<p><P>PROBLEM TO BE SOLVED: To provide a resin composition for a container to store sulfuric acid, which has excellent discoloring resistance, cleanliness to sulfuric acid, chemical resistance and excellent characteristics for blow molding, and also to provide a container made from the same. <P>SOLUTION: The polyethylene resin for a container to store sulfuric acid comprises a high density polyethylene having: (a) a melt flow rate (MFR) of 0.02-3 g/10 minutes at 190°C under the lord of 2.16 kg; (b) a flow ratio (FR=HLMFR/MFR) of 40-70, (wherein, HLMFR is a melt flow rate under the lord of 21.6 kg at 190°C; and MFR is a melt flow rate under the lord of 2.16 kg at 190°C); (c) the number of double bonds of at most 0.5 per 1,000 carbon atoms; (d) an amount of a chloride residue of at most 10 ppm. No additive is included in the above resin. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
