-5- 520386 A7 B7 V. Description of the invention (3) (Please read the notes on the back before filling this page) Acrylonitrile-butadiene-styrene (ABS) is a tough and hard plastic material, which has been widely used. Land is used, for example, in automotive parts, building materials, and home appliances. However, ABS is far more expensive than General Purpose Polystyrene (GPPS). Until the filing of this case, AB S has consistently been more expensive than GPPS over the past decade. The spread between ABS and GPPS is approximately $ 150 to $ 200 per metric ton, as shown in Table 1 below. Products made in AB S are therefore more expensive. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, G P P S is less mechanical than A B S. However, it is known that when a styrene-butadiene block copolymer (S B S, which is an elastomer) is added to G P P S, the impact resistance of the G P P S blend reinforced by S B S can therefore be improved. Table 3 illustrates the different mechanical properties of A B S and two general S P S reinforced G P P S blends. As illustrated in Table 3, when G P P S is enhanced by 15 w t% S B S, the impact resistance is 0 · 42 f t — 1 b / i η. When the SBS content is increased to 30 w t%, the impact resistance is increased to 1.84. However, the disadvantage is that SBS is more expensive than AB S and therefore the cost of producing a GPPS blend enhanced by SB S may be higher than A B S, which is economically undesirable for plastic producers. As shown in Table 2, the total cost of producing a general S B S enhanced GPPS blend (with 12 wt% SBC and 88 wt% GPPS) is $ 946 to $ 1284 per metric ton. Referring to Table 1, the cost of AB S is $ 850 to $ 120.00 per male. Therefore, as far as cost is concerned, in general, G P P S enhanced by S B S is less competitive than AB S. Other related disadvantages are the general SBS-enhanced GPPS blend. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) " '-6-520386 Μ B7 V. Description of the invention (4) There is a layering Problems with weak melt seams, poor coloration and low surface hardness. These problems are caused by the incompatibility between S B S and G P P S. As discussed above, the impact resistance of a general S P S-enhanced G P P S blend increases as the S B S content of the blend increases. However, increasing the S B S content inevitably increases the total cost of the blend because S B S is relatively expensive. It should also be noted that as the S B S content in the S P S enhanced G P P S blend increases, the tensile strength is reduced. For example, as can be seen in Table 3, when the S B S content is increased from 15 wt% to 30 wt% in the S B S-enhanced GPPS blend, the tensile strength is reduced from 5450 ps i to 3300 ps. Referring to Table 4, it is shown that the surface hardness of a general S P C reinforced G P P S blend decreases as the S B S content in the blend decreases. The low surface hardness of the S P S reinforced G P P S blend makes the final product easily scratched, for example, by nails. When the S B S content is maintained at substantially 20 w t%, the surface hardness is Rockwell 8 4 R. When the S B S content is maintained at substantially 10 wt%, the surface hardness is Rockwell 106R, which is close to ABS (ABS has a surface hardness of 109R). The surface hardness of Rockwell 10 9 R is not easy to be scratched. As discussed above, S B S does not have good compatibility with G P P S. This causes layering problems in the final product produced. The delaminated nature of the S P S enhanced G P P S blend also often causes problems during production. For example, studs for assembling screw posts or end products are formed in grooves in the mold cavity during injection molding. As the final product is demoulded after injection molding with its assembly screw posts or stiffeners, the base (or root) area (where the paper screws of the assembly screws are in accordance with Chinese National Standard (CNS) A4 specifications (210 × 297 mm)) (Please read first Note on the back then fill in this page) 丨 VI. 1. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -7-520386 A7 ______ B7_ 5. Description of the invention (5) (Please read the notes on the back before filling this page ) Columns or ribs extend from the injection molded product) are prone to break, so that such columns or ribs stick in the grooves of the mold cavity. This is because the strength of the base region is relatively weak. The weaker nature of the substrate region results from the layered nature of the SB P-enhanced G P P S blend material used. It is known in this field that it is extremely difficult to remove such assembly columns or stiffeners from the grooves of the mold cavity. Such removal will damage the mold 'and seriously interfere with normal