れる。(Conventional technology) Polyolefins have excellent moldability, toughness, water resistance, organic solvent resistance, chemical resistance, etc., and are low in specific gravity and inexpensive, so they have been widely used in various molded products, films, sheets, etc. However, since the heat resistance is not very high, it is desirable to improve this in order to develop new uses.

For the purpose of improving molding processability, impact strength, etc., it is blended with styrene resin and used, but its range of use is limited due to the drawback of solvent resistance.For example, it is used in gasoline containers, etc. Not suitable for fields that require resistance to oily solvents.

るが、なお実用上は満足し難い。Various blend compositions have been proposed to combine the advantages and compensate for the disadvantages of polyolefins and polyphenylene ethers. ), but it cannot necessarily satisfy the relatively high mechanical strength level required in the industrial field, and the purpose is to further improve the compatibility of polyolefin and polyphenylene ether resin to improve mechanical strength. For example, a composition elJ (Japanese Unexamined Patent Application Publication No. 1983-1973) comprising a block copolymer of styrene and butadiene or a hydrogenated product thereof is

Because it consists of a combination of polyolefins, the organic solvent resistance of polyolefins cannot be sufficiently exhibited.Also, polyphenylene ether resin is blended with multiple polyolefins exceeding 20% by weight, and an alkenyl aromatic compound and a conjugated diene are added as compatibilizers.

度と高いレベルの衝撃強度の両立は困難であった。On the other hand, as the uses of plastics have expanded in recent years, in addition to the above characteristics, performance at a level never seen before has become required.For example, coating to improve design, large-scale molding The product has dimensional stability at high temperatures, etc.
For the former, examples of technological development to address this issue include surface modification through plasma treatment, etc. Also, on the other hand,
Regarding the latter, conventionally, when painted plastic molded products are used in high-temperature environments, the degree of thermal expansion between the paint and the underlying plastic is different, resulting in peeling of the paint film and fine cracks on the painted surface, resulting in poor appearance. There are often cases where the design deteriorates, and when large plastic molded products are used in conjunction with molded products made of other materials, such as wood or metal, the dimensions may deteriorate due to the different degrees of thermal expansion in high-temperature environments. The current situation is that there are many cases where problems such as discrepancies and poor meshing occur. Therefore, it is desired to improve the dimensional stability of plastics at high temperatures and to establish a technology for controlling the degree of expansion, that is, the coefficient of linear expansion. To deal with this, various methods are generally considered, such as adding inorganic fillers, but at the same time, the molded product tends to become brittle, the impact strength level decreases, and its uses are usually severely limited. Therefore, it has been difficult to achieve both dimensional accuracy at high temperatures and a high level of impact strength.

だし、本発明を完成した。(Means for Solving the Problem) The present inventors have developed various polyolefin and polyphenylene ether resins in order to compensate for and improve the deficiencies in dimensional stability and mechanical properties of conventional polyolefin-polyphenylene ether blends. As a result of examining various compounding materials and inorganic fillers, we found a polymer that has both an alkenyl aromatic compound polymerization chain and an aliphatic hydrocarbon chain in the same molecule, and a talc (main component:
It was discovered that an excellent balance of mechanical strength, centering on dimensional stability and impact strength, can be obtained in high-temperature environments by blending hydrated magnesium silicate (hydrous magnesium silicate). It has been found that a composition obtained by kneading a previously melt-kneaded composition and the remaining components, in which the blending ratio of each component is substantially the same as above, is preferable because it exhibits much higher impact strength.
