Plastics are rendered nonthrombogenic by heparinizing them following a treatment with an amino alkyl tri alkoxy silane in an inert solvent. The solvent is preferably one capable of swelling the plastic. In the treatment of fluorocarbon plastics, a preliminary treatment with sodium is employed. The amino groups which become attached to the plastic are thus caused to bond heparin to the surface effectively to impart anticoagulating properties.
