Abstract: A porous polymer blend, and a method of producing a porous polymer blend from at least two immiscible polymers. The at least two immiscible polymer being blended together and exhibiting the absence of complete phase separation. The method of producing a porous polymer blend comprising: forming a liquid composition comprising at least two immiscible polymers dissolved in a common solvent; subjecting the liquid composition to a reduction in temperature to cause at least two immiscible polymers to phase separate into a common polymer rich phase and a common polymer poor phase; solidifying the at least two immiscible polymers in the common polymer rich phase so as to avoid complete phase separation of the at least two immiscible polymers; and removing the common polymer pore phase to provide a blend of the at least two immiscible polymers having a porous morphology.

Abstract: A process for producing porous polymer beads in which polymers, preferably polyolefins or polyvinyl chloride, are dissolved in a solvent, preferably halogenated hydrocarbons or alkyl esters, at temperatures close to the boiling point of the solvent. The hot polymer solution is cooled, and the polymer beads formed during the cooling process are separated, washed and dried.

Abstract: An improved method is taught for preparing porous structures from olefin polymers by heating a dispersion of such polymers in a hydrocarbon liquid to a temperature above the solution temperature, cooling slowly to form a gel and extracting the hydrocarbon liquid. The improvement resides in employing, as a starting material a polymer in the form of particles no larger than about 0.5 Mu .

Abstract: A polymer matrix composite comprising a porous polymeric network; and a plurality of dielectric particles distributed within the polymeric network structure; wherein the dielectric particles are present in a range from 5 to 98 weight percent, based on the total weight of the dielectric particles and the polymer (excluding the solvent); and wherein the polymer matrix composite has a dielectric constant in a range from 1.05 to 80; and methods for making the same. Polymer matrix composites comprising dielectric particles are useful, for example, as electric field insulators.

Abstract: A porous material includes a polyhexahydrotriazine material. Pores in the porous material can be of various sizes including nanoscale sizes. The porous material may be used in a variety of applications, such as those requiring materials with a high strength-to-weight ratio. The porous material can include a filler material dispersed therein. The filler material can be, for example, a particle, a fiber, a fabric, or the like. In some examples, the filler material can be a carbon fiber or a carbon nanotube. A method of making a porous material includes forming a resin including a polyhemiaminal or polyhexahydrotriazine component and a polythioaminal component. The resin can be heated to promote segregation of the components into different phases with predominately one or the other component in each phase. Processing of the resin after phase segregation to decompose the polythioaminal component can form pores in the resin.
