Abstract:Iskanje spojin iz obnovljivih virov za proizvodnjo plastike brez uporabe nafte je postalo osrednja raziskovalna tema na področju polimerov. To ni posledica le naraščajoče okoljske ozaveščenosti in prizadevanj za trajnost, temveč tudi izčrpavanja zalog fosilnih goriv. Posledično sistemi reakcij, ki sledijo načelom »zelene kemije«, pridobivajo vse več pozornosti. V tem kontekstu imajo tudi terpeni velik potencial — naravne spojine, ki jih najdemo v biomasi in so glavne sestavine eteričnih olj in smol. Njihova kemijska struktura temelji na izoprenu, kar omogoča uporabo dvojnih vezi za nadaljnjo polimerizacijo. Med številnimi sintetskimi metodami se kot obetavna alternativa uveljavlja tiol-enske polimerizacije. Ta temelji na hitri reakciji med dvojnimi vezmi alkenov ali trojnimi vezmi alkini in tiolskimi skupinami. Metoda poteka v blagih reakcijskih pogojih, pogosto ob prisotnosti UV-svetlobe, brez zaviralnega učinka kisika in brez potrebe po organskih topilih, kar omogoča nastanek zamreženih polimerov z odličnimi mehanskimi lastnostmi. V tej nalogi bomo sintetizirali biopolimerne materiale na osnovi terpenov (mircen, karvon) in večfunkcionalnih tiolov z uporabo masne tiol-enske klik-polimerizacije. Cilj je razviti nove zamrežene tiol-enske polimere, pri katerih bomo z uravnavanjem molskega razmerja terpen:tiol izboljšali mehanske lastnosti materialov in optimizirali reaktivnost terpenov pri tvorbi zamreženih kopolimerov.

Title:Sustainable biopolymers: synthesis of crosslinked polymeric materials based on terpenes via thiol-ene polymerization
Abstract:The search for compounds from renewable resources for the production of plastics without the use of petroleum has become a central research topic in the field of polymers. This is not only the result of increasing environmental awareness and sustainability efforts, but also of the depletion of fossil fuel reserves. Consequently, reaction systems that follow the principles of “green chemistry” are gaining growing attention. In this context, terpenes also have significant potential—natural compounds found in biomass, where they are the main constituents of essential oils and resins. Their chemical structure is based on isoprene, which enables the use of double bonds for further polymerization. Among the many synthetic methods, thiol-ene polymerization is emerging as a promising alternative. It is based on the rapid reaction between alkene double bonds or alkyne triple bonds and thiol groups. This method proceeds under mild reaction conditions, often in the presence of UV light, without the inhibitory effect of oxygen and without the need for organic solvents, enabling the formation of cross-linked polymers with excellent mechanical properties. In this thesis, we will synthesize biopolymeric materials based on terpenes (myrcene, carvone) and multifunctional thiols using bulk thiol-ene click polymerization. The aim is to develop new cross-linked thiol-ene polymers, where by adjusting the molar ratio of terpene:thiol, we will improve the mechanical properties of the materials and optimize the reactivity of terpenes in the formation of cross-linked copolymers.
Keywords:thiol-ene polymerization, terpenes, myrcene, carvone, polyHIPE, porous polymers
