Abstract: Provided herein are processes for the generation of composite polymer materials utilizing a single resin. The processes utilize diffusion between a region undergoing a polymerization reaction preferentially polymerizing one monomer component and an unreactive region. Diffusion and subsequent/concurrent polymerization results in a higher concentration of the more reactive monomer component in the reacting region and a higher concentration of the less reactive monomer components in the unreactive region. The unreactive region may be later polymerized. In embodiments, photopolymerization is used and the regions are generated by a mask or other mechanism to pattern the light.
