    摘要： Provided is a foam sheet including a composition including polylactic acid. The polylactic acid includes, as monomer units, D-lactic acid and L-lactic acid, and an amount of the D-lactic acid or the L-lactic acid in the polylactic acid is 90 mol % or greater but less than 98 mol %. An amount of the polylactic acid is 97% by mass or greater relative to a total amount of organic matter in the foam sheet. When the foam sheet is cut into a square test piece, and the test piece is heated and stored for 90 minutes in a hot air circulation dryer a temperature of which is maintained at 90° C.±2° C., a change rate of an area of the test piece before and after the heat storage is within ±15%. An average thickness of the foam sheet is 0.5 mm or greater.

    摘要： A toner comprising a binder resin is provided. When the toner is observed with an atomic force microscope in tapping mode to obtain a phase image and the phase image is binarized with an intermediate value between maximum and minimum phase difference values in the phase image to obtain a binarized image, the binarized image consists of first phase-contrast portions having a large phase difference and second phase-contrast portions having a small phase difference, where the first phase-contrast portions are dispersed in the second phase-contrast portions and a dispersion diameter of the first phase-contrast portions is in a range of from 150 to 500 nm. The toner has at least two glass transition temperatures (Tg) in respective ranges of from 40° C. to 65° C. and from −30° C. to 20° C., determined from a DSC curve obtained at a first temperature rise in a differential scanning calorimetric measurement by a midpoint method.

    摘要： A method for producing a polymer, including: (i) bringing a compressive fluid and raw materials containing a ring-opening polymerizable monomer into contact with each other at a mixing ratio represented by the following formula, to thereby allow the ring-opening polymerizable monomer to carry out ring-opening polymerization in the presence of a metal catalyst: 1{Mass of the raw materials/(Mass of the raw materials+Mass of the compressive fluid)}0.5.
