Segmented thermoplastic polyurethane elastomers (PUSTE) comprise a family of very versatile materials with large potential for their applicability in different fields such as biomedicine. Among the PUSTEs the ones formed by polycarbonates diols and aliphatic diisocyanates are especially attractive due to their bioestability and biocompativility. In this work we present the results of morphological and mechanical characterization of different PUSTEs formed by 1,6-hexamethyene diisocyanate, 1,4-butanediol and a copolymer of polycaprolactone and polyhexamethylene carbonate diol, PCL-b-PHMC-b-PCL, synthesized with different ratios between rigid (HDI-BD) segments and the rubbery copolymer.

Palavras-chave : elastomeric segmented polyurethanes; aliphatic diisocyanate; polycarbonate; copolymers; structure properties relationship.
