Abstract

U sklopu ovog rada istražena je kinetika polimerizacije 1,3–dinitrozobenzena u čvrstom stanju
u različitim topokemijskim okolinama. 1,3–Dinitrozobenzen sintetiziran je redukcijom 1,3–
dinitrobenzena do odgovarajućeg hidroksilamina, koji je potom oksidiran do 1,3–
dinitrozobenzena. Kinetika polimerizacije 1,3–dinitrozobenzena istražena je nakon kriogene
fotolize polimera u KBr pastili pri kriogenim uvjetima te nakon kriogene depozicije para
monomera na pločicu cezijeva jodida. Kinetike reakcija polimerizacije praćene su pri različitim
temperaturama vremenski razlučenom IR spektroskopijom. Iz temperaturne ovisnosti
koeficijenta brzina reakcija određeni su aktivacijski parametri za reakciju polimerizacije 1,3–
dinitrozobenzena.

Abstract (english)

Within this work, kinetics of solid–state polymerization of 1,3–dinitrosobenzene in different
topochemical environments was studied. 1,3–Dinitrosobenzene was synthetised by reduction
of 1,3–dinitrobenzene to corresponding hydroxylamine, which was subsequently oxidized to
1,3–dinitrosobenzene. Kinetics of polymerization of 1,3–dinitrosobenzene was studied after
cryogenic photolysis of polymers in KBr pellet and after cryogenic deposition of monomers on
cesium iodide surface. Kinetics of polymerization was followed by time–resolved IR
spectroscopy at different temperatures. Activation parameters for the polymerization reaction
of 1,3–dinitrosobenzene were calculated from the temperature dependence of the reaction rate
constants.
