A blend of a polymer, swelling agent, and a sheet silicate and/or sheet silicone filler is disclosed. The swelling agent makes it possible to intercalate the sheet silicate and/or sheet silicone with a variety of different polymers. The swelling agent is a material with sufficient mobility such that it can enter between the sheets of the silicate or silicone and increase the spacing between sheets. The swelling agent desirably has a solubility parameter that facilitates entry of both the swelling agent and matrix polymer between the layers of the filler promoting intercalation and/or exfoliation.
