PURPOSE:To provide an antithrombus material which has excellent moldability and the excellent physical properties of a molded product, and beside prevents the generation of a reducing impurity by introducing a specified percent or more of a hydrocarbon group to the terminal of polyetheramide. CONSTITUTION:A hydrocarbon group is introduced to the terminal of polyetheramide, and the terminal is formed of hydrocarbonized polyetheramide resin having the number of hydrocarbon groups, being 5-100% of the number of total terminal groups, and an average molecular weight of 10000-100000. Polyetheramide being the main constituting unit of an antithrombus material is prepared through condensation of polyether having an amino group or a carboxyl group at a terminal and polyamide having a carboxyl group or an amino group at a terminal, and a representative main constituting unit has a repeating structure unit indicated in a formula (I) or (II). |
