Sequence-Controlled Polymers Using Macrocyclic ROMP

People Involved with this Research Area: 

Ring-opening metathesis polymerization (ROMP) generally relies on the ring strain within an unsaturated monomer to promote and control the polymerization process. Through the invention of an enyne containing small molecule “polymerization trigger,” fast and direction polymerizations can be achieved without the prerequisite of ring strain. This allows for facile introduction of complex sequences and functionality into the backbone of the resulting polymer, while still maintaining control over parameters such as molecular weight and molecular weight distribution.
