Claims
- 1. A liquid keeping container comprising a molded product of a material comprising a resin composition,wherein the resin composition comprises a syndiotactic polystyrene resin and a polypropylene resin and has a compatibilized structure of the syndiotactic polystyrene resin phase and the polypropylene resin phase, the proportion of these phases being 90-10/10-90 (weight ratio); and wherein the container is a part of an automobile anti-freeze system.
- 2. The liquid keeping container according to a claim 1, wherein the polypropylene resin is a continuous phase and the sydniotactic polystyrene resin is a disperse phase in the compatibilized structure.
- 3. The liquid keeping container according to claim 1, wherein the polypropylene resin is a disperse phase and the syndiotactic polystyrene resin is a continuous phase in the compatibilized structure.
- 4. The liquid keeping container according to claim 1, wherein the resin composition further comprises a thermoplastic elastomer in an amount of 1-200 parts by weight based on 100 parts by weight of the syndiotactic polystyrene resin.
- 5. The liquid keeping container according to claim 4, wherein the thermoplastic elastomer is a styrene thermoplastic elastomer or an olefin thermoplastic elastomer, or a combination of a styrene thermoplastic elastomer and an olefin thermoplastic elastomer.
- 6. The liquid keeping container according to claim 1, wherein 0.1-100% by weight of the polypropylene resin is modified with maleic anhydride.
- 7. The liquid keeping container according to claim 1, wherein the resin composition further comprises a polyphenylene ether resin in an amount of 1-200 parts by weight based on 100 parts by weight of the syndiotactic polystyrene resin.
- 8. The liquid keeping container according to claim 7, wherein 0.1-100 parts by weight of the polyphenylene ether is modified with maleic anhydride.
- 9. The liquid keeping container according to claim 1, wherein the resin compostion comprises:(A) 10-90% by weight of the syndiotactic polystyrene resin, (B) 10-90% bty weight of the polypropylene resin, (C) 1-200 parts by weight of a themoplastic elastomer base on 100 parts by weight of the above component (A), and (D) 1-200 parts by weight of a polyphenylene ether resin based on 100 parts by weight of the component (A).
- 10. The liquid keeping container according to claim 1, further comprising an inorganic filter.
- 11. The liquid keeping container according to claim 10, wherein the inorganic filter comprises a glass filter.
- 12. The liquid keeping container according to claim 4, wherein 0.1-100% by weight of the themoplastic elastomer is modified with maleic anyhydride.
- 13. The liquid keeping container according to claim 9, wherein 0.1-100% by weight of the themoplastic elastomer is modified with maleic anhydride.
- 14. The liquid keeping container according to claim 9, wherein the resin compostion further comprises 10-200 parts by weight of an inorganic filler based on 100 parts by weight of (A), (B), (C) and (D).
- 15. The liquid keeping container according to claim 14, wherein the inorganic filler comprises a glass fiber.
