Abstract: PURPOSE:To enable ester interchange reaction of a dicarboxylic acid dialkyl ester with an alkylene glycol in short time and high stability, by performing he reaction in a reaction system under a pressure higher than atmospheric pressure and discharging the alkylene glycol out of the system. CONSTITUTION:Dialkyl ester of 1,2-bis(chlorophenoxy)ethane-4,4'-dicarboxylic acid is subjected to ester interchange reaction with an alkylene glycol under a pressure higher than atmospheric pressure, preferably under 0.1-3kg/cm G pressure. After the completion of the reaction, the pressure of the reaction system is lowered preferably to G and remaining alkylene glycol is discharged from the system to obtain bis(beta-hydroxyalkyl)-1,2-bis (chlorophenoxy)ethane-4,4'-dica-rboxyl ate or its oligomer.

Abstract: PURPOSE:To obtain a film, which has high Young's modulus and is excellent in high-speed slitting, by a method wherein polyester containing specified components is biaxially oriented and heat-treated so as to set the density, the change of thickness and the friction coefficient of a resultant film at specified values respectively. CONSTITUTION:In a film consisting of polyester, the major component of which is carboxylic acid residue and ethylene glycol residue represented by a structural unit I, which contains at least one kind out of carboxylic acid residues represented by structural units II and III and the molar ratio of said residues of which satisfies the formula represented at the lowermost line, its density lies within the range of 1.44-1.50g/cm , the change of its thicknesses in width direction is 15% or less and its friction coefficient lies within the range of 0.5-4.0. Because the film, which has high Young's modulus and is excellent in slitting at high speed, the film can be thinned and consequently the miniaturization of magnetic tape and capacitor can be contrived.

Abstract: PURPOSE:To obtain the titled slurry which has good affinity with polymers and can be easily finely divided and in which the quantity of particles can be controlled, by dissolving a reaction mixture contg. a precipitate in ethylene glycol and heating the mixture to re-precipitate fine particles. CONSTITUTION:Terephthalic acid and/or its derivative such as dimethyl terephthalate, a Ca compd. such as calcium acetate monohydrate and ethylene glycol are reacted together in ethylene glycol at a temp. in the range of from 100 deg.C to the b.p. of ethylene glycol to form terephthalic acid and/or its derivative. The reaction mixture is diluted with ethylene glycol or cooled to 40 deg.C or below. Alternatively, the reaction mixture is diluted with ethylene glycol and cooled to 40 deg.C or below to dissolve a precipitate in the reaction mixture. While using a dispersion means, the temperature of the reaction mixture is elevated to re- precipitate fine particles, thus producing the titled slurry. A polyester contg. fine particles obtd. by adding the lubricant slurry is particularly suitable for use in producing a base film for magnetic tape, for which surface smoothness and slipperiness are required.

Abstract: PURPOSE:To obtain the titled polyester excellent in transparency and low in acetaldehyde content, by heat-treating a polyethylene terephthalate prepolymer having specifed properties, thereby enhancing its crystalinity and then subjecting the prepolymer to solid-phase polymerization. CONSTITUTION:In carrying out a polycondensation reaction subsequent to esterification of terephthalic acid with ethylene glycol, an antimony compound and/or a germanium compound are used as a catalyst. A polyethylene terephthalate prepolymer, intrinsic viscosity >=0.5, is prepared having a residual phosphorus content P (ppm), a residual antimony content Sb (ppm), a residual germanium content Ge (ppm) and a diethylene glycol component content DEG (wt. %) which satisfy the respective relationships. The purpose polyester is obtained by heat- treating the prepolymer to enhance its crystallinity to above 50% and Subjecting continuous solid-phase polymerization at a temperature of 190 deg.C- m.p. under a stream of inert gas.
