Abstract:
PROBLEM TO BE SOLVED: To provide a method which is more conveniently used to produce non-solid products (e.g., polyester coatings) initially before employing pelletized solid polyester resins in consideration of: shortening the cycle time of polyester production; obtaining products in a syrup form; and containing a polymer and a nonreactive carrier.SOLUTION: An oligomer is converted into a polymer by polycondensation at high temperature under high pressure in a nonreactive carrier capable of forming an azeotrope with water, and medium and high molecular weight polyester polymers are produced in a syrup form from an ester oligomer. The oligomerization and polycondensation reactions are monitored using a non-viscometric measurement method.

PROBLEM TO BE SOLVED: To provide a can containing no movable BPA nor an aromatic glycidyl ether compound.SOLUTION: In the can containing a body and a cover, at least one of the body and the cover is composed of aluminum, and at least one major surface of them is coated with a coating composition. The coating composition contains two or more polyester resin compounds. Each polyester resin is formed by making one or more kinds of polyacid molecules react with one or more kinds of polyol molecules. The compound contains 60 to 90 wt.% of a polyester resin (i) having a glass transition temperature of 50°C, and a cross-linking agent. Furthermore, the coating composition contains 2 to 10 wt.% of an acrylate copolymer based on the solid content. The coating composition does not substantially contain the movable bisphenol A and the aromatic glycidyl ether compound.
Abstract:
PROBLEM TO BE SOLVED: To provide a multilayer or monolayer plastic container having a barrier layer prepared by blending (i) a polyester resin, preferably an aromatic polyester resin such as a polyethylene terephthalate, (ii) a polyamide material, preferably an aromatic polyamide material, and (iii) an oxygen scavenging material, preferably a transition metal, and to provide a method of manufacturing the same.SOLUTION: In the preparation of the barrier layer, a preform first is prepared by an injection molding process, wherein a preblend containing a diluent polyester, polyamide material and the oxygen scavenging material is added to a base polyester during the injection molding process. The preform is expanded to form a container.
