vaihekasvupoly

Vaihekasvupoly is a term used in polymer science to describe a specific mechanism of polymer chain growth. It refers to a process where polymerization occurs through the addition of monomers to reactive sites, and these reactive sites are then propagated along the growing polymer chain. Unlike chain growth polymerization where monomers directly add to an initiated radical or ion, in vaihekasvupoly, the reactive center is transferred or moves along the chain. This often involves a series of steps where a monomer unit is incorporated, and then a new reactive site is formed or activated at the end of the newly added unit. This can lead to polymers with specific microstructures or architectures depending on the precise nature of the vaihekasvupoly mechanism. Examples of polymerization mechanisms that can exhibit vaihekasvupoly characteristics include certain types of coordination polymerization and some ring-opening polymerizations where the active center migrates. The control over molecular weight and dispersity can be influenced by the efficiency and rate of these propagation steps. Understanding vaihekasvupoly is crucial for designing polymers with tailored properties for various applications.
