In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize … See more Step-growth and chain-growth are the main classes of polymerization reaction mechanisms. The former is often easier to implement but requires precise control of stoichiometry. The latter more reliably affords high … See more • Cross-link • In situ polymerization • Metallocene • Plasma polymerization • Polymer characterization See more WebPolymerization, or polymer synthesis, is a chemical reaction in which monomers are joined together by covalent bonding to form polymer structures.
