Ionic Polymerization Chip Development Service


Chemical knowledge and microfluidic processing technology allow Creative Biolabs to apply many important chemical transformation processes to flow microreactors, including important ion polymerization processes, helping our customers explore and challenge more chemical synthesis possibilities.

Ionic Polymerization

Ionic polymerization is a chain growth polymerization process in which ions or ion pairs are active centers, and usually includes anionic polymerization and cationic polymerization. Similar to the free radical polymerization process, ionic polymerization is also initiated by active compounds with special electrical properties. Common cationic polymerization initiators usually include strong acids, titanium, aluminum, tin halides and some salts, in addition to potassium, sodium, lithium, etc. Reactive metals and their compounds are often used as effective anionic initiators. During ionic polymerization, each charged chain end will interact with the opposite charge of the initiator.

Ionic Polymerization on Chip

The properties of polymers depend on the polymerized topology (cyclic, branched, linear), chemical composition (homopolymer, copolymer) and molecular weight distribution. For ionomers used in special fields, the accuracy of molecular weight distribution is particularly important. The molecular weight distribution of the product is affected by the polymerization reaction mechanism on the one hand, and also by process parameters such as temperature and concentration on the other hand. In addition, unlike free radical polymerization, the rate of ionic polymerization is not only determined by the chemical properties of monomers and the stability of free radicals, but also the reaction conditions, purity of reactants, and solvent polarity are also decisive factors for the success of ionic polymerization.
