Abstract: Provided is a process for producing a polyester composition, comprising carrying out an esterification reaction of dicarboxylic acid component with diol component, and then carrying out a polycondensation reaction, wherein the diol component is added twice or more during the time from the completion of the esterification reaction until the start of the polycondensation reaction, and alkali metal phosphate is added with the amount of COOH terminal groups of an esterification reactant being not more than 150 eq/ton. Provided is a process for producing a polyester composition suitable for use in a film with excellent hydrolysis resistance.

Abstract: A method and apparatus for producing a thermoplastic resin sheet, in which a melt-extruded running thermoplastic resin sheet is brought into contact with a rotating cooling body, to be cooled and solidified, for producing a cast sheet, comprising the use of an electrifying body rotating in contact with the sheet, with the sheet kept running between the cooling body and the electrifying body. The charges given from the electrifying body rotating in contact with the sheet to the sheet keep the sheet in contact with the surface of the cooling body.

Abstract: DISCLOSED IS A METHOD FOR OBTAINING A POLYESTER, WHEREIN A DICARBOXYLIC ACID OR AN ESTER-FORMING DERIVATIVE THEREOF AND A DIOL OR AN ESTER-FORMING DERIVATIVE THEREOF ARE ESTERIFIED OR TRANSESTERIFIED, AND THEN THE RESULTING PRODUCT IS POLYCONDENSED IN THE PRESENCE OF A TITANIUM POLYCONDENSATION CATALYST. IN THIS METHOD, GENERATION OF AN EXTRANEOUS MATERIAL CAUSED BY THE CATALYST AND MOLD CONTAMINATION DURING MOLDING CAN BE REDUCED BY ADDING A PHOSPHORUS COMPOUND HAVING A SPECIFIC STRUCTURE, AND THUS THERE CAN BE OBTAINED A POLYESTER WHICH IS REMARKABLY IMPROVED IN THERMAL STABILITY AND A COLOR TONE OF THE POLYMER WHEN COMPARED WITH THE CONVENTIONAL POLYESTERS.
