A new class of materials based on crosslinked poly (ester-urethane) containing low proportions of ionic liquid were synthesized using biobased sulfonated oligoester diol, trimethylol propane (TMP), 4,4′-methylene bis(cyclohexyle isocyanate) (HMDI) and 1-butyle-3-methylimidazolium acetate (BMIMAc). Sulfonated oligoester with a well-controlled molar mass was first obtained by melt polycondensation catalyzed by Ti(OBu)4. The resulting products were characterized by, 1HNMR, DSC and MALDI-TOF MS techniques. The systems of crosslinked poly (ester-urethane) and ionic liquid were obtained via a one-shot process. FTIR tech. was used for a more effective control of crosslinking reaction. The Thermomech. anal. of the resulting materials were performed by DSC and DMA technique. Furthermore, the hydrolytic and oxidative degradation study revealed that the degradation of systems mainly depends on the content in ionic liquid and the crosslinking degree of networks.
Journal of Polymer Research published new progress about Complex modulus, tan δ. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
