Abstract:
A solid support having a coating on its surface which alters the properties of the support surface for separating components in a fluid stream in contact therewith, said coating comprising(a) coupling agent including carbon chains and a functional group and being covalently bound in a layer to said support surface, and(b) preformed polymer comprising totally saturated, substituted or unsubstituted, carbon chain backbones from which leaving groups have been abstracted while in solution in contact with said coupling agent layer to form free radical carbon bonding sites on said preformed polymer which covalently bind to said coupling agent through carbon-to-carbon linkages and to cross link said preformed polymer forming a coating comprising a three-dimensional, cross-linked polymer network on said solid support, said solid support comprising the packing of a flowthrough particle bed.
