At the same time, when the content of the acrylonitrile monomer unit is increased, the yellow index is increased, indicating that the yellow color of the resin itself is heavier, and when the monomer unit of the propylene is 33.5 parts by weight, #加人When pentaerythritol tetrastearate is used, the I color index will rise even more. Therefore, the styrene-based acrylonitrile-based copolymer contains 3 to 35% by weight of the acrylonitrile-based monomer unit of 32 to 34% by weight. Referring to Figures 1 to 2, Figure 1 is a comparison of the mold release force in the case where the different weight parts of the esterified product are added in the first embodiment and the comparative example, and the second figure is the difference between the first embodiment and the comparative example.

In other words, the mold release force of the stupor-acrylonitrile-based copolymer resin composition of the present invention is about 150 to 280, the haze is less than about 1%, and the yellowness index is less than 12 5 . In the comparative example, in the case of 0.2 and 5% by weight of pentaerythritol tetrastearate, the mold release forces were 169.2 and 76.6, respectively, and in the case of 季2 parts by weight of pentaerythritol tetrastearate, The haze is 3 49%, and the κ color and number rise to about 22.5. Briefly, the release force of the comparative example is about 75 to 280, and the haze is about 3.49% in the case of using 0.2 part by weight of pentaerythritol tetrastearate. In other words, pentaerythritol tetrastearate is used. In the case of a higher part by weight of pentaerythritol tetrastearate, although the mold release force is lower and the demolding is simpler, the transparency is lowered and the resin is yellowish. However, the composition of the styrene-acrylonitrile-based copolymer resin of the present invention is 4, even in the case of adding an ester mixture of 0.5 part by weight of pentaerythritol, the haze is less than 1%' and at the same time having good properties.

In short, 'in every 100g of styrene-acrylonitrile-based copolymer resin composition, when pentaerythritol tetrastearate is less than about χ丨〇2χ丨〇_4m〇ie and pentaerythritol vinegar mixture The amount of hydroxide is, for example, greater than about 〇7xl (T4m〇le, after measurement, about 1% is obtained. One of the characteristics of the styrene-based acrylonitrile-based poly-resin composition of the present invention is characterized by The resin composition molded article of the present invention has a better performance for money by adding a specific mixture of pentaerythritol to the present invention. Briefly, the styrene-based acrylonitrile copolymer resin composition of the present invention has both mold release force and fog. The degree of consideration can make the resin molded article both in terms of mold release property and transparency. The styrene-acrylic-based copolymer resin composition of the present invention can be used as needed within a range that does not impair the effects of the present invention. Add various additions 1 Additives such as antioxidants, heat-resistant agents, light stabilizers, weathering agents, antistatic agents, compatibilizers, pigments, dyes, and fluorescent whitening agents, etc. The above are merely illustrative and not limiting. Any equivalent modifications or changes made to the spirit and scope of this creation shall be included in the scope of the appended patent application. [Simplified illustration] Figure 1 is the first example Comparative Example A comparison of mold release forces in the case of adding different parts by weight of esterified ester. 19 201226421 Fig. 2 is a graph showing the haze and ester addition weight of Example 1 and Comparative Example in the case of adding different parts by weight of esterified product. Comparison chart. Fig. 3 is a graph showing the relationship between the haze and the mole number of pentaerythritol tetrastearate. Figure 4 is a plot of haze and m〇le number of hydroxide. Figure 5 is a graph showing the relationship between the haze and the m〇ie number of pentaerythritol tetrastearate. Figure 6 is another plot of haze and mole number of hydroxide.
