Title: METHOD FOR PRODUCING LOW CRYSTALLINITY CELLULOSE, AND RESIN COMPOSITION
Abstract:
The present invention pertains to a method for producing a cellulose-containing powder having a cellulose type-I crystallinity index of at least -20% and less than 50%, the method comprising a step in which 0.1-100 parts by mass of one or two or more additives selected from the group consisting of (A) a polymer compound having an acid anhydride, (B) a low molecular weight compound having an acid anhydride, and (C) a silane coupling agent is added to 100 parts by mass of a cellulose-containing raw material having a cellulose type-I crystallinity index of at least 10% and less than 100%, and the resultant mixture is subjected to dry grinding. The cellulose-containing powder obtained by the production method of the present invention can be suitably used for various industrial applications such as sundry goods, home appliance parts, automobile parts, and the like.
