Abstract
Ovaj diplomski rad sastoji se od dvije cjeline: istraživačkog i metodičkog dijela. U sklopu prvog dijela proučena je polimerizacija 1,4–dinitrozobenzena u kriogenim uvjetima. Eksperimentalni dio rada obuhvaća dobivanje monomera navedenog C–nitrozo spoja dvjema metodama, sublimacijom te fotolizom UV–zračenjem pri niskoj temperaturi i njegovu ponovnu polimerizaciju. Ispitan je i utjecaj topokemijske sredine na brzinu polimerizacije te na omjer nastalih E– i Z–azodioksi polimera. Kinetika polimerizacije praćena je IR–spektroskopijom, a dobiveni podatci interpretirani su Avrami–Erofeevim modelom za opis reakcija u čvrstom stanju. Iz dobivenih konstanti brzina reakcije određene su energije aktivacije ovih kemijskih reakcija. U metodičkom dijelu pod naslovom Prirodni i sintetski polimeri – primjer dobre nastavne prakse predložena je nastavna priprema temeljena na obrazovnoj strategiji učenja otkrivanjem za obradu sadržaja vezanih uz prirodne i sintetske polimere, primjerene uzrastu učenika četvrtog razreda gimnazije. Načinjen je pregled i kritički osvrt udžbeničke i stručne literature na zadanu temu, postavljeni nastavni ciljevi te odabrani i prilagođeni pokusi. Na temelju njih predložen je i metodički oblikovan nastavni dvosat obrade novih nastavnih sadržaja, uključujući pripremu principa 'zelene kemije' i integrirane nastave.
Abstract (english)
This Diploma thesis consists of two parts: the research part and the methodological part. Within the first part, the polimerisation of 1,4–dinitrobenzene in cryogenic conditions was studied. The experimental part of the work involves preparation of monomer of said C–nitroso compound using two methods, sublimation and UV photolysis at low temperature and its re–polymerization. Topochemical environment influence on the rate of polymerization is also examined, as on the ratio of E– and Z–azodioxy polymers. The kinetics of polymerization was monitored by IR spectroscopy and the obtained data are interpreted by Avrami–Erofeev model for description of solid state reactions. From the obtained reaction rate constants the activation energy of these chemical reactions was determined. The methodological part of the Thesis entitled Natural and synthetic polymers − an example of good teaching practice presents the educational preparation based on educational strategy of discovery learning associated with natural and synthetic polymers, appropriate to students of the fourth grade of high school. An overview and a critical review of textbooks and professional literature on a given topic are given, learning objectives and selected and adapted experiments are set. Based on these, a two hour teaching lesson of new content is proposed, including preparation of 'green chemistry' principle and integrated teaching.
