Abstract: High Resolution Image Download MS PowerPoint Slide In order to envisage new solutions for complications associated with cardiovascular diseases, including the occlusion of small vessels, a family of random copolymers of poly(butylene trans -1,4-ciclohexanedicarboxylate) (PBCE), containing Pripol moiety, namely, poly(butylene trans -1,4-ciclohexaendicarboxylate/Pripol), were successfully synthesized. The copolymers display reduced crystallinity and stiffness compared with PBCE, exhibiting elastic modulus values that are comparable to those of materials previously investigated for similar applications. The stability of the materials under physiological conditions was demonstrated over an extended time. Cytotoxicity was confirmed by a direct contact assay with human umbilical vein endothelial cells (HUVECs), and blood compatibility was established by the absence of any change in the values of activated prothrombin time and activated partial thromboplastin time, in addition to the low adhesion of blood components. The results demonstrated that the ad hoc design is pivotal in regulating solid state and functional properties, thereby facilitating the development of innovative materials for vascular tissue engineering.
