Abstract
Conventional free radical polymerization was employed for the synthesis of statistical copolymers of 2-vinyl pyridine (2VP) with either 2-butoxyethyl methacrylate (BuOEMA), di(ethylene glycol) methyl ether methacrylate (DEGMA) or oligo(ethylene glycol) methyl ether methacrylate bearing a side chain with an average number of 5 ethylene glycol units (OEGMA300). Copolymers having different compositions in the two monomers were obtained. The thermal decomposition of these statistical copolymers was studied by Thermogravimetric Analysis (TGA) and Differential Thermogravimetry (DTG). The Ozawa-Flynn-Wall (OFW) and Kissinger methodologies were adopted for the calculation of the activation energies of the thermal decomposition. The results of these studies were compared with those measured for the corresponding P2VP, PBuOEMA, PDEGMA and POEGMA300 homopolymers so as to correlate the structures of the copolymers with their properties.
