- W2348690981 abstract "A series of modified polyurethane elastomers(SPUs) with hydroxyl terminated polydimethylsiloxane containing carbonyl(PDMS-C) were synthesized with polytetramethylene ether glycol(PTMG) and PDMS-C as mixing soft segments by prepolymer method.The structures of SPUs were characterized by Fourier transform infrared spectroscopy,and the effects of PTMG/PDMS-C(mole ratio) on mechanical properties and high/low temperature resistance of SPUs were investigated.The results showed that PDMS-C was grafted on to polyurethane chain segment successfully.The tensile strength of SPU decreased with increasing PDMS-C content,but the retention rate of tensile strength was evidently larger than that of the polyurethane elastomers modified with common hydroxyl terminated polydimethylsiloxane.The high/low temperature resistance of SPUs was improved to a certain degree with the increase of PDMS-C content." @default.
