| 摘要 |
New polymers substituted with sulphonated polyethylene oxide which have an improved blood compatibility. They are obtained by substitution of a polymer substrate which has active sites of amide groups or acid amide groups, such as a polyurethane, a polyamide and a polyacrylamide, with sulphonated polyethylene oxide [PEO-(SO3H)n]. The polymers according to the present invention are valuable as materials of construction for artificial organs for the circulatory system, which are intended to be in contact with blood, such as artificial hearts, artificial blood vessels, artificial kidneys and the like.
