The problem is solved by a method for producing a polyester, the method comprising: an esterification reaction step in which a diol component containing 1,4-butanediol and a dicarboxylic acid component are reacted with each other; a pelletization step in which a polyester obtained through the esterification reaction step is pelletized; and a contact treatment step in which polyester pellets obtained by the pelletization step are brought into contact with a contact treatment liquid. In the contact treatment step, the concentration of cyclic dimers in the contact treatment liquid, which is in contact with the polyester pellets, is 3,500 ppm by mass or less.

Abstract

A synthetic adsorbent, where a maximum value of a differential pore volume under a pressure condition of 0.5 to 30.0 psia is greater than 0.05 mL/g. A method of measuring the differential pore volume includes reducing a pressure in a sample container where the synthetic adsorbent that has been dried is placed to 10 Pa or less, mercury is degassed by reducing the pressure to 10 Pa or less, and the sample container is filled with the mercury at a pressure of 0.5 psia, measuring a mercury intrusion amount when the pressure in the sample container filled with the mercury is increased from 0.5 to 30.0 psia, and calculating the differential pore volume by dividing an amount of an increase in the mercury intrusion amount when a first-stage pressure calculated based on the mercury intrusion amount measured in the measuring is increased, by a measured amount of the synthetic adsorbent.

Abstract

The present invention provides an improvement relating to a method for producing a fiber-reinforced resin article at least partially having a structure comprising a bent or curved wall surface, such as a hollow structure part or a U-shaped cross-sectional structure part. A method for manufacturing a fiber-reinforced resin article according to the present invention has a molding step of heating, in a press metal mold, a prepreg preform together with a core comprising a wax material to obtain a cured product and a core removal step of removing the core from the cured product, where the core has an expansion part comprising a first wax material and a stamper part comprising a second wax material that is incompatible with the first wax material, the stamper part is disposed on a surface of the core, and a portion mirroring a shape of a surface of the stamper part is formed on a surface of the cured product.
