摘要

The invention relates to polyelectrolytes and their use in the fractionation of blood and other proteinaceous substances. …The filterability, drying characteristics and physical form of water-insoluble, cross-linked polyelectrolytes containing amine-imide functional groups are employed without substantially diminishing the protein adsoprtion capacity of said polyelectrolytes by heating the polymeric starting material in inert organic solvent at a temperature ranging from about 115 DEG C to about 160 DEG C but lower than the softening point of said polymer for at least about 15 minutes and until said polymer is substantially aggregated prior to crosslinking.
