The present application discloses a method of reducing acid and ester degradation products during calendering of cellulose ester containing plasticiser using certain additives such as primary antioxidants and metal alkanoate. The compositions comprising the additives exhibit significant reductions in acids and ester degradation products as compared to compositions not comprising the additives.

A method for producing a cellulose derivative, including reacting a mixed acid anhydride having two particular types of acyl groups with cellulose in the presence of a base catalyst in an organic solvent having an electron pair-donating property to form a cellulose derivative with the two types of acyl groups derived from the mixed acid anhydride, the acyl groups being introduced at hydroxy groups in the cellulose.

A polymer composition containing the reaction product of a cellulose ester polymer and a reactive flow aid. The reactive flow aid can be a polyester oligomer and can be chemically associated with the cellulose ester polymer by being melt blended with the polymer in the presence of a catalyst, such as an acid species. The polymer composition of the present disclosure has excellent flow properties and is well suited for producing molded articles, such as injection molded articles.

Provided is a resin composition containing: a thermoplastic resin having a polar group; and a heterocyclic compound containing two or more heteroatoms, wherein the resin composition exhibits a different behavior in elastic strength with a glass transition temperature as a boundary.

This invention relates to cellulose ester compositions cable of being calendered. The invention also relates to calendered films or sheets comprising the cellulose ester compositions and processes for calendering the cellulose compositions.
