Group Transfer Polymerization (GTP) Reagents

Collection: Controlled Polymerization Reagents (Other)

Controlled Polymerization Reagents (Other) — gathers silyl ketene acetal initiators, Lewis acid catalysts such as lanthanide triflates, and coordinating bases that direct chain growth in Group Transfer Polymerization and Immortal Polymerization systems outside conventional radical pathways.

Reagents in this category are used by polymer chemists to build poly(methyl methacrylate) chains with a narrow molecular weight distribution through Group Transfer Polymerization, and to insert additional monomers without terminating the active center via the Immortal Polymerization approach. Lewis acid catalysts and coordinating bases activate acrylic monomers or epoxides, while organometallic reagents such as alkylzinc and Grignard reagents act as initiators and chain-end formers in block copolymer synthesis.

Example products in this collection: TCI T2392 82113-66-4 N-(Trimethylsilyl)bis(trifluoromethanesulfonyl)imide, TCI D1789 31469-15-5 Dimethylketene Methyl Trimethylsilyl Acetal, TCI T1610 54761-04-5 Ytterbium(III) Trifluoromethanesulfonate, TCI D3214 557-20-0 Diethylzinc (ca. 15% in Hexane, ca. 1mol/L), TCI T1359 917-23-7 Tetraphenylporphyrin (Chlorin free), TCI D3902 557-20-0 Diethylzinc (ca. 15% in Toluene, ca. 1mol/L), TCI T1295 23868-34-0 Tetrabutylammonium Bifluoride, TCI I0542 1068-55-9 Isopropylmagnesium Chloride (ca. 13% in Ethyl Ether, ca. 1mol/L).

Pay attention to the solvent and molar concentration of organometallic reagents such as diethylzinc or Grignard reagents supplied in hexane, toluene, or ether solutions, as well as the water-free purity level, to maintain the activity of the Lewis acid catalysts and coordinating bases. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
