Abstract
Aromatic polymer materials, such as polyethersulphone, polysulphone or polycarbonates in granular or porous forms with a solvent such as acetone or butanone. The resultant mixture is thereafter compressed and compounded to significantly increase its density producing a pre-form substantially free of large irregular voids. The preform is then capable of being formed in a foamed structure under heat.
