1. Title of theresearchtopic: Preparation of biologicallydegradablepolymersviachemicalrecycling of PET waste
Description of theresearchtopic:
Solvolysis of PET wastebyusingdifferentreagentsinordertoproducevalueaddedproducts. Forthesolvolysisdifferentalcohols, acids, and aminesareused. The intermediatesresultedbysolvolysis of PET wastewill be characterizedbyfunctionalgroupanalysis, gelpermeationchromatography (GPC), high performance liquidchromatography (HPLC), thermalanalysis (TGA, DSC, DMTA), FTIR and NMR spectroscopy, oscillationrheometry and mechanicalinvestigations. The finalproductswill be pressedintoplates and theirbehaviourwill be investigatedincompost. Byproducingbiodegradablepolymersfrom PET waste a greatcontribution is giventothe life cycle of thematerial.
2.Title of theresearchtopic: Synthesis of biologicallydegradablepolymers
Description of theresearchtopic:
Ouraim is thesynthesis of biologicallydegradablepolyesters and polyesteramides. Forthispurposepoly(ethyleneadipate) (PBA), poly(ethylenesuccinate) (PBS) and poly(ethylenesuccinate-adipate) (PBSA) will be synthesized. The effect of othermonomerssuchascyclohexanedimethanolorterephthalicacidontheproperties of polyestersaswellasontheirbiodegradabilitywill be investigated. Forpreparingpolyesteramidesdicarboxylicacids and differentamino-alcoholssuchasethanolaminewill be used. The synthesizedpolyesters and polyesteramideswill be characterizedbyfunctionalgroupanalysis, gelpermeationchromatography (GPC), high performance liquidchromatography (HPLC), thermalanalysis (TGA, DSC, DMTA), FTIR and NMR spectroscopy, oscillationrheometry and mechanical testing. The finalproductswill be pressedintoplates and theirbehaviourwill be investigatedincompost.
3. Title of theresearchtopic: Preparation of environmentalydegradablepolymerblends
Description of theresearchtopic:
Naturalpolymersbasedonrenewableresorcessuchasthermoplasticstarch (TPS), polylacticacid) (PLA), poly(hydroxylalcanoate)s (PHB) will be compoundedwiththenewlysynthesizedbiodegradablepolyesters and polyesteramides. Theircompatibility and biodegradabilityincompostwill be tested. The compoundswill be investigatedbythermalanalysis (TGA, DSC, DMTA), oscillationrheometry, digital and polarizationopticalmicroscopy (DOM, POM) scanningelectronmicroscopy (SEM). Compatibilitywith standard plastics (LDPE, PET) mayalso be tested. Microbiologicalinvestigationswill be carried out incooperationwith Szent István university Gödöllő.
