The swelling and streching of celluose acetate films in aceton-water were investigated. (1) The effect of temperature and concentration on swelling is explained by a) lower swelling derived from solventation and b) higher swelling derived from relaxation of junction point of network. (2) Effective range of swelling in streching exists between 1.30 and 1.91. In this range, biref ringence increases linearly, its orientation is effective and stable, and junction points are formed. But, at higher (lower) swelling, they are ineffective owing to sliding of moleculor chains (insufficient relaxation). (3) Abrupt decrease of shrinkage at 200-300% of stretching and increase of strength, and maximum of elongation at break in this swelling range may be derived from same mechanism.
