Claims35
An antimicrobial composition comprising:
- a polymerizable mixture comprising:
- at least one high Tg monomer and optionally a homopolymer thereof, wherein the homopolymer has a Tg of between about 40° C. and about 250° C.;
- and
- at least one low Tg monomer and optionally a homopolymer thereof, wherein the homopolymer has a Tg of between about −70° C. and about 30° C.;
- wherein upon polymerization, the polymerizable mixture forms a water-insoluble polymer composition comprising a copolymer derived from the at least one high Tg monomer and the at least one low Tg monomer;
- an organic acid chelator, salt thereof, or combination thereof having a molecular weight less than about 400 g/mol;
- and
- a water-soluble plasticizer capable of solubilizing the organic acid chelator, or salt thereof, in an amount of at least about 100 g chelator per L of plasticizer at a temperature from about 20° C. to about 23° C.
