ABSTRACT:
The invention is directed to a method for manufacturing heat-activatable articles from a synthetic thermoplastic material on which a shape memory is impressed by introducing molecular orientations and molecular structures. These articles, after the impressing of the shape memory, are subsequently subject to a further change in shape, at least in sub-regions thereof. The shape memory is influenced by this further change in shape.
