The radical polymerization of monoethyl itaconate (MEI) was investigated in bulk and in solution at 60°C using a,a'-azobisisobutyronitrile as initiator. It was established that the obtained polymer poly(monoethyl itaconate) was insoluble in its monomer, implying that the bulk polymerization of MEI was a precipitation polymerization. The polymerization kinetics of MEI were discussed and compared to the polymerization kinetics of structurally similar alkyl itaconates. The homogeneous radical polymerization of MEI in tetrahydrofuran was not possible in the whole range of monomer/solvent concentration ratios, while the polymerization of MEI in methanol was homogeneous. The chain transfer constants to THF and methanol at 60°C were determined.
Ispitana je radikalna polimerizacija monoetil itakonata (MEI) u masi i u rastvoru na 60°C koristeći a,a'-azobisizobutironitril kao inicijator. Utvrđenoje da je nastali polimer poli(monoetil itakonat) nerastvoran u svom monomeru, tako da je polimerizacija MEI u masi zapravo taložna polimerizacija. Prodiskutovana je kinetika polimerizacije MEI u masi i uporedena sa kinetikom polimerizacije srodnih alkil itakonata. Homogena radikalna polimerizacija MEI u tetrahidrofuranu nije moguća u celom rasponu odnosa koncentracija monomer/rastvarač, dok je polimerizacija MEI u metanolu homogena. Odredene su konstante prenošenja aktivnosti lanca na THF i metanol na 60°C.
