Synthesis and Characterization of Functional Polymers with Conjugate Chains

Abstract

New functional polymers with conjugate chains were synthesized by dehalogenation of dichloromaleimides or diiodomaleimides. The dechlorination reaction of dichloromaleimides was carried out in the presence of dust-activated Zn or Pd, and the deiodination of diiodomaleimides was carried out by thermal decomposition. The new structures were characterized by spectral methods (NMR, IR, UV-Vis), as well as by thermal analysis (TGA, DSC).

Synthesis and characterization of new nitrogen-rich polymers as candidates for energetic applications

“…There is a considerable interest in polyvinyltetrazoles (PVT) containing a large amount of nitrogen because of their powerful energetics, [1][2][3] interpolymer complexity, [4,5] biological activity, high thermostability, [6][7][8] and good solubility in various solvents, [9] exhibiting wide applications including dynamite, polyelectrolytes, [10,11] distinctive complex, [12] biocompatible material of different natures, and oxygen enriching membrane. [13][14][15] The investigation on the radical (co)polymerization, [16] radiation-induced bulk polymerization, [17] solution interdiffusion, [18,19] solution properties and kinetics of solution formation in various media, [20] rheological properties, [21] swelling thermodynamics, [22] and thermal degradation and its kinetics and mechanism of the PVT has been reported. Well-known technique for the preparation of the PVT is traditional radical polymerization of 5-vinyltetrazole monomer, [23,24] Considering that the 5-vinyltetrazole monomer is not readily available at the present time because of the absence of commercial source of 5-vinyltetrazole and also the difficulty in the synthesis of the 5-vinyltetrazole, [25][26][27] a new and powerful technique for the preparation of the PVT by tetrazole cyclization of polyacrylonitrile (PAN) could be a real challenge.…”
