Crosslinked Polyurethanes Based on Hyperbranched Polymers
Apstrakt
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.
