FIELD: chemistry.
SUBSTANCE: invention relates to a composition of acetylcellulose for thermoforming with excellent capability of decomposition by microorganisms and excellent thermoformability. The composition of acetylcellulose for thermoforming contains a plasticizer based on glycerin ester in the amount of 5 wt.pt. or more and 40 wt.pt. or less per 100 wt.pt. of the total amount of acetylcellulose and plasticizer based on glycerol ester, and acetylcellulose has an acetyl substitution degree of 1.4 or more and 2.0 or less, a composite distribution index (CDI) of 4.0 or less, and a total sulfur content of 15 mg/kg or more and less than 150 mg/kg.
EFFECT: obtaining an acetylcellulose composition for thermoforming.
