The present invention relates to a biodegradable polyester resin, in which the first repeat unit comprising a first diol residue and an aromatic dicarboxylic acid residue and the second repeat unit comprising a second diol residue and an aliphatic dicarboxylic acid residue satisfy a ratio of the number of repeat units in a specific range, and the softness index of the resin satisfies a specific range, and to a process for preparing the same. Since the biodegradable polyester resin can provide a biodegradable polyester sheet or film that can be simultaneously enhanced in productivity, processability, and moldability and is excellent in tensile strength, tear strength, and friction coefficient and excellent in biodegradability and water degradability, it can be utilized in more diverse fields.

An object of the present disclosure is to provide a cellulose acetate film having excellent bending properties and high transparency. The subject cellulose acetate film contains cellulose acetate having a cellulose triacetate I crystal structure, the cellulose acetate film having a light transmittance of 70% or higher at 660 nm.

Disclosed herein is a degradable cellulose ester. The cellulose ester may be formed into tow for use in cigarette filters or into articles, such as molded articles. A basic material, an enzymatic material, or combinations thereof is included in the cellulose ester in order to degrade the cellulose ester.

Disclosed is a plasticized cellulose ester composition. The plasticized cellulose ester composition of the present invention includes at least one cellulose ester and a plasticizer system. The plasticizer system includes epoxidized bio-derived oil in an amount of from 2% to 32% by weight based on the total weight of the plasticizer system. Flooring articles with at least one layer formed from the composition are also described.
