Three series of segmented polyurethanes (PUs) with biomedical destination were synthesized using two-step catalyzed polymerization method. PUs with a broad range of hard segments content were obtained from the following components: 1,6-diisocyanatohexane or dicyclohexylmethane diisocyanate, poly(s-caprolactone)diol (olygodiol) and 1,4-butanedioI (chain extender). Chemical and physical structures were examined with the use of IR and DSC methods. Swelling behavior in water, oil and saline, contact angle and roughness were also investigated. The samples are crystalline, slightly hydrophilic with different surface properties, which can be controlled in a wide range by molar ratio of the components used for the synthesis. The results of hexane/water extracts tests do not exclude them to be applied for medical applications. The further studies to use the obtained PUs as medical non-solvent coatings are being continued.
