zed polyolefin are melt-kneaded in an extruder along with water and a neutralizing agent, such as ammonia, potassium hydroxide, or a combination of the two, to form an aqueous dispersion.Mechanical dispersion, such as a Parr reactor, is used to create the aqueous dispersion.In one embodiment, the metallocene catalyzed polyolefin comprises at least one of ethylene/octene copolymers, ethylene/butene
