The disentanglement adjuvant for hydrophobization cellulosic fibers， the manufacturing method of a resin composition using the same， and a molded object

This fibrillation aid is for fibrillating a hydrophobized cellulose-based fiber assembly in which the hydrogen atom of some of the hydroxyl groups of the cellulose-based fiber is substituted with an acyl group represented by general formula (A) Ra-CO- (in the formula， Ra indicates a C1-4 alkyl group， or a phenyl group that may have an electron-releasing substituent)， or with an optionally substituted alkyl group represented by general formula (B) Rb- (in the formula， Rb indicates a C1-4 alkyl group， a 2-hydroxyethyl group， a 2-hydroxypropyl group， a 2-cyanoethyl group， or an allyl group). The principal constituent of the fibrillation aid is an amide compound represented by general formula (1) R1-CO-N(R2)-R3 (In the formula: R1 and R3， which may be the same or different， each indicate a hydrogen atom or a C1-4 alkyl group， or R1 and R3 together indicate a C3-11 alkylene group; and R2 indicates a hydrogen atom， a C1-3 alkyl group， or a C2-4 acyl group.).
