Abstract
Plastic resinous tubes, particularly for medical use is improved in blood compatibility when brought into contact with blood, by applying a low-temperature plasma treatment to inner surfaces of the tubes, which plasma is produced through electrodeless electric discharges by the effect of microwave to make it possible to prevent the tube from being heated in such a treatment. The inner surfaces of the tubes thus activated may be further subjected to an inner surface graft copolymerization treatment to enhance blood compatibility.
