RESIN COMPOSITION AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a molded article that has the satisfactory characteristics required as heat-resistant bottles with the stably improved crystallinity at the mouthpiece of the bottle. SOLUTION: The objective resin composition is produced by formulating (B) poly(tetramethylene naphthalenedicaboxylate) to (A) a poly(ethylene terephthalate) that is produced by the polycondensation reaction using a germanium compound as a catalyst and has an intrinsic viscosity of 0.70-0.90 in an amount of 1-100 ppm.
