Collection: Polymerization Reagents

Polymerization Reagents — includes reagents for controlled polymerization, such as iodonium salts, anthraquinone derivatives, and dithiocarbonate and dithioate compounds that function as initiators, chain transfer mediators, or redox additives. These reagents enable precise control over molecular weight, dispersity, and polymer chain architecture during polymerization reactions.

These polymerization reagents are used by polymer chemistry researchers to carry out controlled radical polymerization techniques such as RAFT and ATRP, where dithiobenzoate and dithiocarbonate compounds act as chain transfer agents, while iodonium salts and anthraquinone derivatives are used as initiators or photoinitiators in light-based curing systems. Applications include the production of block copolymers, functional hydrogels, and photopolymer materials.

Example products in this collection: TCI H0193 99-93-4 4'-Hydroxyacetophenone, TCI B5598 60565-88-0 Bis(4-methylphenyl)iodonium Hexafluorophosphate, TCI A0104 121-71-1 3'-Hydroxyacetophenone, TCI B5661 62051-09-6 Bis(4-tert-butylphenyl)iodonium Tetrafluoroborate, TCI A0502 84-65-1 Anthraquinone, TCI B6065 870532-86-8 Bis(dodecylsulfanylthiocarbonyl) Disulfide, TCI A0508 153277-35-1 Sodium Anthraquinone-2-sulfonate Monohydrate, TCI B6066 27249-90-7 Benzyl Benzodithioate.

Reagent selection should consider the type of chain transfer mechanism desired, stability to heat or light, and high purity to achieve polymerization results with narrow dispersity that are reproducible. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