injection molding production. Referring to FIG. 1, two objects made of a general S B S enhanced GP PS blend (87% GPPS and 13% SBS) are shown side by side. When the object on the right is broken, the fracture surface is quite sharp. The material incompatibility problem results in a% layered concrete structure, shown in the fracture surface, as shown in more detail in FIG. 2. It is known in the plastics industry that polymers with severe delamination problems cannot be used to make good products. (The objects shown in Figures 1 and 2 are injection molded by the Hong Kong Precision Spraying Laboratory. The injection molding uses a Negri Bossi NB2 150 metric ton clamping force injection molding machine. The material is made by using a twin screw with a screw diameter of 46 mm. The machine will be blended for the next time at 400 rpm. Use an extruder similar to Werner & Phleider.) The incompatibility of SBS and GPPS printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs also caused the above weakness. Problem with the weld seam line. Figure 2 shows the sharp edges of the fracture surface caused by weak melt seam line problems caused by the incompatibility of SBS and GPPS. During the manufacture of plastic products, the molten polymer is injection molded into the required shape and structure. A melt seam is an area where a blend of polymer melts from different directions flows and combines to form the final product. A weak melt seam problem means that in this area, plastic products can easily break on the melt seam. This & Zhang scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) '" " — ~ -8- 520386 A7 _____B7_____ 5. Description of the invention (6) (Please read the precautions on the back before filling in this Page) A further problem caused by SBS and GPPS incompatibility is the poor coloring performance of SBS-enhanced GPPS blend products. This is because the micro-reflection of the incident light caused by the delamination of the material results in a pre-blend of S P S-enhanced G P P S, which gives the manufactured product a pearlescent base color. Figure 3 shows a typical SBS-enhanced GPPS blend manufactured article. 0. 05wt% of the dye C. I. Solvent Blue 3 6 suitable for plastic blue was added to the blend ’thus produced. As can be seen, blue is a pearlescent base color. This feature is neither appealing nor desirable to the user. Products made from polymer blends according to the present invention have significant advantages in some respects over AB S and general S P S enhanced GP P S blends. The present invention provides a novel polymer blend including S B S 'grafted polystyrene (HIPS) and GPPS as main components' and a method for preparing the same. Six examples are explained below. Example 1 The composition of a first example of a polymer blend according to the present invention printed by an employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economics is shown in Table 5. The method of making this polymer includes preparing the main SBS and compatibilizer t S The first step of the bulk mixture material (which serves as an intermediate component). The compatibilizer used in this example is a polybutadiene-grafted polystyrene resin (HlpS). 'Although other suitable compatibilizers may be used, including styrene-epoxy-monobutadiene -Styrene (s EBS) and polydimethylbenzene K (PP). In the first step of preparing the matrix mixture material, the national standard specification (2 × 297 mm j --- 9-520386 A7 B7 V. Description of the invention (7) 5 BS weight to compatibilizer (ie 剂 IPS) weight The ratio is about 3 3 ·· 1 7, although experiments have shown that this ratio can be from 3: 2 to 4: 1 (also (please read the precautions on the back before filling this page), that is, 60% to 80% in the parent mixture % In the preferred range of SBS) or even in the wider processable range of 1 ·· 4 to 4: 1 (ie, 20 wt% to 80 wt% of SBS in the parent mixture). In this example The butadiene content in the SBS used is essentially 6 Owt%, although experiments have shown that the butadiene content in the SBS can advantageously be in the range of 4Owt% to 70% by weight or even in the wisdom of the Ministry of Economic Affairs The property bureau employee consumer cooperative prints a wide processable range of 2 Ow t% to 7 Ow t%. In this first step, SBS and Η IPS are first blended together to highly disperse SBS with Η IPS. This dispersion can be achieved by the twin-screw extrusion method commonly known in the plastics industry, although other methods can also be used Appropriate blending method. The goal of dispersion is to completely blend SBS and compatibilizer (that is, IPS in this example), so that SBS is uniformly dispersed in the matrix of the matrix mixture material, and SBS and GPPS Compared with