ABSTRACT:
Functionally gradient polymeric materials are formed by a process that utilizes an ascending polymerization front. A polymerization front is initiated in a reaction vessel containing a monomer solution. Additional monomers or resins are added on top of the polymerization front to maintain a substantially constant level. The composition of the monomers and/or additives are varied as they are added to the reaction vessel to form a functionally gradient polymeric material.
