Precision integral articles

An article comprising a surface and an interior core, the article prepared by:

• mixing together a dead polymer, a reactive plasticizer, an initiator and, optionally, other additives to form a semi-solid polymerizable core composition;
• optionally shaping the core composition into a desired geometry;
• exposing the core composition to a surface-forming composition to form a semi-solid gradient composite material;
• and
• exposing the gradient composite material to a source of polymerizing energy to give the article, wherein the composition of the surface material is distinct from the composition of the core material, and wherein the surface and the core are an integral monolithic entity.
