摘要:
The invention relates to thermoplastic polyurethanes modified with segmented siloxane block copolymers which are based on relatively high molecular weight dihydroxy compounds, diisocyanates, and difunctional chain extenders. The application also relates to their use in the medical field, and particularly as a catheter material.
