That which is claimed is: 1. A method of manufacturing an antifungal acrylic polymer composition comprising: combining a quantity of an antifungal agent and an acrylic precursor solution; and polymerizing the precursor solution to form an acrylic polymer composition; wherein the weight concentration of antifungal agent in the polymer composition is in a range from about 250 ppm to about 50,000 ppm based upon the weight of the polymer composition; and wherein the antifungal agent is selected from the group consisting of isothiazoline, an oxathiazine, an azole, and a mixture thereof. 2. The method according to claim 1, wherein the antifungal agent is an isothiazoline selected from the group consisting of 2-n-octyl-4-isothiazolin-3-one and N-butyl-1,2 benzisothiazolin-3-one. 3. The method according to claim 1, wherein the oxathiazine is bethoxazin. 4. The method according to claim 1, wherein the antifungal agent is an azole selected from the group consisting of propiconazole, tebuconazole, and a mixture thereof. 5. The method according to claim 1, further comprising forming the antifungal acrylic polymer composition into a thermoformable sheet. 6. The method according to claim 1, wherein the antifungal agent is present in an amount from about 500 ppm to about 10,000 ppm. 7. The method according to claim 5, further comprising molding the thermoformable acrylic sheet into a product. 8. The method according to claim 7, wherein the product is selected from the group consisting of windshields, skylights, outdoor signs, boat surfaces, automobile tail lights, display cases, light fixtures, shower stalls, spas, bathroom basins, and counter tops, hot tubs, shelving, decorative laminates and other structural items.
