Latest Patents

Richard J Harrison holds a patent for the polymerization of ethylenically unsaturated monomers. This patent describes a method where ethylenically unsaturated, particularly acrylic, monomers are polymerized using a catalyst system that includes a manganese carbonyl initiator, an organic halogen reactive substrate, and an allylic halide chain termination agent. The manganese carbonyl initiator is preferably a dimanganese compound, specifically dimanganese decacarbonyl (Mn(CO)). The catalysis mechanism involves initiator homolysis and the formation of an organic free radical that acts as a chain initiator for polymerization. The reaction can be modified by including Lewis acids in the mixture, resulting in telechelic polymers that can be further functionalized or used to form block copolymers.
