PURPOSE: To obtain a material which can suppress coagulation of blood without using anti-coagulation agent by graft-polymerizing acrylic acid or methacrylic acid onto a polymer material and preparing an anticoagulant polymer material.
CONSTITUTION: An anticoagulant polymer material is prepd. by graft- polymerizing-acryllc acid or methacrylic acid on a general-purpose polymer material. This anticoagulant polymer material can be used as a material for medical instruments and tools which are possibly brought into contact with blood, e.g. a blood tube and a catheter which are medical tubes, a blood bag, a blood spit roll, a vial bottle, a test tube and a centrifugal tube and a syringe tube which are materials for medical containers, a culture medium such as a bacterium and a cell, a Petri dish and a vial, which are materials for culture tools and a sample cup, a sample rack, a funnel, a filter and a pipette which are diagnosis tools.
