摘要： PROBLEM TO BE SOLVED: To provide a polyester giving a film very suitable for electrical insulation which contains a cyclic trimer in a very small amount enough to keep low the amount of the cyclic trimer extracted from the film by a refrigerant in case that the film is brought into contact with the refrigerant when the film is employed for electrical insulation for an enclosed motor for a refrigerator thereby preventing troubles caused by deposition on various parts of the refrigerator of the trimer resulting in clogging, and is excellent in hydrolysis resistance, heat resistance and mechanical characteristics enough to further lengthen the life of the motor for a refrigerator. SOLUTION: The polyester composition comprises at least 90 mole% of an ethylene terephthalate unit and contains at least one polymerization catalyst metal compound selected among antimony compounds, germanium compounds and titanium compounds, where the amount of the polymerization catalyst metal compound in terms of the metal is at least 0.2 mole/ton and at most 1 mole/ton based on the polyester and the content of an ethylene terephthalate cyclic trimer is less than 0.4 wt.% based on the polyester.

摘要： PROBLEM TO BE SOLVED: To form a magnetic tape having a good high-temp. storage characteristic by providing the one side surface A of a polyester film with a ferromagnetic metallic thin-film layer, providing the one side surface B with a back-coating layer and incorporating wax and/or soap at a specific weight% range into a film forming the one side surface B thereof. SOLUTION: The one side surface A of the polyester film is provided with the ferromagnetic metallic thin-film and the one side surface B is provided with a back-coating layer. The polyester film is so composed as to contain the wax and/or soap in the range of 0.05 to 1.0wt.% in the film forming the one side surface B to be provided with the back-coating layer. If the wax or the soap is below 0.05wt.%, the oligomer of polyester is liable to be precipitated from the inside of the polyester film by the residual solvent in the back-coating layer and such ratio is undesirable. If the wax or the soap is included therein at a ratio higher than 1.0wt.%, the surface B of the polyester film becomes sticky and the strength of the adhesion of the back-coating layer degrades and such ratio is undesirable.

摘要： PROBLEM TO BE SOLVED: To form a magnetic tape having a good storage characteristic at a high temp. by incorporating wax and/or soap at a specific weight% range into a film forming the one side surface A of a polyester film. SOLUTION: The one side surface A of the polyester film consists of a film tightly adhered onto the polyester film and the particulates existing in the film and/or on the surface of the film. Such one side surface A of the polyester film is provided with a ferromagnetic metallic thin-film layer thereon. The polyester film is so composed as to contain the wax and/or soap in the range of 0.05 to 1.0wt.% in the film forming the one side surface A of the polyester film. Further, the SRa value of the one side surface A is preferably 2 to 5nm and the SRz value thereof 10 to 50n. If the grain size of the wax and soap is >=0.15μm, the surface roughness of the one side surface A of the polyester film increases and the electromagnetic conversion characteristics of the magnetic tape degrade.

摘要： PROBLEM TO BE SOLVED: To obtain a laminated film which has an effective protection for flavor, and outstanding heat resistance and shock resistance by arranging a polyester layer and a polyester layer comprising a polyester composition which contains a polyester plasticizer. SOLUTION: Polyester constituting a polyester layer (A) and a polyester composition constituting a polyester layer (B) are separately coated in advance and after the formation of a film, this film is laminated as one manufacturing method. Another method is to melt the polyester and the polyester composition separately and coextrude these molten materials from a die to manufacture the film. The polyester constituting the polyester layer (A) or the polyester layer (B) may be of whatever type than can be molded into the film. Especially, polyethylene terephthalate and polyethylene-2,6-naphthalene dicarboxylate are preferable from a viewpoint of heat resistance, shock resistance and protection for flavor. The polyester used for the polyester layer (B) contains a polyester plasticizer.

摘要： PROBLEM TO BE SOLVED: To obtain a polyester film excellent in flame retardancy, heat resistance, and hydrolysis resistance. SOLUTION: The composition contains structural units (a) represented by the formula in an amount of 0.5-18mol% based on the dicarboxylic acid units. When the composition is boiled in water at 120 deg.C for 50min, the resultant increase in the amount of terminal carboxyl groups satisfies the relationship ΔCOOH is a monovalent group consisting of carbon, hydrogen, oxygen, and nitrogen and R2 and R3 each is a divalent group consisting of these elements. The composition is usable as a film required to have flame retardancy and heat resistance. It is especially useful as various insulating films in printed circuit boards and for insulating pressure-sensitive tapes.

摘要： PURPOSE: To obtain the subject composition free from the crystallization of a polyester oligomer onto the surface of a film and useful for producing the film excellent in running properties by compounding an aromatic polyester with a specific sulfonic acid lithium salt. CONSTITUTION: This composition is obtained by compounding an aromatic polyester composed mainly of (A) an aromatic dicarboxylic acid and (B) an alkylene glycol with (C) 0.1-10wt.% of a lithium salt of a sulfonic acid of the formula RXSO3 Li (R is a 5-30C normal alkyl; X is an aromatic group). Further, the composition is preferably compounded with (D) particles insoluble in the polyester, having an average particle diameter of 0.01-2μm and substantially spherical (e.g. colloidal silica or spherical alumina) in an amount of 0.1-10.0wt.% based on the polyester. A film, which has polyester oligomers crystallized on its surface, having diameters of >=0.2μm, of after 2-hr aging at 120 deg.C, can be obtained by using the composition.
