摘要

An iodine-mediated reversible deactivation radical polymerization (RDRP) integrating reverse iodine transfer polymerization (RITP)

reversible complexation mediated polymerization (RCMP)

and atom transfer radical polymerization (ATRP) enabled

in situ

generation of alkyl iodide initiators. Their cooperative interplay enables controlled polymerization of methacrylates and provides insight into multi-mechanism radical polymerization.

Abstract

Iodine is an attractive candidate for living radical polymerization owing to its strong halogen bonding ability and the vigorous C―I bond

enabling diverse mechanisms including iodine transfer polymerization (ITP)

reverse iodine transfer polymerization (RITP)

reversible complexation medi

ated polymerization (RCMP)

and atom transfer radical polymerization (ATRP). Among them

iodine-mediated ATRP stands out for its high activation rate constants

low equilibrium constants

and convenient post-polymerization modification. However

the use of alkyl iodides as initiators remains challenging because they are thermally and photochemically unstable. To solve this question

RITP mechanism was incorporated into the ATRP for the

in situ

generation of the alkyl iodide from I

. Further studies revealed that the ATRP ligands could also trigger the RCMP mechanism. Kinetic studies

radical trap experiments

and density functional theory (DFT) calculations clarified the contributions of each mechanism. This RITP/RCMP/ATRP ternary polymerization avoids the use of unstable initiators and achieves controlled polymerization of various monomers.
