MEDICAL PACKAGING CONTAINER
First Claim
1. A medical packaging container comprising a polyester resin (A1) comprising diol units and dicarboxylic units,the diol units comprising at least one diol unit in an amount of 1 to 30 mol % selected from diol units having a bridged alicyclic skeleton derived from a compound represented by formula (1), formula (2), or formula (3),the dicarboxylic acid units comprising dicarboxylic acid units having a naphthalene skeleton in an amount of 70 mol % or more.

22. A manufacturing method of a polyester resin, comprising the steps of:
-
producing an oligomer by transesterification of a dicarboxylic acid diester component comprising naphthalenedicarboxylic acid diester and at least one selected from the compounds represented by formula (1), formula (2), and formula (3), and a diol component comprising ethylene glycol in the presence of a manganese compound; and polycondensing the oligomer in the presence of an antimony compound; wherein a phosphorus compound is used as a thermal stabilizer, and wherein the polyester resin has a manganese atom content of 40 to 200 ppm and an antimony atom content of 50 to 200 ppm, with a ratio (M/P) of the total content (M) (ppm) of manganese atoms and antimony atoms to the phosphorus atom content (P) (ppm) of 1.5 to 4.0. - View Dependent Claims (23, 24, 25)
