Abstract: Mesoporous poly (aryl ether ketone) articles are formed from blends of poly (aryl ether ketones) with pore forming additives by melt processing, and can be in the form of a monofilament, disc, film, microcapillary or other complex shapes. The method of formation provides for preparation of poly (aryl ether ketone) articles with high degree of surface area and uniform nanometer pore size. The preferred poly (aryl ether ketone)s are poly (ether ketone) and poly (ether ether ketone). The mesoporous articles formed by the method of the present invention are useful for a broad range of applications, including molecular separations and organic solvent filtration.

Abstract: The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc.

Abstract: High-temperature foams are produced and used in the construction of aeroplanes, ships and rail and other vehicles. In particular, the foams are further processed into sandwich materials by joining with two outer layers. To this end, a novel process is used for producing high-temperature foams (HT foams) which are particularly suitable for producing such sandwich components for lightweight construction. This process achieves an improvement in the processability of the HT foams produced and a weight reduction of the sandwich materials. The HT foams are furthermore rigid particle foams which are markedly more economic to produce than rigid block foams. In particular, a reduction is brought about in resin absorption in fibre composite processes through a process-related optimization of the surface constitution.
