Abstract: PROBLEM TO BE SOLVED: To obtain a cellulose derivative resin composition improved in flexibility, non-volatility, and bleed-out resistance by mixing a vinyl (co)polymer having amido bonds as side chains with a cellulose derivative. SOLUTION: An amido-containing vinyl monomer (1-100 mol%, particularly, 2-100 mol%) is (co)polymerized with, optionally, an arbitrary copolymerizable vinyl monomer in the presence of a radical polymerization initiator to obtain a plasticizer comprising a vinyl (co)polymer (except a polyvinylpyrrolidone, polyacryloylmorpholine, or an N-vinylpyrrolidone/vinyl acetate copolymer) having amide bonds as side chains and having a number-average molecular weight of 1,000-500,000, particularly, 5,000-200,000. A cellulose derivative resin composition is obtained by kneading 2-98 wt.% above plasticizer and at least one cellulose derivative having a degree of acetylation of at least 52% and selected from among cellulose acetate, cellulose acetate propionate, and cellulose acetate butyrate.

Abstract: PROBLEM TO BE SOLVED: To provide a new separating agent for an optical isomer which has a high capacity of identifying asymmetry of a compound to be analyzed and aliquoted.
SOLUTION: In a polysaccharide derivative, each hydrogen atom of a hydroxyl group of a polysaccharide having an amino group or of the amino group is replaced with a functional group for reacting to the hydroxyl group or the amino group. The separating agent for the optical isomer contains the polysaccharide derivative having the average introduction number of the functional group of ≥3.0 in each monosaccharide unit.
