Preparation and characterization of poly[2-(4-pentenoyloxy)ethyl methacrylatel

Polimery 2002, No 11-12, 813


Summary

A new multimonomer, the poly[2-(4-pentenoyloxy)ethyl methacrylatel (PPEM) has been synthesized by Schotten-Bauman's esterification of poly(2-hydroxyethyl methacrylate) with 4-pentenoy1 chloride. Its chemical structure was confirmed by means of FTIR, lH NMR, 13C NMR spectra as well as by elemental analysis. Differential scanning calorimetry (DSC) and thermogravimetry (TG) were used to determine the thermal behavior of the PPEM. It was seen, that thermal polymerization of side vinyl groups and thermal decomposition of the multimonomer appear within the 247-380 oC range (under nitrogen). Introduction of 1 wt. % of AIBN under nitrogen reduces PPEM polymerization temperature to 136 °C. PPEM undergoes photopolymerization at room temperature to crosslinked products.
