Abstract
The present invention is directed to the use of injection molding to form polymeric interlayers directly between two rigid substrates that are positioned so that after injection of the melted polymeric material and after cooling, the resulting multiple layer panel functions as a safety panel that can be used in any appropriate conventional safety glazing application. Methods of the present invention utilize a relatively low molecular weight polymer, multiple injection points, mold compression, and/or a heated substrate in order to facilitate the injection of polymer into the relatively narrow space between glazing substrates that is typically found in safety glazings.
