Provided is a polymer material containing at least one kind of a cellulose derivative having (a) an organosilyl group (the organosilyl group having a first aliphatic group, an unsaturated aliphatic group, or an aromatic group), and (b) an acyl group or a second aliphatic group.

An injection molding composition is capable of being injection-molded easily at a temperature lower than that of a conventional composition, and an injection molded product has improved strength. More specifically, an injection molding composition containing HPMCAS has a hydroxypropoxy molar substitution of 0.40 or more. In addition, a method produces an injection molded product including a step of injecting into a mold the injection molding composition at from 50 to 250 C.

A process for preparing an esterified cellulose ether comprises the step of esterifying a cellulose ether with (i) an aliphatic monocarboxylic acid anhydride or (ii) a dicarboxylic acid anhydride or (iii) a combination of an aliphatic monocarboxylic acid anhydride and a dicarboxylic acid anhydride in the presence of acetic acid. The esterification reaction is conducted in the presence of an alkali metal diacetate as a reaction catalyst.
