    摘要: This invention relates to a blend comprising(a) about 2% to about 98% by weight of at least one ester of cellulose comprising an alkanoyl chain having from about 1 to about 10 carbon atoms, and having at a D.S. of about 2.3 to about 3.0, and an inherent viscosity of about 0.2 to about 3.0 deciliters/gram as measured at a temperature of 25.degree. C. for a 0.5 g sample in 100 ml of a 60/40 parts by weight solution of phenol/tetrachloroethane, and(b) about 98% to about 2% by weight of at least one ester of cellulose comprising an alkanoyl chain having from about 1 to about 10 carbon atoms, and having a D.S. of about 1.5 to about 2.2, and an inherent viscosity of about 0.2 to about 3.0 deciliters/gram as measured at a temperature of 25.degree. C. for a 0.5 g sample in 100 ml of a 60/40 parts by weight solution of phenol/tetrachloroethane, said percentages being based on the weight of component (a) plus component (b).
