A grafting reagent and related method of using the reagent to form a polymeric layer on a support surface, and particularly a porous support surface, in a manner that provides and/or preserves desired properties (such as porosity) of the surface. The reagent and method can be used to provide a thin, conformable, uniform, uncrosslinked coating having desired properties onto the surface of a preformed, and particularly a porous, polymeric substrate. The method includes the steps of a) providing a porous support surface, b) providing a nonpolymeric grafting reagent comprising a photoinitator group, c) providing one or more polymerizable monomers adapted to be contacted with the surface, in the presence of the grafting reagent, and to be polymerized upon activation of the photoinitiator; and d) applying the grafting reagent and monomer(s) to the surface in a manner, and under conditions, suitable to coat the surface with the grafting reagent and to cause the polymerization of monomers to the surface upon activation of the grafting reagent.

What is claimed is: 1. A grafting system for use in forming a polymeric coating on a support surface, the system comprising:(a) a nonpolymeric grafting reagent comprising at least one photoinitator group and one or more latent reactive groups, wherein one or more latent reactive groups are adapted to covalently attach the grafting reagent to the surface, and wherein at least one photoinitiator group is selected from:(i) tetrakis(4-benzoylbenzyl ether), the tetrakis(4-benzoylbenzoate ester) of pentaerytluitol, and an acylated derivative of tetraphenylmethane,(ii) 4,5-bis(4-benzoylphenylmethyleneoxy)benzene-1,3-disulfonic acid dipotassium salt (DBDS),2,5-bis(4-benzoylphenylmethyleneoxy)benzene-1,4-disulfonic acid dipotassium salt (DBHQ), and 2,5-bis(4-benzoylphenylmethyleneoxy)benzene-1-sulfonic acid mono (or di-) sodium salt; and(iii) ethylenebis(4-benzoylbenzyldimethylammonium)dibromide (Diphoto-Diquat); hexamethylenebis(4-benzoylbenzyldimethylammonium)dibromide (Diphoto-Diquat); 1,4-bis(4-benzoylbenzyl)-1,4-dimethylpiperazinediium dibromide (Diphoto-Diquat); bis(4-benzoylbenzyl)hexamethylenetetraminediium dibromide (Diphoto-Diquat): bis[2-(4-benzoylbenzyldimethylammonio)ethyl]-4-benzoylbenzylmethylammonium tribromide (Triphoto-Triquat): 4,4-bis(4-benzoylbenzyl)morpholinium bromide (Diphoto-Monoquat); ethylenebis[(2-(4-benzoylbenzyldimethylammonio)ethyl)-4-benzoylbenzylmethylammonium]tetrabromide (Tetraphoto-Tetraquat); 1,1,4,4-tetrakis(4-benzoylbenzyl)piperazinediium Dibromide (Tetraphoto-Diquat); and N,N-bis[2-(4-benzoylbenzyloxy)ethyl]-2-aminoethanesulfonic acid, sodium salt (Diphoto-Monosulfonate), and analogues thereof; and(b) at least one polymerizable molecule solution, wherein the solution is polymerized upon activation of at least one photoinitiator group provided by the reagent.
