<p><P>PROBLEM TO BE SOLVED: To provide a polyethylene terephthalate resin composition capable of obtaining blow-molded containers with high heat resistance and transparency in high productivity, and to provide such a blow-molded container using the above resin composition. <P>SOLUTION: The polyethylene terephthalate resin composition comprises the components (A) and (B) described below, wherein the component (B) is contained at 0.1-10,000 ppb in the composition. The component (A) is a polyethylene terephthalate component consisting maily of recurring units derived from dicarboxylic acid(s) comprising terephthalic acid and/or its ester-forming derivative and diol(s) comprising ethylene glycol and/or its ester-forming derivative, wherein the proportion of diethylene glycol units is 0.5-2.0 wt.%. The component (B) is an ethylene-based polymer composition comprising (a) polyethylene and/or (b) an ethylene-(meth)acrylic acid copolymer, being greater than 45 in Shore D hardness. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
