Seleno‐containing poly(vinyl acetate) prepared by diselenocarbonates‐mediated controlled free radical polymerizations

Abstract

The living free radical polymerizations of vinyl acetate (VAc) were successfully achieved in the presence of a novel organic selenium compound (diselenocarbonates), with 2,2 0 -azobisisobutyronitrile (AIBN) as the initiator. The living characteristics of the VAc polymerization were confirmed by the linear first-order kinetic plots and linear increase of molecular weights (M n ) of the polymers with monomer conversions, while keeping the relatively low molecular weight distributions.In addition, the end of the polymers contains selenium element which may be useful in biotechnological and biomedical applications.

A Straightforward Method for Preparing Well-Defined Responsive Diselenide-Containing Polymers Based on ATRP

“…However, due to the limitation of selenide group, the polymerization showed limited controllability on the structure of polymers. Our group has reported the LRP of vinyl monomers based on the diselenocarbonyl compounds, e.g., selenium‐mediated radical polymerization (SeRP) . Such system showed moderate to well‐controlled polymerization behavior for most of the vinyl monomers, such as styrene, (meth)acrylates, vinyl acetate, etc.…”

“…[6][7][8][9][10][11][12][13] They found that after oxidation or reduction, the hydrophobicity of the polymers could be enhanced, which reported the LRP of vinyl monomers based on the diselenocarbonyl compounds, e.g., selenium-mediated radical polymerization (SeRP). [20][21][22] Such system showed moderate to well-controlled polymerization behavior for most of the vinyl monomers, such as styrene, (meth)acrylates, vinyl acetate, etc. Polymers with tailored structures were obtained.…”

A new selenium-based RAFT agent for surface-initiated RAFT polymerization of 4-vinylpyridine

“…Because of the analog of selenium (Se) with sulfur (S) in electronic structure, selenium-based RAFT agents have also been explored in RAFT polymerization [23e25]. Recently, Zhu et al [25] synthesized seleniumbased RAFT agents and used them as the RAFT agents for vinyl acetate polymerization. They [24] also reported the RAFT polymerization of styrene using the similar phosphinodiselenoic esters under UV irradiation.…”
