Conclusions
The selective properties of hollow fibres used in the separation of solutions of poly-ethylene glycols and proteins have been investigated. It has been shown that the increase in retention coefficient and specific permeability as the velocity of the stream increases, in the separation of solutions of kinetically relatively flexible polyethylene glycol molecules, is not connected with the phenomenon of concentration polarization. but can be explained by the deformability of the tangles of polyethylene glycol macromolecules on flow of the solution in thin capillaries (hollow fibres).
Optimum ultrafiltration conditions have been determined.
Complete retention curves have been constructed for the hollow fibre, which make it possible to determine its region of use.
