The conditions under which cellulose‐cellulose triacetate (CTA) and cellulose‐poly(acrylonitrile) (PAN) blends can be prepared from solution, are described in this paper. These two systems form transparent films when the blend contains less than 50% PAN or 60% CTA. Young's modulus, tensile strength, and elongation at rupture were measured for these blends. These values usually are between those of the corresponding homopolymers, except for the blend containing 10% polymer (PAN or CTA) which has a tensile strength value larger than that of cellulose. This result seems to indicate a certain level of compatibility for this blend. However, x‐ray measurements indicate the presence of two crystal structures for these systems, suggesting that compatibility does not exist at the molecular level, in the crystalline fraction of the samples.
