Abstract
This invention relates to improved porous solid supports for chromatography and catalysis. The supports are prepared by covalently binding a tether polymer to a solid support, and then blocking the remainder of the support surface with a blocking reagent. The tethered polymer ligands are then covalently bound to the support by graft polymerization reactions.
Claims32
A solid support comprising (i) a solid noncompressible material, and (ii) a tether polymer covalently bound to the solid that is amenable to grafting with other polymers, and (iii) a protective polymeric surface covering that reduces nonspecific interactions of solutes with said solid, and (iv) a functional polymer or copolymer grafted to the tether polymer and possessing useful chemical functionality.
