One mechanism useful in this process includes an intermediate coordination complex containing an alkene and is named for Cossee and Arlman. It's not metathesis, but a cyclic molecule is used in the ring-opening form of this process and includes less shrinkage.  This process may be initiated by azo- or peroxy- based initiators, light, or a redox reaction, among other methods. One form of this process begins with a molecule with a double bond and a free radical addition to that double bond. The "living" form of this process allows more control over the end product than the conventional "free radical" type of this process. This process may utilize Ziegler-Natta catalysts, and can be subdivided into initiation, propagation, transfer, and termination steps. For ten points, name this process in which large compounds are formed out of monomers.
