Problems solved by technology

[0003] However, the crystallization rate of polyolefin-based resins after molding is slow, so there are disadvantages in that the molding cycle is low, and in addition, large crystals are formed due to the progress of crystallization after heating molding, and the transparency and strength are insufficient.
It is known that all these disadvantages originate from the crystallinity of polyolefin resins, and if the crystallization temperature of polyolefin resins can be raised to rapidly form fine crystals, the above problems can be solved

Embodiment 1-1～1-6、 comparative example 1-1～1-9

[0086] A phenolic antioxidant (tetrakis[methylene-3 -(3',5'-di-tert-butyl-4'-hydroxyphenyl) propionate] methane) 0.05 parts by mass, phosphorus antioxidant (tris(2,4-di-tert-butylphenyl) phosphorous acid 0.1 parts by mass of ester), 0.05 parts by mass of hydrotalcite (trade name "DHT-4A" manufactured by Kyowa Chemical Industry Co., Ltd.), and the compositions described in Tables 1 to 3 were mixed using a Henschel mixer at 1000 rpm x 1 minute Then, pelletizing was performed at an extrusion temperature of 230° C. using a twin-screw extruder. After drying the granulated pellets at 60°C for 8 hours, the flexural modulus and deflection temperature under load (HDT) were measured under the conditions described below. These results are shown in Tables 1-3, respectively. In addition, all the units of each component in a table|surface are mass parts.

Embodiment 2-1～2-2、 comparative example 2-1～2-8

[0088] A phenolic antioxidant (tetrakis[methylene-3 -(3',5'-di-tert-butyl-4'-hydroxyphenyl) propionate] methane) 0.05 parts by mass, phosphorus antioxidant (tris(2,4-di-tert-butylphenyl) phosphorous acid 0.1 parts by mass of ester), 0.05 parts by mass of hydrotalcite (trade name "DHT-4A" manufactured by Kyowa Chemical Industry Co., Ltd.), and the compositions described in Table 4 and Table 5 were mixed using a Henschel mixer at 1000 rpm x 1 minute Then, pelletizing was performed at an extrusion temperature of 230° C. using a twin-screw extruder. After drying the granulated pellets at 60° C. for 8 hours, the haze was measured under the conditions described below. These results are shown in Table 4 and Table 5, respectively. In addition, all the units of each component in a table|surface are mass parts.

Embodiment 3-1～3-7、 comparative example 3-1～3-7

[0090] A phenolic antioxidant (tetrakis[methylene- 3-(3',5'-di-tert-butyl-4'-hydroxyphenyl) propionate] methane) 0.05 parts by mass, phosphorus antioxidant (tris(2,4-di-tert-butylphenyl) Phosphate) 0.1 parts by mass, calcium stearate 0.05 parts by mass, crosslinking agent or peracid {2,5-dimethyl-2,5-bis(t-butylperoxy)hexane} 0.023 parts by mass , and the compositions described in Table 6 and Table 7 were mixed with a Henschel mixer at 1000 rpm for 1 minute, and then pelletized at an extrusion temperature of 230° C. using a twin-screw extruder. After drying the granulated pellets at 60°C for 8 hours, the flexural modulus and deflection temperature under load (HDT) were measured under the conditions described below. In addition, the melt flow rate of the granulated pellets was 40 g / 10 minutes. These results are shown in Table 6 and Table 7, respectively. In addition, all the units of each component in a table|surface are mass parts.