the blend, SBS and Η IPS have better compatibility with each other and Η IPS acts as a good compatibilizer in the matrix mixture material to enhance the strengthening properties of SBS. As indicated above, other phases can also be used Capacitors such as s EBS and PP. However, s EBS and PP 0 are more expensive than IPS, so it is less cost-effective to use SEBS and PP 0 as compatibilizers in the preparation of matrix mixture materials. In addition to cost considerations In addition, the compatibilizer used must be safe in contact with food so that at least FD A approval is obtained. Traces of other additives (such as coupling agents, cross-linking agents, peroxides or other compatibilizers), such as this The artist's paper size is suitable for the Chinese National Standard (CNS) A4 specification (210x297 mm) ~~ -10- 520386 A7 ____ B7 丨 丨 _-One-five, the invention description (8) Known, can also be here at first Added in the blending step. This method also includes further combining the parent mixture material with ingredients including at least GPPS and additional Η IP s to form the final polymer blend. In addition to using additional Η IP s, it can also be used Additional SEBS and / or P PO. The amount of the precursor mixture material prepared in the first step may suitably account for 10% to 13% by weight of the final polymer blend, and G PS may be suitably used as 7% of the final polymer blend. wt% to 75wt%, and Η IPS can be used as the final polymer blend of 15wt% to] _7wt%. However, experiments have shown that it is also possible to use 5w t% to 2 5wt% of the master mix material, 3 Owt% to 9 Owt% of GPPS and 5wt% to 50. In other words,-effective range is from 1/8 to 5/6 . At this step, the weight of the IPS is relatively wide. The weight of the parent mixture material (please read the precautions on the back before filling this page). The Intellectual Property Bureau of the Ministry of Economic Affairs and the Consumer Cooperatives printed this GPP S weight step. Blending can be performed by general injection molding or extrusion, although other suitable methods can also be used. It is also possible to use highly dispersed static mixing nozzles to improve the dispersion of the matrix mixture materials, GP P S and Η I P S. Trace additives (such as color additives) can also be added during this blending step to improve the color of the product made from the final polymer blend. For example, 0.5 · w t% zinc stearate can be added as an external lubricant. Other additives such as those selected from the group consisting of amidine (A MID E WAX) and lignite (MOTANICWAX) can be added together with the parent material, g ρ p S and Η I P S to form the final polymer blend. It should be noted that the above examples utilize a two-step blending method. The first step of blending SBS with Η IPS can obtain a higher dispersion of SBS in the matrix mixture material. This paper is also applicable to China National Standard (CNS) A4 (210 × 297 mm) -11-520386 A7 B7 5 2. Description of the invention (9) Because SBS and HIPS have higher compatibility than SBS and GPPS. The second blending step enables the SB S obtained in the first step, which has been dispersed in the matrix mixture material, to be well mixed with GPP S and Η I P S. In the conventional one-step blending of S B S and GPP S, S B S cannot be dispersed with a degree of confidence 'because S B S and GP p S are incompatible. In this example of the present invention, the advantage of using the above two-step blending method is that S B S can be highly dispersed at first and the overall cost in blending is significantly reduced. The explanation is as follows: · Suppose the blending cost of producing one metric ton of polymer blend (such as a general PSB polymer blend reinforced with SB S) is $ X. There will be a further $ Y cost, i.e. when using a general polymer blend to produce the final product via, for example, injection molding. The total cost in blending and subsequent injection molding is therefore $ (X + Y). On the other hand, the novel polymer blend of this example includes 10% to 13% by weight of the parent mixture material, and a parent mixture material (0.10X to 0.13X metric tons) is prepared for use in making When a metric ton of polymer blend is used for subsequent injection molding, its blend cost is therefore $ (0.1 X) to $ (0.13 X). Because any injection molding process is related to the weight of the material, the costs associated with injection molding (that is, $ Y) cannot be avoided. According to the two-step blending method of the present invention, the overall blending cost is substantially saved because when using the In the method, the total blending cost is from $ (0 · 10 X + Y) to $ (0 · 13 X + Y), which is obviously less than $ (X + Y).

