Abstract: An inverted roof membrane assembly (IRMA) includes decking, a waterproofing membrane above the decking, a layer of polymer foam insulation board above the waterproofing membrane, and ballast above the polymer foam insulation board layer. The polymer foam insulation board includes a polymer foam layer that includes an alkenyl aromatic polymer and an infrared radiation attenuator, and first and second facer layers.

Abstract: Composites of macrocyclic oligomers and a filler material are made in a masterbatch process. The masterbatch contains at least 15% by weight of the filler material. The filler material is preferably a submicron sized material and is especially a clay or other layered material that can become at least partially exfoliated. The masterbatch can be let down into more of the macrocyclic oligomer, another polymer, another polymerizable material and subjected to polymerization conditions to form a nanocomposite material. Alternatively, the masterbatch can be polymerized to a high or intermediate molecular weight, and then blended with additional oligomer, polymer or other polymerizable material.

Abstract: The invention relates to polymers derived from macrocyclic oligomers containing organo clay fillers. The invention also relates to processes for preparing such compositions. Furthermore, the invention relates to articles prepared from organoclay filled polymer compositions.
