Antimicrobial-coated medical articles

An article comprising:

• a coating composition comprising a vinyl polymer having a plurality of pendant groups comprising
• a first pendant group comprising a cationic component selected from the group consisting of a quaternary amine component, protonated tertiary amine component, and a protonated secondary amine component;
• a second pendant group comprising a nonpolar component wherein the second pendant group is selected from the group consisting of linear or branched alkanes, alkaryl, aralkyl, aromatic groups, and combinations thereof;
• and
• a third pendant group comprising a first organosilicon component;
• wherein the vinyl polymer does not comprise a pendant group that comprises a carboxylate group;
• and
• an elastomeric body fluid-contacting first substrate having a body fluid-contacting first surface and a second surface;
• wherein the vinyl polymer is durably adhered to the body fluid-contacting first surface, and
• wherein the composition is free of inorganic filler.

A method of making a coated article, the method comprising:

• forming a first coating composition comprising a vinyl polymer having a plurality of pendant groups comprising
• a first pendant group comprising a first cationic component selected from the group consisting of a quaternary amine component, protonated tertiary amine component, and a protonated secondary amine component;
• a second pendant group comprising a nonpolar component wherein the second pendant group is selected from the group consisting of linear or branched alkanes, alkaryl, aralkyl, aromatic groups, and combinations thereof;
• and
• a third pendant group comprising a first organosilicon component;
• wherein the vinyl polymer does not comprise a pendant group that comprises a carboxylate group;
• and
• wherein the first coating composition is free of inorganic filler;
• and
• contacting the first coating composition with a first surface of a first substrate to adhere the vinyl polymer to the first surface;
• wherein the first substrate comprises an elastomeric component of a medical device or an elastomeric body fluid-contacting substrate.

A medical device article comprising a coating wherein the coating is derived from:

• a composition comprising a free silane component and a vinyl polymer having a plurality of pendant groups comprising
• a first pendant group comprising a first quaternary ammonium component;
• a second pendant group comprising a nonpolar component wherein the second pendant group is selected from the group consisting of linear or branched alkanes, alkaryl, aralkyl, aromatic groups, and combinations thereof;
• and
• a third pendant group comprising a first organosilicon component;
• wherein the vinyl polymer does not comprise a pendant group that comprises a carboxylate group;
• wherein the vinyl polymer is durably adhered to a surface of the article;
• and
• wherein the composition is free of inorganic filler.
