Notes:
Surface grafting of low-molecular weight polyamines and poly(amino-amides) onto Dacron fabrics was performed by two different methods. The first one involves chlorosulfonation followed by a reaction with a polyamine such as triethylenetetramine, and finally with a vinyl-terminated poly(amino-amide). The latter involves the use of poly(1-acryloylbenzotriazole) in an intermediate step. The surfaces of the poly(amino-amide) - grafted materials showed a good heparin adsorbing capacity. Most of the adsorbed heparin was released only by elution with aqueous NaOH of pH 〉 10, thus confirming the strong interaction between polymer and heparin.
