 Chain-growth polymerization

Chain-growth polymerization, also known as chain reaction polymerization, is a method of synthesizing polymers in which the structure of the polymer grows by the sequential addition of monomer units. This process typically involves three main steps: initiation, propagation, and termination. 1. **Initiation**: This step begins with the formation of reactive species, such as free radicals, cations, or anions, which are necessary to initiate the polymerization process.
