ABSTRACT:
A polymer admixture is formed from a base polymer and thermoplastic copolymer additive including polar hard segments and polar and nonpolar soft blocks in graft or block copolymer form. The polymer admixture is characterized by increased contact angle hysteresis and is formed into blood and tissue-contacting surfaces of a biomedical device or into textiles. A preferred additive comprises a segmented block copolymer having polydialkylsiloxanes as nonpolar soft blocks, and a polyurethane as hard segments and a polyalkylene oxide as a polar soft block.
