6. ABSTRACT A shape memory film formed from a shape memory trans- parent polymer, said shape memory film being capable of remembering a basic shape such as plane configuration and dead folds, taking on a second shape when the basic shape is modified (by changing the plane configuration and adding dead folds, twists, three-dimensional configura- tions, etc.) at a temperature higher than the glass trans- ition point of the polymer and lower than the molding tem- perature of the polymer, and having the second shape set when cooled to a temperature lower than the glass trans- ition point while being kept in the second shape; and a method of using said shape memory film by setting the second shape and subsequently heating the film to a tem- perature higher than the glass transition point, thereby causing the film to restore its basic shape.
