Heparinizable materials (IV). Surface-grafting on poly(ethylene terephthalate) of heparin-complexing poly(amido-amine) chains.
By a chemical process poly(amido-amine) chains have been grafted on the surface of poly(ethylene terephthalate) (Dacron) devices. After treatment, it was shown that the devices could adsorb significant amounts of heparin. Most of the adsorbed heparin can be recovered only by eluting at pH greater than 10 with NaOH solution.
