When ATRP is employed to form each block in a block copolymer the composition and molecular weight and, to some extent, the PDI of each block can be independently controlled. Multifunctional initiators can also be used in the process to prepare ABA or AB-star multi-armed block copolymers.(2,3)

2025年1月9日 · Atom transfer radical polymerization (ATRP) is a synthetic method that harnesses radical polymerization to yield well-defined polymers of controlled architecture from a...

原子转移自由基聚合( ATRP，Atomic transfer radical polymerization ) 是可逆失活自由基聚合的一个例子。 与其对应物ATRA或原子转移自由基加成一样，ATRP 是一种利用过渡金属催化剂形成碳碳键的方法。

2024年10月16日 · In this study, we successfully synthesized PVDF-based block copolymers using a metal-free ATRP approach. We synthesized a PVDF macroinitiator containing C─Br bonds at both ends of the chain and used perylene as an organic photoredox catalyst to control the polymerization process.

ATRP is based on an inner sphere electron transfer process, (4) which involves a reversible homolytic (pseudo)halogen transfer between a dormant species, an added initiator or dormant propagating chain end (R-X or R-P n -X) and a transition metal complex in the lower oxidation state (Mt m /L n), resulting in the formation of propagating radicals...

2014年1月1日 · ATRP is a versatile synthetic tool that enables the preparation of new (co)polymers with precisely controlled molecular weight, relatively low dispersities (Mw /M n < 1.1), composition (block, graft, alternating gradient …

Atom Transfer Radical Polymerization (ATRP) is among the most effective and most widely used methods of controlled radical polymerization (CRP). ATRP allows scientists to easily form polymers by putting together component parts, called monomers, in a …
