Polyvinyl chloride glove having improved chemical resistance

Abstract

A glove having improved chemical permeation resistance includes a substrate body formed from polyvinyl chloride and a barrier layer overlying at least a portion of the substrate body, where the barrier layer is formed from an acrylic polymer having a glass transition temperature of from about −30° C. to about 30° C.

1 . A glove having improved chemical permeation resistance comprising: 
 a substrate body comprising polyvinyl chloride; and    a barrier layer overlying at least a portion of the substrate body, the barrier layer comprising an acrylic polymer having a glass transition temperature of from about −30° C. to about 30° C.    
   
   
       2 . The glove of  claim 1 , wherein the barrier layer is present in an amount of from about 3 mass % to about 8 mass % of the glove.  
   
   
       3 . The glove of  claim 1 , wherein the barrier layer is present in an amount of from about 4 mass % to about 6 mass % of the glove.  
   
   
       4 . The glove of  claim 1 , wherein the barrier layer is a skin-contacting layer.  
   
   
       5 . The glove of  claim 1 , wherein the barrier layer is visually distinct from the substrate body.  
   
   
       6 . The glove of  claim 1 , further comprising a donning layer overlying at least a portion of the barrier layer, wherein the donning layer is a skin-contacting layer.  
   
   
       7 . The glove of  claim 6 , wherein the donning layer comprises a polyurethane.  
   
   
       8 . The glove of  claim 6 , wherein the donning layer is present in an amount of from about 0.1 mass % to about 2 mass % of the glove.  
   
   
       9 . The glove of  claim 6 , wherein the donning layer is present in an amount of from about 0.3 mass % to about 1 mass % of the glove.  
   
   
       10 . A glove having improved chemical permeation resistance comprising: 
 a substrate body comprising polyvinyl chloride;    a barrier layer overlying at least a portion of the substrate body, the barrier layer comprising an acrylic polymer; and    a donning layer overlying at least a portion of the barrier layer, the donning layer comprising a polyurethane.    
   
   
       11 . The glove of  claim 10 , wherein the acrylic polymer has a glass transition temperature of from about −30° C. to about 30° C.  
   
   
       12 . The glove of  claim 10 , wherein the acrylic polymer has a glass transition temperature of from about −20° C. to about 20° C.  
   
   
       13 . The glove of  claim 10 , wherein the acrylic polymer has a glass transition temperature of from about −10° C. to about 10° C.  
   
   
       14 . The glove of  claim 10 , wherein the glove is resistant to 70% isopropyl alcohol for at least 90 minutes using ASTM F739-99a.  
   
   
       15 . The glove of  claim 10 , wherein the glove is resistant to 70% isopropyl alcohol for at least 100 minutes using ASTM F739-99a.  
   
   
       16 . The glove of  claim 10 , wherein the glove is resistant to 70% isopropyl alcohol for at least 110 minutes using ASTM F739-99a.  
   
   
       17 . The glove of  claim 10 , wherein the glove is resistant to 70% isopropyl alcohol for at least 120 minutes using ASTM F739-99a.  
   
   
       18 . A method of forming a glove having improved chemical permeation resistance comprising: 
 preparing a substrate body from a polyvinyl chloride plastisol; and    forming a barrier layer over at least a portion of the substrate body, the barrier layer being formed from a barrier layer composition comprising an acrylic emulsion.    
   
   
       19 . The method of  claim 18 , further comprising forming a donning layer over at least a portion of the barrier layer.  
   
   
       20 . The method of  claim 18 , further comprising rendering the barrier layer visually distinct from the substrate body.  
   
   
       21 . The method of  claim 19 , wherein the step of rendering the barrier layer visually distinct from the substrate body comprises adding a colorant to the barrier layer composition.
