    摘要: A prosthetic polymer material is made non-thrombogenic by immobilizing apyrase on its surface. Immobilization is preferably carried out by hydrolytically activating the surface of a polyamide polymer or a polyethylene terphthalate polymer, and treating the hydrolyzed polymer with a solution of cross-linking agent and a solution of apyrase. The apyrase converts adenosine diphosphate to adenosine monophosphate and adenosine whereby the formation of thrombi is inhibited.

    摘要: An asymmetrical membrane for use in dialysis and ultra-filtration is prepared using a polyester-amide (TATE).sub.n, wherein T represents a radical of terephthalic acid, A represents a radical of hexamethylenediamine, and E represents a radical of hexanediol, in a solvent of formic acid or in a solvent comprising a solution of lithium chloride in dimethylformamide or dimethylacetamide. The polyester-amide (TATE).sub.n is formed into a thin layer and placed into an aqueous coagulation bath to coagulate the resulting membrane. The membrane has a thickness of from 15 to 190 .mu.m, a water permeability of from about 3 up to about 9 liters/m.sup.2 /hour for a .DELTA.P of 300 mm.sub.HG and is permeable for substances having a molecular weight of up to about 17,000.

    摘要: A hollow fibre of polyester-amide, useful in the process of dialysis and in ultra-filtration processes in general, is formed by a polyester-amide with repetitive units (TATE).sub.n (wherein T is the terephthalic acid radical; A is the ethylenediamine radical; and E is the hexanediol radical).Such a fibre is obtained by a process which comprises the following steps, carried out sequentially:preparation of a solution of polyesteramide (TATE).sub.n in a solvent constituted by formic acid at a concentration higher than about 99%, or constituted by a solution of lithium chloride in dimethylformamide or dimethylacetamide;extrusion of said solution through a spinnerette having a cross section of annular shape and coagulation of the fibre in an aqueous coagulation bath, with the possible introduction of an aqueous coagulating liquid to the interior of the annular opening of the spinnerette;washing with water and recovery of the so-obtained hollow fibre.
