ABSTRACT:
A plasticized cellulose acetate is described with a content of a modified cellulose acetate A comprising a grafted oligomer of a cyclic ester, in particular in the form of .epsilon.-caprolactone, which comprises additionally a plasticizing agent in the form of an oligomer B of a cyclic ester, and the terminal carboxyl group of the oligomer is esterified with an alcohol or an alcohol derivative having at least one free hydroxyl group, with a boiling point of at least approximately 120.degree. C. and a melting point of no more than approximately 180.degree. C. and the ratio of weight of component A to B is represented by the formula (I)
