Abstract
A method of polymerizing a first, and a second class of monomers to form product polymer. The first class of monomers polymerize via a radical pathway in the presence of light, and the second class of monomers polymerize via an insertion pathway in the absence of light.
Claims22
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.

A method of polymerization, the method comprising:
- (a) providing a polymerization mixture comprising a polymerization catalyst, a first monomer (A), and a second monomer (B), wherein the first monomer is selected from a first class of monomers that polymerize via a radical pathway in the presence of light, and wherein the second monomer comprises a non-functionalized olefin selected from a second class of monomers that polymerize via an insertion pathway in the absence of light;
- (b) effecting polymerization of the first monomer (A) by exposing the polymerization catalyst to light;
- and
- (c) effecting polymerization of the second monomer (B) by exposing the polymerization catalyst to darkness,
- to provide a product polymer.
