Akd emulsion and method of making

Abstract

Provided is an alkyl ketone dimer emulsion and the preparation thereof.

         8 . The composition according to  claim 1 , further comprising a saturated or unsaturated fatty acid. 
     
     
         9 . The composition according to  claim 8 , wherein the fatty acid in the composition is present an amount of from about 0.1 to about 10 wt. %, or about I wt. % to about 10 wt. %, based on the total weight of the composition. 
     
     
         10 . The composition according to  claim 1 , wherein a paper product treated with the composition has higher water resistance compared with an untreated paper product. 
     
     
         11 . A method of preparing an oil in water emulsion, wherein the method comprises:
 providing a composition comprising
 a. a first component chosen from a polydiallyldimethylammonium chloride (polyDADMAC), a polyacrylamide, a polyamine, a polyethyleneimine, a. polyvinyl alcohol, and combinations thereof;
