Collection: Atom Transfer Radical Polymerization (ATRP) Reagents

Atom Transfer Radical Polymerization (ATRP) Reagents — covers initiator reagents and supporting ligands for controlled radical polymerization of the ATRP type, including branched bromoisobutyrate esters, functional silanes, and poly-substituted amines such as tetraethylethylenediamine. This group plays a role in controlling initiation and the active-dormant radical equilibrium during the chain polymerization process.

ATRP Reagents are used to grow polymer chains with controlled molecular weight and architecture, including preparation of block copolymers, branched polymers, and silane-based surface coating on particles or solid substrates. Materials science and polymer chemistry researchers use bromoisobutyrate-group initiators as the starting point of chains, while amine ligands such as TEEDA function to stabilize copper metal complexes that regulate the radical reaction.

Example products in this collection: TCI T3846 880339-31-1 3-(Triethoxysilyl)propyl 2-Bromo-2-methylpropanoate, TCI B6268 1095957-23-5 [11-[(2-Bromo-2-methylpropanoyl)oxy]undecyl]phosphonic Acid, TCI T3845 314021-97-1 3-(Trimethoxysilyl)propyl 2-Bromo-2-methylpropanoate, TCI B6381 213453-02-2 2-[(2-Bromo-2-methylpropanoyl)oxy]ethyl Acrylate, TCI T3844 688359-84-4 3-(Trichlorosilyl)propyl 2-Bromo-2-methylpropanoate, TCI B6384 213453-08-8 2-[(2-Bromo-2-methylpropanoyl)oxy]ethyl Methacrylate, TCI T3371 150-77-6 N,N,N',N'-Tetraethylethylenediamine, TCI B7067 248603-11-4 Ethylene Bis(2-bromoisobutyrate).

The selection considers the type of anchor group (trichlorosilyl, triethoxysilyl, or trimethoxysilyl for surfaces; acrylate or methacrylate for polymer chains), as well as the number of initiator groups in each molecule. All products are original Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
