摘要： The present invention provides a masterbatch method for producing a polyester resin and articles thereof; comprising reacting following materials uniformly at a temperature equal to or greater than the melting point of a polyester, the materials comprising: (1) 100 parts by weight of saturated straight-chain polyester A; (2) 1 to 10 parts by weight of binder masterbatch D comprising: a mixture containing a compound having two epoxy groups and a compound having an average number of epoxy groups of 2.1 or more; (3) 0.25 to 10 parts by weight of catalyst masterbatch G comprising: a metal carboxylate, whereby the melt viscosity of the polyester increases so that the melt flow rate (MFR) becomes 50 g/10 min or less, and the degree of swelling of the polyester increases to between 5% and 200%, thus resulting in a high-quality resin having excellent mechanical properties. The resin can be advantageously used for films, sheets, foamed materials, pipes, cushioning, heat insulators, packing materials, and so forth.

A foamed article useful as cushioning material, heat insulating material, packaging material, food container, and dividers can be produced by increasing the molecular weight, melt viscosity, and swell (degree of swelling) of PET-based polyesters that have relatively low molecular weight and are brittle, especially recovered polyester, that is used as a prepolymer.
