1. A method of polymerization to form a product polymer, the method comprising:
polymerizing, in the presense of light and of a polymerization catalyst, a first monomer (A) selected from a first class of monomers; and
polymerizing, in the absence of light and in the presence of the polymerization catalyst, a second monomer (B) comprising a non-functional olefin selected from a second class of monomers,
wherein the first class of monomers comprises monomers (A) that polymerize via a radical pathway in the presence of light, wherein the second class of monomers comprises monomers (B) that polymerize via an insertion pathway the absence of light.
