Abstract: A method of producing porous polyimide resin that enables pores to be formed in a precursor of polyimide resin, with its form of microphase-separated structure wherein a dispersive compound is dispersed in the precursor of polyimide resin being kept unchanged, so as to provide significantly reduced dielectric constant and also provide improvement in mechanical strength and heat resistance, and the porous polyimide resin produced in the same producing method. A coating comprising porous polyimide resin is formed by applying resin solution comprising a precursor of polyimide resin and a dispersive compound and then drying a solvent, to form a coating in which the dispersive compound is dispersed in the precursor of polyimide resin; extracting the dispersive compound from the coating for removal to make the precursor of the polyimide resin porous; and imidizing the coating after preheated in a temperature range of 190-250null C.

Abstract: The video attachment is an apparatus to be mounted laterally on a microscope and which is independent of the optic of the microscope. The apparatus comprises an imaging lens system and a video camera. The light beam path in the apparatus is deflected in such a manner that the video camera does not impede the use of the microscope. The video attachment is preferably used with a microscope of a slit lamp for the diagnosis of the eye.

Abstract: A novel microporous isocyanate-based xerogel composition is disclosed. The composition can be prepared by a method comprising (1) (1) admixing (a) a polyisocyanate component, (b) a substantially unreactive solvent, and, optionally, (c) a polymerization catalyst, water, an active-hydrogen compound or a mixture thereof, provided that (c) is included wherein (b) does not also function to catalyze polymerization; under reaction conditions sufficient to form a gel; and (2) removing the solvent under non-supercritical conditions sufficient to form a microporous xerogel composition. The compositions can be readily evacuated for use in thermal insulative applications such as vacuum panels, for uses such as appliance insulation, which show superior K-factor values when compared with, for example, conventional rigid polyurethane open-cell foams as used in similar applications.

Abstract: The invention relates to polyolefin foams consisting of polyolefins of ultrahigh molecular weight, i.e. weight-average molecular weight from about 4.times.10.sup.5 to 6.times.10.sup.6 g/mol and higher, and to a novel process for producing these foams by foaming a solution of a polyolefin of ultrahigh molecular weight in a solvent with the use of a physical or chemical blowing agent or of an inert gas blown into the solution, and cooling of the resulting foam to a temperature below the gelling temperature of the polyolefin. If appropriate, these foams can be provided wholly or partially with a smooth skin on their surface by superficial cooling, if appropriate under the action of pressure. These foams are distinguished by high tensile strength and impact strength values, shock-absorbing properties, low glass transition temperatures, low embrittlement at low temperatures and high chemical resistance, and they are used especially as mechanical and acoustic insulating materials, materials of construction, filter agents and implantation materials.