The advantages of the novel polymer blends made according to the present invention (illustrated by way of example, ie, Examples 1 to 6) are discussed below and are summarized in Tables 6 to 8 and FIGS. 6 to 8 The first advantage of the novel polymer blend of the present invention over conventional GP ps blends reinforced by sbs is their improved impact resistance and elongation at break. As shown in Table 6. Table 6 summarizes the experimental results obtained by different mechanical tests of the G p ps blend generally enhanced by S B S and the novel polymer blend made according to the present invention.

Two novel polymer blends made according to the present invention are better than ordinary G pps blends enhanced by S β S (0.42 ft 1 1 b / in) has higher impact resistance (0.81 ft-lb / in and 0.86it-lb / in). It can also be seen that the polymer compound of the new member has higher elongation at break (46.2% and 44.2%) than the general blend (34%). With reference to Table 7, it is shown that the novel polymer blend made according to the present invention is sized according to the Chinese National Standard (CNS) A4 (210X297 official celebration) -14-520386 A7 B7 V. Description of the invention (d (please first (Please read the notes on the back and fill in this page) The material has a higher surface hardness than the general SBS-reinforced GPPS blend. The surface hardness directly affects the scratch resistance of the product. ABS has the equivalent of Shore D 7 9 High surface hardness and the products made therefrom are not prone to scratches. For example, when scraping with nails, there are often no scratches on ABS products. Although the surface hardness of the novel polymer blend is Shore D77 It is not as high as ABS. Products made from novel polymer blends have substantially higher scratch resistance than ordinary SBS-reinforced GPPS polymer blends. They have 13 wt% SBS and 8 7 wt% GPPS general SBS-reinforced GPPS blends have a surface hardness of Shore D74 · 5. On the other hand, the novel polymer blends made according to the present invention (such as 10 wt% to 1 3 wt% Matrix mixture material, of which The ratio of SBS to Η I PS is 33 to 17) with a total SBS content of 6.6 wt% to 8.58 wt%, which is substantially lower than the SBS content in a typical polymer blend reinforced with s BS. Under the use of less elastomer SBS, the novel polymer blend made according to the present invention has higher surface hardness and is less likely to be scratched by, for example, nails. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 a, 4b and 5, Figure 4b is a novel polymer blend made according to the present invention (13 wt% of the parent mixture material, 17 wt% of Η IPS [Styron 470, Dow Chemical] J 7 0 wt% GPPS CDOW666H ], Where the matrix mixture material includes 66 wt% SBS [Tufprene A, Asahi Chemical] and 34 wt% HIPS [Styron 470, Dow Chemical].

Description of the invention (β table, which is shown as a synthesis according to the present invention In the making of polymer blends The polymer morphology of the parent mixture material of the intermediate components. These samples were obtained at the Hong Kong University of Science and Technology using a Zeiss optical microscope and the products shown therein are borrowed from a Negri Bossi NB2 150-ton injection molding machine (with a sulzer static mixing nozzle, this nozzle has 4 Mixing elements) molding. The product was cut by a Leica microtome at a temperature of -60 ° C and had a thickness of 1 micron. As can be seen in Figure 4a, the polymer morphology has a well-dispersed pattern (in its matrix), demonstrating that SB S and Η I P S are highly compatible with each other. As can be seen in Figure 4b, the polymer morphology has a well-dispersed morphology (in its matrix), which indicates that SBS, HIPS, and GPPS are highly valley-like. Figure 5 is a magnified photograph of the polymer form of the product produced by a general PSB blend reinforced with GPS, using a 46-mm twin-screw extruder at a speed of 40 rpm, also produced at the Hong Kong University of Science and Technology. This polymer morphology reveals that S B S and G P P S are not compatible with each other. The micro-layered structure is also shown in Figure 5. S B S is not highly dispersed in a matrix of a general PSB-enhanced G P P S blend. Referring to Fig. 4a and Fig. 4b, it can be seen that the polymer morphology shown in Fig. 4a has a smaller particle diameter, and the polymer morphology shown in Fig. 4b has a larger particle diameter. In the parent mixture material, the absence of GP Ps and