Abstract
We present a comparative study of the biostability and structural organization of polyurethanes (PU) having chemistries of those of commercial biomedical interest. The soft segments are poly(carbonate)diol (PC), poly(tetramethylenoxide)diol (PTMO) and a mixed macrodiol composed of poly(hexamethylenoxide)diol (PHMO) and poly(dimethylsiloxane) (PDMS). In PDMS based PU, PDMS units are completely phase separated from the hard segments due to their highly non-polar character. However, 'interphase' mixing is achieved for the PDMS end group segments and the PHMO component. PTMO and PC-based PU present a much lower degree of phase separation and larger interdomain spacings than PDMS based PU. The mechanical properties and biostability of the samples will also be compared.
