    摘要： A process for production of a polyester comprising units of ethylene terephthalate as the major repeating units by supplying terephthalic acid and ethylene glycol continuously or intermittently to bis(beta-hydroxyethyl) terephthalate or its oligomer so as to carry out esterification under a pressure of not more than about 1.0 kg/cm.sup.2, followed by polycondensation, which is characterized in that at least one magnesium compound is incorporated into the reaction system in an amount of about 30 to 400 ppm in terms of Mg to the polyester when the esterification rate in the step of esterification reaches about 20-80% and at least one phosphorus compound is incorporated into the reaction system in an amount as satisfying the following equation (I) at the stage after the esterification rate reaches not less than about 91% and before the termination of the initial condensation in the step of esterification:1.2.ltoreq.Mg/P.ltoreq.20 (I)wherein Mg/P is the atomic ratio of the magnesium atom to the phosphorus atom. The produced polyester shows a high electrostatic adherence.

    摘要： A process for preparing a polyamide type film which comprises melt-extruding a polyamide resin having a metal compound and a melt specific resistance of not more than 1.5.times.10.sup.5 .OMEGA.cm at 260.degree. C. in a form of a film, contacting the melt-extruded film closely with a revolving cooling drum through static electricity and taking up the film while cooling rapidly to solidify, which provides remarkable improved adhesion by static electricity. As a result, increasing the take-up rate of the revolving cooling drum does not cause trapping of air between the drum and the film so that a film having excellent uniformity in thickness and transparency can be produced.

    摘要： A polyester film having a coefficient of dynamic friction between the film and a metal at 80.degree. C. of not more than 0.45, a polyester film composed of a polyester comprising an ethylene terephthalate unit in a proportion of 70% or more by mole, the polyester film comprising a cyclic ethylene terephthalate trimer in a proportion of 0.7% or less by weight, laminated metal sheets and metal containers manufactured from said laminated metal sheet. According to the present invention, the polyester film shows superior sliding property and superior scratch resistance during can production, as well as the elution of oligomer from the film can be suppressed, so that when the film is used for metal containers for food, the change in taste and smell of the food contained therein and degraded appearance of the surface of the film caused by the deposition of oligomer are avoided.
