Abstract
In an apparatus for the reaction injection molding of a shaped article from a polymerizable flowable resin-forming composition, once such composition has attained a predetermined increased level of viscosity as measured in situ within the mold cavity, an amount of pressure is applied to the polymerizing composition which is sufficient to maintain any entrapped gas(es) dissolved therein and/or to prevent the composition from pulling away from mold cavity surfaces.