the high shear force accompanying the production process of the parent mixture material form a polymer form of "smaller particles". On the other hand, in the production of a polymer blend added with G P P S and other Η I P S, conventional injection molding is used, so the shear force is low. As a result, as shown in Fig. 4b, the polymer morphology of > larger particles is shown. It should be noted that although the particle size shown in Figure 4b applies to the Chinese National Standard (CNS) A4 specification (210 father 297 mm), please read the precautions of fir first, and then print it at the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Consumption Cooperative. -16- 520386 Printed by the Consumer Cooperatives, Bureau of Intellectual Property, Ministry of Economic Affairs, this paper is printed in accordance with Chinese National Standard (CNS) A4 (210X297 mm) A7 B7

V. Description of the invention (U is larger than what is shown in Figure 4a. There are really smaller particles in the polymer. This is SBS embedded in the Η IPS and GP PS matrix. The SBS particles have been dispersed in the matrix mixture. In the material, as shown in Figure 4a. It should also be noted that once the SBS as an elastomer has been dispersed in the matrix, its enhancement function in the final polymer blend (or matrix mixture material) has been reached and strengthened The polymer morphology shown in Figures 4a, 4b, and 5 is easily understood by those skilled in the art. In other words, in order to achieve the same reinforcing effect, only the polymer blends prepared according to the present invention need to be used. Less SBS. Another advantage of the novel polymer blends made according to the present invention is lower cost than ABS and general SBS-enhanced GP ps polymer blends. Referring to Figure 8, Production Example 5 ( l0wt% 8: 68 and 111.8 parent mixture materials, 17 ~ 1% HIPS and 73wt% GpPS) and Example 3 (i3wt% SBS and HIPS parent mixture materials, i7wt% HIPS and 73wt% GPPs) The average cost per ton of novel polymer blend is 7 7 6 to 1 USD 7 4 USD 9 7 to USD 1095. In other words, compared to ABS, the cost reductions in producing novel polymer blends are approximately 8.7% to 丨 0.5% & 6.2% to 8. 75%. This is an attractive cost reduction in the plastics industry and the novel polymer blends made according to the present invention are extremely acceptable in industry.

Description of the invention (Ding's polymer blend essentially includes 8.6 wt% SBS, (Please read the precautions on the back before filling out this page) 2 1.4 wt% HIPS and 70wt% GPPS, And trace amounts (approximately 0.55 wt%) of blue dye (CI Solvent blue 36). As can be seen, the product in Figure 6 does not have a pearlescent base color, and when compared with the product not shown in Figure 3 'where Does not show pearlescent base color. The absence of pearlescent base color is due to the higher compatibility and dispersion of SBS in novel polymer blends, which makes better color matching possible. Back to Figures 7-8 and 2, Fig. 7 is a photographic representation showing a second product made of a polymer blend according to the present invention. Fig. 8 is a photographic representation showing a fractured surface of the product shown in Fig. 7. The product is novel as described above. The two-step blending method is used to mold and includes 1 3 wt% of the master mix material, 17 wt% of HIPS and 70 wt% of GPPS. The molding is made by Negri Bos si NB2 150 ton clamping force injection molding machine at Hong Kong Precision Injection Laboratory Limited Implementation. Same as the general SBS enhancement shown in Figure 2. Compared with the fracture surface of the object made by the GPPS blend, the fracture surface shows a more affinity pattern. In Figure 8, the layering problem is substantially improved. Referring to the edges of the fracture surface shown in Figure 8 and Figure 2, It can be seen that the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the edges of the fracture surface of the object in Fig. 2 to be sharper than the edges of the fracture surface of the object shown in Fig. 8. This is because of the blending of the novel polymer according to the present invention. The strength of the melt seam line in the product made by the product (shown in Figure 8) has been improved. As can be seen, the novel polymer blend prepared according to the above-mentioned two-step blending method of the present invention has a higher ratio than ABS. And general GPPS blends enhanced by s BS have several advantages, such as cost and excellent color matching.
