Abstract

A series of Azo-Acrylate Polymer derivatives have been synthesized via free radical polymerization by using initiator (azobisisobutyronitrile, AIBN) both conventional heating methods (CH) and Microwave irradiation method (MI). The spectroscopic and thermal characterizations of the polymers have been described by FT-IR, 1H and 13C-NMR, and TG/DTA. The molecular weights of polymers were determined by GPC. According to the result obtained from FT-IR spectra, C=O stretching vibrations of monomers increased in case of polymers as expected. It was seen from 13C-NMR spectra that the shift of 10 ppm to the lower field relative to acryloyloxy azobenzene derivatives could be interpreted as a result of decreasing of electronic density around the carbon atom depending on the disappearance of the resonances of carbonyl group and ethylene group during the polymerization. Contrary to the Polydispersity Index (PDI) values in the polymers synthesized as using of CH method, the PDI values in the most of the polymers synthesized as using of MI method were lower.
