Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polar group-containing olefin copolymer and a thermoplastic resin composition containing the copolymer, and more particularly, to an adhesive property with a metal or a polar resin,
The present invention relates to a polar group-containing olefin copolymer having excellent flexibility and a thermoplastic resin composition containing the copolymer.

[0002]

BACKGROUND OF THE INVENTION Generally, polyolefins are extruded because of their excellent moldability, heat resistance, mechanical properties, hygiene compatibility, water vapor permeability, etc., and good appearance of molded products. Widely used for molded products, hollow molded products, injection molded products, etc. On the other hand, engineering plastics such as nylon are used for electronic and electric parts because of their excellent heat resistance and strength. Engineering plastics such as nylon
Since the impact resistance is generally low, it is necessary to improve the impact resistance by blending an olefin copolymer or the like. However, polyolefins do not contain a polar group in the molecule and have low compatibility with polar resins. Therefore, methods for improving compatibility with polar resins by grafting a polar monomer have been widely used.

[0003] However, in this method, intermolecular cross-linking between polyolefins and breaking of molecular chains occur in parallel with the graft reaction, so that viscosity matching between the graft polymer and the polar resin is difficult, and there are cases where compatibility is not sufficient. there were. In addition, the appearance of the molded product was sometimes deteriorated due to the gel component generated by intermolecular cross-linking, the eyes generated by cutting molecular chains (foreign matter adhering to the lip of the die), and the like.

Further, Japanese Patent Application Laid-Open Nos. 1-259012, 1-259012, 2-51510, 2-51511 and 3-1774 are disclosed.
No. 03 describes a method of copolymerizing an α-olefin and a polar group-containing monomer using a Ti catalyst or a V catalyst. According to this method, cross-linking between molecules and breaking of molecular chains as described above are unlikely to occur, but when these polymerization catalysts are used, the obtained copolymer has a wide molecular weight distribution and an inversion content. In some cases, the molecular structure is non-uniform, for example, the number of the polar groups is large. Therefore, the orientation of the polar group at the interface with the polar substance is not sufficient, and the adhesiveness and compatibility with the polar substance are sometimes insufficient. When used as a composition, effects such as adhesiveness and compatibility may not be exhibited unless a large amount of the graft copolymer is added.

[0005] The present inventors have conducted studies in view of the above problems, and as a result, have found that a copolymer having a specific molecular structure and a composition containing the same have excellent compatibility with polar resins. Was completed.

[0006]

An object of the present invention is to provide a polar group-containing olefin copolymer excellent in adhesion, compatibility, flexibility and the like to a metal or a polar resin and a thermoplastic resin composition containing the copolymer. It is intended to be.

Example 5 In Example 4, ethylene was introduced in the same manner as in Example 4 except that propylene was introduced at an initial partial pressure of 3 kg / cm 2 instead of 1-butene, and polymerization was carried out at a polymerization temperature of 80 ° C. without adding hydrogen. And propylene and a polar group-containing monomer were polymerized. Table 2 shows the physical properties of the obtained polar group-containing olefin copolymer.

20% by weight of the polar group-containing olefin copolymer obtained as described above was mixed with nylon 6 (relative viscosity:
2.35 dl / g) at 80% by weight.
A thermoplastic resin composition was prepared by melt-kneading at 250 ° C. with a twin-screw extruder, and an impact resistance test and a tensile test were performed on the thermoplastic composition as described above. Table 3 shows the results.
