Description of the Related Art By blending a polyolefin and a polyamide, a composition having the characteristics of the polyolefin (eg, light specific gravity, low cost, water resistance, etc.) and the characteristics of the polyamide (eg, heat resistance, rigidity, etc.) Attempts have been made for a long time, but polyolefins and polyamides are incompatible and simple mechanical blends have drawbacks such as difficulty in pulling strands during extrusion due to the ballast effect and poor surface condition. Can be seen.

There is an example in which compatibility is improved by addition.

物に対して多くなり十分な物理的特性が得られない。However, in these compositions, the modified polyolefin occupies the majority of the composition, the properties of the polyolefin and the polyamide are lost, and sufficient physical properties cannot be obtained. However, in order to obtain sufficient compatibility, it is desirable that all the added polyamides undergo a graft reaction with a polyolefin modified with an unsaturated carboxylic acid or a derivative thereof. That is, a polyolefin modified with an unsaturated carboxylic acid or a derivative thereof may be added so that the ratio of the amount of acid groups contained in the polyolefin to the amount of terminal amino groups contained in the polyamide is 1: 1. The amount of polyolefin added is too large for the composition to provide sufficient physical properties.

面においては、良好であるが、反応性が悪く添加量も多
くなってしまう。In general, a polyolefin modified with an unsaturated carboxylic acid or a derivative thereof has a lower molecular weight as the amount of acid groups added is increased. Such modified polyolefin having a large amount of acid group addition has a low molecular weight and thus has high graft reactivity, but is poor in terms of interfacial adhesion between the two phases of polyolefin and polyamide. On the contrary, if the molecular weight of the modified polyolefin is kept high, the amount of acid group addition will be low. Since such a modified polyolefin has a high molecular weight, it is good in terms of interfacial adhesion, but it has poor reactivity and a large amount is added.

The above object can be achieved by adding two types of polyolefins, one having a high molecular weight and the other having a low molecular weight, and at the same time partially improving or retaining general physical properties such as rigidity, hardness, heat resistance, surface gloss, and water absorption. At the same time, they found that the tensile elongation and impact resistance were significantly improved, and completed the present invention.

伸度、耐衝撃性を著しく向上せしめ得た点にある。The characteristic feature of the polyolefin composition of the present invention is that the compatibility of the polyolefin and the polyamide, that is, the dispersion of the polyamide is improved by using two kinds of modified polyolefins having different molecular weights in the blend of the polyolefin and the polyamide. Moreover, the interfacial adhesion between the two phases is also improved. This is because the effect of modifying the polyolefin by the polyamide can be sufficiently exhibited, and the tensile elongation and impact resistance of the composition can be remarkably improved.
