1 . A composition comprising: 
 a polyalphaolefin polymer; and    from about 20% by weight to about 70% by weight adsorbent, said composition being essentially free of a film forming agent.    
     
     
         2 . The composition of  claim 1 , wherein said polyalphaolefin polymer comprises a polymer comprising monomers selected from the group consisting of ethylene, propylene, butene, pentene, hexene, octene, decene, isoprene, terpene, vinyl acetate, styrene, butadiene, and combinations thereof.  
     
     
         3 . The composition of  claim 1 , wherein said composition exhibits a melt flow time of no greater than 60 seconds at 190° C.  
     
     
         4 . The composition of  claim 1 , wherein said composition exhibits a melt flow time of no greater than 15 seconds at 190° C.  
     
     
         5 . The composition of  claim 1 , wherein said composition exhibits a melt flow time of less than 5 seconds at 190° C.  
     
     
         6 . The composition of  claim 1 , wherein said composition comprises from about 40% by weight to about 70% by weight adsorbent.  
     
     
         7 . The composition of  claim 1 , wherein said adsorbent comprises an adsorbent capable of adsorbing organic species.  
     
     
         8 . The composition of  claim 1 , wherein said composition, when applied to a substrate and subjected to 88° C. for one month, is essentially free from sag.  
     
     
         9 . The composition of  claim 1 , wherein said composition passes the ASTM E1887 fog test.  
     
     
         10 . An insulating glass assembly comprising: 
 a first glass substrate;    a second glass substrate;    a separator disposed between said first glass substrate and said second glass substrate; and    the composition of  claim 1  in contact with said separator.    
     
     
         11 . The assembly of  claim 10 , wherein said composition exhibits a melt flow time of less than 5 seconds at 190° C.  
     
     
         12 . A composition consisting essentially of: 
 a polyalphaolefin polymer;    from about 20 to about 70% by weight of an adsorbent selected from the group consisting of moisture adsorbents, volatile organic adsorbents, and combinations thereof;    from 0 to 10% by weight tackifying resin; and    from 0 to 5% by weight antioxidant.    
     
     
         13 . The composition of  claim 12  consisting essentially of said polyalphaolefin polymer and said adsorbent.
