The segmented polyurethanes (SPU) of Vitur-RM trademark are widely used thrombosis resistant SPUs. The changes in the structure of their colloid level sizes and in stability characteristics were studied after incubation of SPU films in blood serum for a period of 1-2 years at 40°C. The small-angle X-ray scattering using linear coordination detector showed that the domain sizes did not change noticeably on incubations. The strength characteristics decreased by not more than by 10-15% during this of exposure. The characteristics investigated differed markedly from those found with samples with initially low strength, corresponding to the lowest limit of the Russian standard. |
