    Abstract: Crosslinked organic polymeric porous particles have a crosslinked organic solid phase and discrete pores dispersed within the crosslinked solid phase which pores are isolated from each other. These porous particles are prepared using one or more water-in-oil emulsions containing a polyfunctional reactive compound, a reagent that causes crosslinking, optionally an ethylenically unsaturated polymerizable monomer, and optionally an organic solvent, and can include various marker materials.

The dried porous crumbs have a water content of 1% by weight or less and having the capability of absorbing an oil in an amount of 1.0 or more, in terms of the ratio of the weight of an oil, which is absorbed by the dried porous crumbs when the dried porous crumbs are immersed in the oil at 25° C. under atmospheric pressure for 1 minute, to the weight of the dried porous crumbs. Also disclosed is a method for producing the same. When the dried porous crumbs are used as a modifier in the production of a molding resin composition from a thermoplastic resin and a liquid additive, such as a softening agent or a silicone oil, a shaped article having an excellent appearance can be produced by molding the molding resin composition.

    Abstract: Synthetic methods for the preparation of hydrophobic organics aerogels. One method involves the sol-gel polymerization of 1,3-dimethoxybenzene or 1,3,5-trimethoxybenzene with formaldehyde in non-aqueous solvents. Using a procedure analogous to the preparation of resorcinol-formaldehyde (RF) aerogels, this approach generates wet gels that can be dried using either supercritical solvent extraction to generate the new organic aerogels or air dried to produce an xerogel. Other methods involve the sol-gel polymerization of 1,3,5 trihydroxy benzene (phloroglucinol) or 1,3 dihydroxy benzene (resorcinol) and various aldehydes in non-aqueous solvents. These methods use a procedure analogous to the one-step base and two-step base/acid catalyzed polycondensation of phloroglucinol and formaldehyde, but the base catalyst used is triethylamine. These methods can be applied to a variety of other sol-gel precursors and solvent systems. These hydrophobic organics aerogels have numerous application potentials in the field of material absorbers and water-proof insulation.

    Abstract: A microporous, polymeric film is prepared by dissolving methylene-chloride-soluble, film-forming polymers completely in methylene chloride. Then an aqueous phase is prepared containing non-methylene-chloride-soluble, water-soluble thickeners and, if desired, additives, and brought to a viscosity of about 0.07 to 0.5 Pa s. The aqueous phase is then dispersed in the polymer solution and the resultant paste is spread onto a support material or intermediate support, the methylene chloride is evaporated, the resultant membrane is transferred to the actual support, and finally the water is removed by drying.

    Abstract: AN AQUEOUS LATEX COATING COMPOSITION ADAPTED TO DEPOSIT FILMS WHICH DRY TO FORM A CELLULAR LAYER OF HIGH OPACITY IS PROVIDED BY SWELLING THE RESIN PARTICULES OF THE AQUEOUS LATEX WITH A PRIMARY ORGANIC SOLVENT WHICH IS ESSENTIALLY IMMISICIBLE IN THE AQUEOUS PHASE OF THE LATEX SUCH AS XYLENE, AND BY INTRODUCING INTO THE AQUEOUS PHASE AN AT LEAST PARTIALLY WATER MISCIBLE ORGANIC SOLVENT, SUCH AS PROPYLENE GLYCOL, HAVING A LOWER EVAPORATION RATE AND A LESSER CAPACITY FOR SOLVATING THE RESIN OF THE LATEX THAN SAID PRIMARY SOLVENT. WHEN THE PRIMARY SOLVENT EVAPORATES, A CELLULAR FILM IS FORMED, THE SECONDARY SOLVENT SERVING TO INCREASE THE OPACIFICATION WHICH IS OBTAINED. PARTICULATE MATTER OR MATERIAL WHICH CRYSTALLIZES TO FORM PARTICULATE MATTER IS INCORPORATED INTO THE LATEX IN SMALL AMOUNT. THE PARTICULATE MATTER SERVES TO INCREASE ULTIMATE OPACITY AND ALSO TO GENERATE OPACITY MORE RAPIDLY WHEN A DEPOSITED FILM IS DRIED.
