5000 or more is required, preferably 2000053
There are 0000T. If the molecular weight is less than 15,000, there will be problems in practical strength such as impact strength, and if the molecular weight is 30,000 or more, fluidity will be impaired.

トは融点が２３０℃であり、ＡＢＳよりも優れた流動性
を有し、かつ加工温度範囲がほぼ一致しているという利
点を有する。Among the aromatic polyesters described in the prior art described above, polyethylene terephthalate and polybutylene terephthalate are known as popular crystalline aromatic polyester resins. However, polyethylene terephthalate has a melting point of about 260° C., and its fluidity is generally inferior to that of ABS, and its processing temperature range is too high. On the other hand, polybutylene terephthalate has the advantage of having a melting point of 230°C, superior fluidity to ABS, and almost the same processing temperature range.

剤としての効果がなく、１．５以下が望ましい。Polybutylene terephthalate (B) is a product obtained by condensation polymerization of terephthalic acid as a dicarzenic acid component and butylene glycol as a glycol component, and is (ortho)-
The intrinsic viscosity measured at 25°C using chlorphenol as a solvent is at least 0.5 or more, preferably 0.6 to 1.
5. If the intrinsic viscosity is lower than 0.5, the mechanical strength will be low, and if the intrinsic viscosity is too high, it will not be effective as a fluidity improver, so it is preferably 1.5 or less.

。The blending amount of polybutylene terephthalate (B) is 1
A weight ratio of 0 to 45 is required. If it is less than 10% by weight, there is little effect on improving fluidity, and if it exceeds 45% by weight, the molding shrinkage rate increases, making it unsuitable as a resin for precision molding.

係を越えると流動性が低下する。However, the acrylonitrile content in ABS is 20% by weight.
If it is less than that, the chemical resistance is poor. On the other hand, as for the rubber component, there are at least 10 polybutadiene and styrene-butadiene-based didistomers containing butadiene as a constituent unit! If it is less than f1%, impact resistance cannot be expected, and if it exceeds 45% by weight, fluidity decreases.
同様に耐衝撃性と流動性のバランスの点から全樹脂組成
物中のＡＢＳの含有量としては１５〜７０ぐわない。Similarly, from the viewpoint of the balance between impact resistance and fluidity, the content of ABS in the entire resin composition should be between 15 and 70.

For example, this can be achieved by mixing the resins in a tumbler-Henschel mixer or the like, and then melt-kneading them in a single-screw or twin-screw extruder at a temperature higher than the melting temperature of polybutylene terephthalate.
