Abstract
A coating composition comprises an aqueous solution comprising at least one vinyl carboxylic acid monomer and at least one neutral monomer, wherein the at least one neutral monomer has a glass transition temperature of less than about 100° C. in homopolymeric form. A device comprises a protonated polyacrylate coating, wherein the device is inherently antimicrobial, anti-thrombogenic, flexible, and/or sheds few to no particulates.
Claims13
A polymeric coating comprising a copolymer graft-polymerized onto the surface of a medical device from at least one water soluble vinyl carboxylic acid monomer and at least one water soluble neutral monomer, wherein the at least one water soluble neutral monomer has a glass transition temperature of less than about 100° C. in homopolymeric form, and wherein the vinyl carboxylic acid monomer in the graft-polymerized copolymer is protonated.
