         26 - 37 . (canceled) 
     
     
         38 . The method of  claim 25 , wherein the cellulose composition is dried prior to the combining step. 
     
     
         39 - 44 . (canceled) 
     
     
         45 . The method of  claim 25 , further comprising combining a clay. 
     
     
         46 - 51 . (canceled) 
     
     
         52 . A masterbatch composition prepared by the method of  claim 25 . 
     
     
         53 . A method for making a composition, the method comprising the step of combining:
 (a) a polymer in an amount of from about 60 wt % to about 90 wt % of the composition;   (b) a cellulose composition comprising particles, wherein the particles comprises cellulose, and wherein the cellulose is present in an amount of from about 0.01 wt % to about 5 wt % of the composition; and   (c) a reinforcing filler in an amount of from about 5 wt % to about 50 wt % of the composition.   
     
     
         54 - 63 . (canceled) 
     
     
         64 . The method of  claim 53 , wherein the cellulose composition is a dried cellulose composition. 
     
     
         65 - 67 . (canceled) 
     
     
         68 . The method of  claim 53 , wherein the reinforcing filler is selected from a glass fiber, a mineral filler, and a carbon fiber. 
     
     
         69 - 72 . (canceled) 
     
     
         73 . The method of  claim 53 , further comprises the step of combining a clay. 
     
     
         74 - 77 . (canceled) 
     
     
         78 . The method of  claim 53 , further comprising forming the composition into an article.
