    • Provided herein is a cellulose nanofiber that can be easily combined with a compound having a reactive double-bond group and that can provide a molded article which contains only a small amount of an uncured material that acts as a plasticizer in a molded product, using a simple producing method that does not require any process involving solvent displacement or solvent removal. A high-strength resin composition or molded body prepared by using the cellulose nanofiber is also provided. In refining cellulose in the presence of a compound having a reactive double bond and a hydroxyl value of 200 KOHmg/g or more, the cellulose has a moisture content of 4 to 25 parts by mass with respect to 100 parts by mass of the amount of the cellulose converted on the assumption that the percentage moisture of the cellulose is 0%.
    • 本文提供的纤维素纳米纤维可以容易地与具有反应性双键基团的化合物组合,并且可以提供在模制产品中仅含少量作为增塑剂的未固化材料的模制品,其使用 简单的生产方法,不需要涉及溶剂置换或溶剂去除的任何工艺。 还提供了通过使用纤维素纳米纤维制备的高强度树脂组合物或成型体。 在具有反应性双键和羟基值为200KOHmg / g以上的化合物存在下,纤维素的纤维素相对于100质量份的水分含量为4〜25质量份 假设纤维素的水分百分比为0%,则纤维素被转化。
