Document Type and Number:
WIPO Patent Application WO/2011/132745
Kind Code:
A1
Abstract:
Disclosed is a cellulose derivative that is suitable for molding processes and has excellent thermal plasticity and strength. Specifically disclosed is a cellulose derivative wherein hydrogen atoms of hydroxyl groups contained in the cellulose have at least one group substituted by (A)) and at least one group substituted by (B)), and the total molar degree of substitution for the -CnH2n-O- groups contained in the groups substituted by (A)) is 0.5 - 3.0. The number average molecular weight is 150,000 or greater.
(A)) Group containing the structure represented by general formula (1)
(B)) Acyl group: -CO-RB (RB represents a C1-3 hydrocarbon group.)
(In general formula (1), n represents 2 or 3, and RA represents a C1-3 hydrocarbon.)
