polyadditioksi

Polyaddition, also known as polyadditioksi, is a chemical reaction in which two or more molecules combine to form a single product. This process is a type of addition polymerization, where monomers (simple molecules) with two or more double or triple bonds between carbon atoms react to form a polymer (a large molecule composed of many repeated subunits). The reaction typically proceeds through a radical mechanism, involving the formation of reactive intermediates called radicals.

The polyaddition reaction is characterized by the absence of by-products, as all reactants are incorporated into the polymer chain. This makes it a highly efficient process for producing polymers with specific properties. The reaction can be initiated by various methods, including thermal, photochemical, or chemical initiation. The choice of initiator and reaction conditions can significantly influence the molecular weight, molecular weight distribution, and microstructure of the resulting polymer.

Polyaddition reactions are widely used in the synthesis of various polymers, including polybutadiene, polyisoprene, and polychloroprene. These polymers find applications in the production of rubbers, adhesives, coatings, and other materials. The versatility of polyaddition reactions makes them an important tool in polymer chemistry, enabling the design and synthesis of polymers with tailored properties for specific applications.
