Abstract
The preparation of compression moulded films of nanocomposites of poly(methyl methacrylate) with various proportions of organoclay by dry-blend and solvent co-precipitation methods, and their characterisation by SEM and SAXS, is described. The solubility and diffusivity of carbon dioxide in the nanocomposites was investigated using gravimetry and high-pressure DSC, and the effects of organoclay content and dispersion on cellular morphology of the resulting nanocomposite foams are discussed. 40 refs.

Abstract
The development of a process for the fabrication of microcellular panels using a constrained solid-state foaming process with carbon dioxide gas, based on a systematic study of process variables, is presented. The production of microcellular panels from poly(methyl methacrylate), polystyrene and acrylonitrile-butadiene-styrene terpolymers, and their characterisation by thickness, microstructure (SEM) and density, is described. 20 refs.

Abstract
The effects of controlling the foaming temperature on the cell size and cell density of microcellular poly(methyl methacrylate) were investigated by SEM using the batch foaming process with carbon dioxide gas as blowing agent. The results are discussed in terms of cell structures obtained using elevated temperature and constant temperature processing methods. 16 refs.
