Abstract
Filler particles useful for filling organic resins such as polyethylene are produced by mixing a filler, such as calcium carbonate, with a halogenated polar polymer such as a halogenated ethylene/acrylic acid copolymer. The fillers of the invention impart improved physical properties such as tensile, flexural and impact strength to organic resins.
