Abstract:
Provided is a method for preparing a polymeric article including introducing a polymerizable composition into a mold; sealing the composition within the mold using a sealing means; placing the mold into a convection cure oven; subjecting the polymerizable composition to a cure cycle sufficient to partially cure the composition; extracting the mold from the convection cure oven; optionally, removing the sealing means from the mold; placing the mold into an auxiliary curing chamber which is placed into the convection cure oven, or placing the mold into an auxiliary curing chamber which is within the convection cure oven; subjecting the polymerizable composition to a further cure cycle to complete polymerization of the composition, thereby forming a cured polymeric article; and removing the cured polymeric article from the mold.
