Synthesis, polymerization, and copolymerization of aliphatic vinyl azide

Abstract

ABSTRACT:The synthesis and characterization of a fully aliphatic polymeric azide by polymerization of its vinyl monomer 1,3-diazidoisopropyl methacrylate (DAIPM) is reported. DAIPM was prepared by azidation of epichlorohydrin followed by coupling with methacrylic acid. Homopolymer and copolymers with methyl methacrylate were prepared and characterized by IR, GPC, TGA, DTA, and elemental analyses. These polymers are freely soluble in organic solvents like dichloromethane, tetrahydrofuran, dimethyl formamide, acetone, and so forth and do not crosslink on storing. The polymers show decreased thermal stability with an increase in azide content and undergo exothermic decomposition on heating.

Room‐temperature RAFT copolymerization of 2‐chloroallyl azide with methyl acrylate and versatile applications of the azide copolymers

“…Because of the azide group sensitivity to heat and UV light, conventional radical polymerization and photopolymerization are not suitable for the preparation of azide polymers. Until now, there are only a few articles published on the free radical polymerization of vinyl azide monomers 22–25. We have been trying to develop facile and effective strategies for the preparation of azide polymers.…”

“…Until now, there are only a few articles published on the free radical polymerization of vinyl azide monomers. [22][23][24][25] We have been trying to develop facile and effective strategies for the preparation of azide polymers. Although living free radical polymerization has been first successfully used to prepare azide polymers by c-ray initiation in our lab, [26][27][28] c-ray source is not avail-able for every laboratory.…”

A Facile Strategy for the Preparation of Azide Polymers via Room Temperature RAFT Polymerization by Redox Initiation

“…Until now, there are only a few papers published on the free-radical polymerization of vinyl azide monomers. [23][24][25][26] We [27][28][29] reported previously an approach for syntheses of azide and acyl azide polymers via living free-radical polymerization under g-ray irradiation at 0 8C or room temperature. Although g-ray initiated living free-radical polymerization has been successfully used to prepare azide polymers, g-ray source is not available in every laboratory.…”
