ナイロン４６樹脂がこれらの優れた性質を示す理由とし

ナイロン６６樹脂、ナイロン６樹脂。The reason why nylon 46 resin exhibits these excellent properties is the melting point and crystallinity of common polyamide resins, such as nylon 66 resin and nylon 6 resin.

ナイロン４６樹脂が一般のポリアミド樹脂に比べて押出
・成形性が著しく劣るという原因にもなっている。It can be said that it shows a very high value when compared to something like nylon 12 resin, but this is also the reason that nylon 46 resin has significantly inferior extrusion and moldability compared to general polyamide resin. ing.

る。In other words, the fact that nylon 46 resin has a high melting point of about 290°C means that the resin temperature during extrusion and molding is 300°C.
As a result, it has the disadvantage that it is close to the thermal decomposition temperature of amide bonds (approximately 320°C), and the temperature range suitable for extrusion and molding is narrow. This means that more heat is required to melt it. This means that high plasticizing temperatures, long plasticizing times, and high crosstalk torques are required during extrusion and molding, which not only cause high costs but also ensure stable extrusion and molding. This may cause problems such as inducing thermal decomposition of the polymer.

脂の値６０〜７０℃に比べて特異的である。In general, moldability is important in the evaluation of plastics, and even if the plastic itself has inherently excellent properties, if the molding condition range is narrow, it will not only be impossible to economically manufacture the product, but also Attempts have been made to improve the moldability of nylon 46 resin by blending common polyamide resins such as nylon 6 resin, nylon 66 resin, and nylon 12 resin in products (Japanese Patent Laid-Open No. 61-64751). Publication, JP-A-61-15
6161, JP-A-60-248775, etc.). However, when these general polyamide resins are blended, a drawback arises in that the excellent heat resistance expressed by the heat distortion temperature of nylon 46 resin is significantly impaired. The heat distortion temperature of nylon 46 resin is a very high value of 230°C even without reinforcing material, which is higher than the value of 60 to 70°C for general polyamide resins such as nylon 6 resin and nylon 66 resin. It is specific.
すなわち熱変形温度の値が低下するということは、ナイ
ロン４６樹脂のもつ大きな特長の１つが失われるという
ことであり、その利用上の価値が大きく低下する。In other words, a decrease in the value of heat distortion temperature means that one of the major features of nylon 46 resin is lost, and its utility value is greatly reduced.

ロン４６樹脂に固有のものである。General polyamide resins such as nylon 66 resin have a lower melting point than nylon 46 resin and the decomposition point remains the same, so the temperature range in which extrusion and molding can be performed is sufficiently wide, and the degree of crystallinity is also lower than that of nylon 46 resin. It is also easy to plasticize, and the above-mentioned problems are unique to nylon 46 resin, which has a high melting point and high heat distortion temperature.

However, it has excellent extrusion and moldability, and the drop in heat distortion temperature is suppressed by incorporating nylon 6 resin, and not only the mechanical strength but also the melt flow characteristics of the composition are superior to nylon 46 resin. The present invention was achieved based on the discovery of a completely unexpected effect that is no different from the case of using only one substance.

ラツキが大きくなるので好ましくない。When using a nylon 46 resin with an intrinsic viscosity exceeding 1.90, the fluidity of the composition is poor, and the resulting molded product not only loses its glossy appearance but also has large variations in its mechanical and thermal properties. This is not desirable.

用上問題が生じてくる。The amount of the higher fatty acid or its derivative is 0.01 to 10 parts by weight. If the amount is less than 0.01 part by weight, the effect of suppressing the reduction in heat distortion temperature will not be sufficiently exhibited, and if it exceeds 10 parts by weight, not only will it not be possible to increase the effect by increasing the amount, but also decomposition will occur frequently due to lack of heat resistance. This causes practical problems such as a decrease in the melt viscosity of the polymer.

形温度低下が抑えられた（実施例１・２）。When nylon 46 resin alone is cross-extruded, a high set temperature is required to completely melt the resin, and the load at that time is extremely large (Comparative Example 1). nylon 4
When a small amount of nylon 6 resin is blended with nylon 46 resin, the load is significantly reduced even at a lower temperature setting than when using nylon 46 resin alone, making stable kneading and extrusion possible (Comparative Example 2)
・3・5. Examples 1, 2, and 3). This effect is nylon 6
Comparative Example 4) had a greater effect than when using 6 resins. However, when nylon 6 resin is blended with nylon 46 resin, the disadvantage is that the high heat distortion temperature value, which is one of the characteristics of nylon 46 resin, decreases (Comparative Examples 2 and 3).
). When higher fatty acids or derivatives thereof were blended into this system, the decrease in heat distortion temperature of nylon 46 resin caused by blending nylon 6 resin was suppressed (Examples 1 and 2).

When higher fatty acid or its derivative is blended with nylon 46 resin alone, the The effect of further increasing the heat distortion temperature did not occur (Comparative Example 3),
Higher fatty acids or derivatives thereof exhibited the above-mentioned effects only when nylon 46 resin and nylon 6 resin were combined. It was also found that even when higher fatty acids or their derivatives were blended with nylon 6 resin, which has a low heat distortion temperature, the value did not increase (Comparative Example 4).
