Lisandpolümeerimine is a chemical process used to create polymers. It involves the addition of monomers to a growing polymer chain without the loss of any atoms. This type of polymerization typically proceeds through a chain reaction mechanism, which can be initiated by various species such as free radicals, cations, or anions. The process continues as monomers are sequentially added to the active end of the growing chain.

One common example of lisandpolümeerimine is free radical polymerization. In this process, a free radical initiator is used to generate free radicals, which then attack the double bond of a monomer, creating a new radical species. This new radical then reacts with another monomer, propagating the chain reaction. Chain transfer reactions can occur, where the radical activity is transferred to another molecule, either a monomer or a solvent, leading to the termination of one chain and the initiation of another.

Lisandpolümeerimine is a versatile method used in the synthesis of a wide range of polymers, including polyethylene, polypropylene, and polystyrene. The specific conditions of the reaction, such as temperature, pressure, and the presence of catalysts or inhibitors, can be controlled to influence the molecular weight, architecture, and properties of the resulting polymer. This controllability makes lisandpolümeerimine a crucial technique in polymer science and industry for producing materials with desired characteristics for various applications.
