Resumen
The synthesis, polymerization behavior, and physical properties of a third vinyltriazole monomer family, the isomeric 1,4-N-vinyltriazoles, are reported. Xanthate-based reversible addition-fragmentation and transfer (RAFT) procedures were developed to obtain higher levels of N-vinyltrizaole incorporation and block copolymers based on trizaole homopolymers. Thermogravimetric analysis (TGA) of all the functionalized polymers demonstrated the influence of the aromatic triazole ring with similar onsets of weight loss around 350°C. The Tg's of the newly synthesized poly(1,4-N-vinyltriazole)s are found to be higher than the corresponding poly(1,4-Cvinyltriazole)s but lower than the poly(1,5-C-vinyltriazole)s. The polymer is found to exhibit high solubility in polar solvents such as dimethyl sulfoxide (DMSO) and N,N-dimethylformamide(DMF) and also in acidic and 5 wt % NaCl aqueous solutions.
