Compound (8-1) and compound (9-1) were mixed to produce a processing stabilizer.
[0239] The processing stabilizer (0.11 part) obtained in Example 2-1 and an ethylene-vinyl alcohol copolymer ("EVAL F171B" manufactured by KURARAY CO., LTD.) (100 parts) were dry-blended, the obtained mixture was knead-extruded by a single screw extruder having a screw diameter of 30 mm ("VS30-28 type extruder" manufactured by TANABE PLASTICS MACHINERY CO., LTD.) under the conditions of temperature 230° C. and screw rotation 50 rpm to give strands, and the strands were cut by a pelletizer to give a thermoplastic polymer composition as pellets.
[0240] In the same manner as in Example 2-2 except that compound (8-1) (0.1 part) alone was used instead of the processing stabilizer obtained in Example 2-1, a thermoplastic polymer composition was obtained as pellets.
[0241] The composition of the processing stabilizer obtained in Example 2-1 is shown in Table 5, and the compositions and the results of processing stability of the thermoplastic polymer compositions obtained in Example 2-2 and Comparative Example 2-1 are shown in Table 6.

[0242] From the comparison of Example 2-2 and Comparative Example 2-1, it is clear that a combined use of compound (8) and compound (9) improves the processing stability of thermoplastic polymer compositions as compared to a single use of compound (8).

[0246] Compound (2-1) and compound (9-1) in the amounts described in Table 9 were mixed to produce a processing stabilizer.
[0247] Compound (2-1), compound (9-1) and compound (1-1) in the amounts described in Table 9 were mixed to produce a processing stabilizer.
[0248] The processing stabilizer (0.21 part) obtained in Example 2-1 and a styrene-butadiene block copolymer ("Asaflex 830" manufactured by Asahi Kasei Corp.) (100 parts) were dry-blended, the obtained mixture was knead-extruded by a single screw extruder having a screw diameter of 30 mm ("VS30-28 type extruder" manufactured by TANABE PLASTICS MACHINERY CO., LTD.) under the conditions of temperature 230° C. and screw rotation 50 rpm to give strands, and the strands were cut by a pelletizer to give a thermoplastic polymer composition as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 10.
[0249] In the same manner as in Example 3-3 except that the stabilizer composition (0.51 part) obtained in Example 3-2 was used instead of the stabilizer composition obtained in Example 3-1, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 10.
[0250] In the same manner as in Example 3-3 except that compound (2-1) (0.2 part) alone was used instead of the processing stabilizer obtained in Example 3-1, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 10.
[0251] Compound (2-2) and compound (9-1) in the amounts described in Table 9 were mixed to produce a processing stabilizer.
[0252] In the same manner as in Example 3-3 except that the processing stabilizer (0.2 part) obtained in Example 3-5 was used instead of the processing stabilizer obtained in Example 3-1, and polypropylene ("NOBRENE" manufactured by Sumitomo Chemical Company, Limited) (100 parts) was used instead of a styrene-butadiene block copolymer, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 10.
[0253] In the same manner as in Example 3-6 except that compound (2-2) (0.1 part) alone was used instead of the processing stabilizer obtained in Example 3-5, a thermoplastic polymer composition was obtained as pellets. The results of the processing stability of the obtained thermoplastic polymer composition are shown in Table 10.

[0254] From the results shown in Table 10, it is clear that a combined use of compound (2) and compound (9) improves the processing stability as compared to a single use of compound (2). In addition, it is clear that the processing stability is improved by using compound (9) in combination, even when compound (1) is used in addition to compound (2).

[0258] Compound (3-1) (0.1 part) and compound (9-1) (0.01 part) were mixed to produce a processing stabilizer.
[0259] The processing stabilizer (0.11 part) obtained in Example 4-1 and polypropylene ("NOBRENE" manufactured by Sumitomo Chemical Company, Limited) (100 parts) were dry-blended, the obtained mixture was knead-extruded by a single screw extruder having a screw diameter of 30 mm ("VS30-28 type extruder" manufactured by TANABE PLASTICS MACHINERY CO., LTD.) at temperature 230° C. and screw rotation 50 rpm to give strands, and the strands were cut by a pelletizer to give a thermoplastic polymer composition as pellets.
[0260] In the same manner as in Example 4-2 except that compound (3-1) (0.1 part) alone was used instead of the processing stabilizer obtained in Example 4-1, a thermoplastic polymer composition was obtained as pellets.
[0261] The composition of the processing stabilizer obtained in Example 4-1 is shown in Table 13, and the compositions and the results of processing stability of the thermoplastic polymer compositions obtained in Example 4-2 and Comparative Example 4-1 are shown in Table 14.

[0262] By mixing the components described in Table 15-1-Table 15-4, processing stabilizers are obtained. These processing stabilizers are predicted to improve the processing stability of a thermoplastic polymer composition (that is, inhibiting MFR variation rate or increasing inhibition rate of MFR increment).
