Methods of producing an elastomer are disclosed that include (I) applying an actinic radiation curable composition preferably selected from a urethane (meth)acrylate, an allophanate urethane (meth) acrylate or a lactone-containing (meth)acrylate to a substrate at a thickness of at least 0.25 mm (10 mils); (II) exposing the composition ultraviolet radiation to produce a cured film; and (III) removing the film from the substrate. Related compositions are also disclosed. La présente invention concerne des procédés de production d'un élastomère, qui consistent: (I) à appliquer sur un substrat, selon une épaisseur d'au moins 0,25 mm (10 mils), une composition polymérisable par rayonnement actinique choisie de préférence parmi un (méth)acrylate d'uréthane, un (méth)acrylate d'uréthane à groupes allophanate et un (méth)acrylate contenant du lactone; (II) à exposer la composition à un rayonnement ultraviolet en vue de produire un film polymérisé; et (III) à retirer le film du substrat. L'invention concerne également des compositions associées.
