Polymer latex compound
View Patent ↗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.
1. 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 the latex without said polyacrylonitrile, wherein said wt. % is based on a total weight of said polymer latex composition.
2. The composition of claim 1 , wherein said natural rubber latex is cross-linked using sulfur vulcanization.
3. The composition of claim 1 , further comprising stabilizing agent.
4. The composition of claim 3 , wherein said stabilizing agent is a soap.
5. The composition of claim 3 , further comprising a pH adjuster in an amount suitable to cause the polyacrylonitrile to be alkaline.
6. The composition of claim 1 , further comprising a curing agent.
7. The composition of claim 6 , wherein said curing agent comprises at least one of zinc oxide, sulfur, a cure accelerator, and an antioxidant.
8. The composition of claim 1 , further comprising a coloring agent.
