Abstract: A process for producing porous polymer material. The method combines a polymer and water-soluble granules to form a mixture. The mixture is placed into a mold; the surface of the polymer is dissolved to cause cohesion and form a polymer structure having water-soluble granules dispersed within, and water is introduced into the inner part of the polymer structure so that the polymer is solidified and water-soluble granules are washed out to obtain a porous polymer material. According to the invention, single or multiple layers of porous polymer material with different apertures, porosities, or made with different materials, are obtained by combining different polymer materials and water-soluble granules having different particle sizes in different weight ratios.

Abstract: A method of efficiently removing a low molecular weight substance from a polyimide precursor or polyimide in which the low molecular weight substance is dispersed as micro-domains, without using a large amount of an organic solvent. The method of removing a low molecular weight substance comprises subjecting either a polymer composition having a micro-domain structure made up of a continuous phase comprising a polyimide precursor and, dispersed therein, a discontinuous phase comprising a low molecular weight substance or a polyimide composition obtained from the polymer composition by converting the polyimide precursor into a polyimide to extraction with a combination of supercritical carbon dioxide and a co-solvent to thereby remove the low molecular weight substance. The co-solvent is preferably an aprotic polar solvent, more preferably a nitrogen compound solvent or a sulfur compound solvent.

Abstract: A composition has a polymeric network that includes a porogen and a photoinitiator. The photoinitiator produces a reactive species upon irradiation, which reacts with the porogen in a degradation reaction that degrades at least some of the porogen. A method of forming a nanoporous polymer has one step in which a plurality of polymeric strands, a photoinitiator, and a porogen are provided. In a subsequent step, at least some of the polymeric strands are crosslinked to form a polymeric network that includes the porogen and the photoinitiator, and in a further step the photoinitiator in the polymeric network is irradiated to generate a reactive species that reacts with the porogen in a degradation reaction to degrade at least some of the porogen.

Abstract: Highly uniform microporous foam suitable for medical applications and methods for preparing these foams. The highly uniform microporous foams are of controlled pore size that may be utilized in a variety of applications. In preparing the foams, an organic crystalline polymer is melted and combined with a selected solid crystalline fugitive compound to produce a substantially isotropic solution. The solution is cooled under controlled conditions, which foster solid-solid phase separation by the simultaneous crystallization of the fugitive compound and the polymer, to produce a foam precursor containing the solidified fugitive compound dispersed through a matrix of the organic polymer. Crystals of fugitive compound are then removed by solvent extraction and/or sublimation, or like process to produce microcellular foams having a continuous, open-cell structure.

Abstract: A microcellular low density foam of poly(4-methyl-1-pentene) which is particularly useful for forming targets for inertial confinement fusion has been developed. Articles made from the foam have been machined to tolerances of 0.0001 inch, although the densities of the fragile foam are low (about 10 to about 100 mg/cc) and the cell sizes are small (about 10 to about 30 .mu.m). Methods for forming the foam and articles are given; and the yield strength of the foam of the invention is higher than was obtained in other structures of this same material.
