RESIN COMPOSITION FOR BLOW-MOLDED HOLLOW ARTICLE, BLOW-MOLDED HOLLOW ARTICLE, AND PRODUCTION PROCESSES

Document Type and Number:

WIPO Patent Application WO/2011/148929

Kind Code:

A1

Abstract:

Provided are a resin composition for blow-molded hollow articles which has high industrial-scale productivity and has excellent moldability and drawdown resistance and a process for producing the resin composition, the process comprising melt-mixing 100 parts by mass of a polyarylene sulfide resin that contains terminal carboxy groups in an amount of 25-45 µmol/g, has a non-Newtonian index of 0.90-1.15, and has a melt viscosity as measured at 300ºC of 1,000-3,000 P with 5-30 parts by mass of an epoxidized polyolefin. Also provided are a blow-molded article that has excellent heat resistance, mechanical strength including impact resistance, and surface appearance and a process for producing the blow-molded article.
