The present invention provides methods of manufacturing a viscoelastic article by a process that includes coating a release surface with a curable composition, contacting a second release surface with the exposed urface of the curable composition and at least partially curing the composition. The composition is then removed from both release urfaces. Viscoelastic articles manufactured according to these methods may be constructed to be self- supporting.
La présente invention concerne des méthodes de fabrication d'un article viscoélastique, par un procédé qui consiste à: enduire une surface antiadhérente d'une composition polymérisable; placer une seconde surface antiadhérente au contact de la surface exposée de la composition polymérisable; et polymériser au moins partiellement la composition. La composition est ensuite retirée des deux surfaces antiadhérentes. Des articles viscoélastiques auto-portants peuvent être fabriqués selon les procédés de l'invention.
