Title:
MOLDED BODY AND METHOD FOR PRODUCING CELLULOSE-NANOFIBER-CONTAINING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/049893
Kind Code:
A1
Abstract:
In the present invention, by means of a simple production method that absolutely does not require a solvent replacement step or a desolventizing step, provided are: cellulose nanofibers that are easily combined with compounds having a reactive double-bond group, function as a plasticizer in a molded body, and involve a low amount of uncured matter; and a high-strength resin composition and molded body that use the cellulose nanofibers. When refining cellulose in the presence of a compound having a reactive double-bond group and a hydroxyl value of at least 200 KOHmg/g, the amount of water with respect to 100 parts by mass of cellulose when the moisture content of the cellulose has been converted to 0% is 4-25 parts by mass.
