Ion-exchanged zeolites, such as the zinc ion-exchanged zeolite can also be used. Zeolites are especially useful in lead-free Low Smoke PVC compositions.

  • Publication number: 20040048959
    Abstract: The present invention is directed to a water-based acrylic emulsion dispersant to be used as a grind resin to incorporate inorganic pigment into a pigment dispersion for a coating composition. The acrylic emulsion dispersant is the reaction product of butyl methacrylate, butyl acrylate, styrene, methyl ether polyethylene glycol methacrylate, polyethylene glycol methacrylate, and polyphosphoric acid. The present invention is also directed to a method of preparing the acrylic emulsion dispersant. In this method, the butyl methacrylate, butyl acrylate, and styrene are combined with water to establish a first reaction blend. Similarly, the methyl ether polyethylene glycol methacrylate and the polyethylene glycol methacrylate are combined with water to establish a second reaction blend. Next, the first and second reaction blends are polymerized to form an intermediate emulsion polymer containing a hydroxyl group from the functionality of the polyethylene glycol methacrylate.
