Title:
CELLULOSE ACETATE AND CELLULOSE ACETATE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/085119
Kind Code:
A1
Abstract:
In this cellulose acetate, the total degree of acetyl substitution is from 1.75 to 2.55 and the degree of 2-position acetyl substitution and/or 3-position acetyl substitution is 0.7 or less. This cellulose acetate composition includes this cellulose acetate and additives. The additives are one or more selected from the group consisting of (a) substances a 1 wt% aqueous solution of which at 20°C has a pH of 8 or higher, (b) substances 2 wt% or more of which dissolves in 20°C water, and (c) substances that are biodegradable in seawater.
