Dialysis membranes and manufacture |
| abstract |
Non-thrombogenic hemodialysis flat membranes useful in artificial kidneys are prepared from quaternized membranes of polymers made from monomeric substances of which at least a sufficient amount of a vinylpyridine is included to provide membranes which on heparinization are non-thrombogenic particularly polymers made from monomeric substances of which from 2 to 10 percent by weight of the total monomer is a vinylpyridine and at least 80 percent by weight is acrylonitrile. Both copolymers and blends of polymers can be used. A novel process is described for making the quaternized membranes. |
