    • 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.
    • 一种通过连续或间歇地向双(β-羟乙基)对苯二甲酸酯或其低聚物供应对苯二甲酸和乙二醇作为主要重复单元的聚对苯二甲酸乙二醇酯单元的生产方法,以在不超过一个压力下进行酯化 约1.0kg / cm 2,然后进行缩聚,其特征在于当步骤中的酯化速率在聚酯中时,至少一种镁化合物以约30-400ppm的量掺入反应体系中 的酯化达到约20-80%,并且在酯化速率达到不低于约91%之后且在终止之前的阶段,至少一种磷化合物以满足以下等式(I)的量引入反应体系中 在酯化步骤中的初始缩合:1.2 Mg / P 20(I)其中Mg / P是镁原子与磷酸根的原子比 原子 所生产的聚酯显示出高的静电附着力。

    • A thermoplastic resin film laminate which comprises a thermoplastic resin film, particularly, a polyester film and a layer of a polyester resin composition provided on at least one surface of the film, said composition comprising(A) a water insoluble polyester copolymer composed of a mixed dicarboxylic acid component containing a dicarboxylic acid having metal sulfonate group in an amount of 0.5 to 15 mol % based on all the dicarboxylic acid component and a glycol component; and(B) inert particles; the weight ratio of (A)/(B)=100,000/0.5-3,000. Optionally, the composition can contain one or more ingredients selected from the group consisting of a water soluble silicone, a polyfunctional reactive compound, a polyethylene glycol and its derivative and an antistatic agent. The thermoplastic resin film laminate is preferably produced by so-called in-line coating.
