Abstract

A polymer latex composition has an acrylonitrile component, a polychloroprene component, and a natural latex component. When these components are blended together and formed into a film, the film exhibits a resistance to ozone that is greater than a resistance to ozone of materials in which acrylonitrile is not included. Furthermore, the combination of acrylonitrile and chloroprene imparts a synergistic effect to the composition with regard to ozone resistance. The film can be formed into a glove having a resistance to ozone that is improved over the resistance to ozone of gloves not including acrylonitrile. The glove may include an antimicrobial agent.

Claims (12)

1. A glove fabricated from a polymer latex composition comprising:

about 18 wt. % to about 22 wt. % polyacrylonitrile;

about 18 wt. % to about 22 wt. % polychloroprene; and

about 56 wt. % to about 64 wt. % natural rubber latex;

wherein said polyacrylonitrile, polychloroprene and natural rubber latex are blended together and formable into a film having a resistance to ozone that is greater than a resistance to ozone of a composition without said polyacrylonitrile;

wherein said film is formed into the shape of the glove; and

wherein said wt. % is based on a total weight of said polymer latex composition.

2. The glove of claim 1 , wherein said film is formed into the shape of the glove by a casting process.

3. The glove of claim 1 , further comprising about 3 wt. % to about 7 wt. % of a stabilizing agent.

4. The glove of claim 1 , further comprising an antimicrobial agent.

5. The glove of claim 4 , wherein said antimicrobial agent is diiodomethyl-p-tolylsuflone.

6. The glove of claim 4 , wherein said antimicrobial agent is selected from the group consisting of triclosan, fluorescent material, silver salt, biguanide, chlorohexidene salt, dextran sulfate, quaternary ammonium salt, benzalkonium, acriflavine, acridine dye, gentian violet, mercurochrome, extract of blue green algae, and mixtures thereof.
