ABSTRACT:
Articles having shape recovering properties and methods of using them are disclosed. An article is formed from a composition containing a norbornene polymer by forming said polymer into an article having a first shape, then deforming the article in the solid state to a second shape and cooling the article to a first temperature at or below the glass transition temperature of the polymer to retain said second shape, and finally heating said article to a temperature above the first temperature to recover the first shape.
