dc.description.abstract | In this paper, two samples of polyurethane (PU) crosslinked with hydroxy -functonal hyperbranched aliphatic polyester of the second pseudo generation were investigated. For the synthesis of these crosslinked PUs two different macrodiols were used: poly(tetramethyleneoxide) (PTMO) for PUPTMO and ethylene oxide-poly(dimethylsiloxane)-ethylene oxide (PDMS-EO) for PUPDMS-EO sample. Synthesized samples behave as elastomers and have yellow color. Obtained results show that swelling degree of the sample PUPDMS-EO in N-methyl-2-pyrrolidinon (NMP) determined at room temperature is higher than for the sample PUPTMO. It has been also observed that thermal properties of these polyurethane networks can be changed by incorporation of siloxane sequences in their structure. | en |
dc.description.abstract | U ovom radu su prikazani rezultati dobijeni ispitivanjem dva uzorka poliuretana (PU) umrežena hidroksi-funkcionalnim hiperrazgranatim alifatskim poliestrom druge pseudo generacije. Pri sintezi ovih umreženih PU korišćena su dva različita makrodiola: poli(tetrametilenoksid) (PTMO) za sintezu uzorka PUPTMO i etilenoksid-poli(dimetilsiloksan)- etilenoksid (PDMS-EO) za sintezu uzorka PUPDMS-EO. Sintetizovani uzorci se ponašaju kao elastomeri i imaju žuto obojenje. Određivanjem stepena bubrenja u N-metil-2-pirolidonu (NMP) pri sobnoj temperaturi pokazano je da uzorak PUPDMS-EO ima veći stepen bubrenja od uzorka PUPTMO. Primenom termogravimetrije konstatovano je da se uvođenjem siloksanskih sekvenci u korišćeni makrodiol može uticati na termička svojstva sintetizovanih umreženih poliuretana. | sr |
