Resumen:
Free radical polymerization of
dialkyl fumarates (R: isopropyl, cyclohexyl, 2-ethylhexyl,
2-phenylethyl) under microwave irradiation was investigated. The
polymerizations were carried out at different power irradiations and initiator
concentrations (benzoyl peroxide, BP)
and the effect of the monomer structure on the conversion, average molecular
weights and the polydispersity index (Mw/Mn) was
analyzed. It was found a significant enhancement of the rates of
polymerization, as compared with those obtained under thermal conditions.
