    Abstract: A process for making a multilayered article, the process comprising the steps of: (A) Providing a mold comprising: (1) A mold housing comprising (a) at least one injection port, and (b) defining a mold cavity within which are positioned two deformable, pre-molded polymeric sheets; and (2) A removable, hollow core equipped with at least one vent, the removable, hollow core positioned between and space apart from the two polymeric sheets; (B) injecting under high pressure a viscous, crosslinkable, thermoplastic polymer into the mold cavity between the two polymeric sheets and around the removable core, (C) Drawing a vacuum on the mold cavity through both the vent in the mold housing and the vent in the removable, hollow core before, during and/or after the polymer has been injected into the mold; (D) Forming a less than fully cured multilayered article in the mold cavity; and (E) Removing the less than fully cured multilayer article from the mold cavity.
