초록

Poly(etherurethane urea) (PEUU) elastomers when employed as biomedical devices may be susceptible to extraction upon implantation. Four PEUU elastomers containing a single PEUU formulation, but varying in terms of their additives, were subjected to an in vitro extraction procedure. The additives in the PEUUs were Methacrol 2138 F at 5 wt% and Santowhite powder at 1 wt% levels. Only 1-2 wt% of the PEUUs was extractable with methanol. Fourier transform infrared spectroscopy (FT-IR) furnished qualitative and quantitative information on the extractables. The extractables consisted of a PEUU component that on the average was richer in soft segment than the bulk PEUU, and the two additives, Methacrol 2138 F and Santowhite powder.
