Abstract
Biocompatibility of a series of thermoplastic elastomers based on a semicrystalline poly (tetramethylene terephthalate) hard segment and a poly (oxytetramethylene) soft segment has been evaluated by cell culture method, and compared with that of the segmented polyurethanes reported previously. The segmented polyesters showed a little different cell growth curve, increased initial cell attachment and similar rate of cell growth as compared with the segmented polyurethanes. Difference of cell behavior between the polyesters and the polyurethanes would be due to different domain microstructure.
