    Abstract: The invention relates to a method for functionalizing a thermoset, crosslinked isocyanate-based polymeric solid material which is made of isocyanate and isocyanate reactive components, at least one of which comprises an anchor component which has at least one anchor group. The anchor groups on the solid material are formed by terminal alkene and/or alkyne groups. To functionalize this polymeric solid material it is brought in contact with a solution which contains at least one functional component. This functional component comprises at least one thiol group and is allowed to bind covalently to the polymeric solid material by a free-radical addition reaction between the thiol groups on the functional component and the terminal alkene and/or alkyne anchor groups on the undissolved solid material. An effective functionalization of the polymeric material can thus be achieved notwithstanding the heterogeneous reaction conditions.

In addition, the method reduces shrinkage of hydrophobic monolithic silica aerogel, enables production of hydrophobic monolithic silica aerogel in a translucent form, and allows the hydrophobic monolithic silica aerogel to maintain low heat conductivity similar to the heat conductivity of hydrophilic silica aerogel. The hydrophobic monolithic silica aerogel may be used directly as a heat insulating panel by virtue of excellent hydrophobic property and heat insulating property.

The porous beads will be useful in disinfection applications as well as for sanitization and controlling noxious odor when mixed with absorbent materials in items such as disposable diapers, infant swimwear, incontinence pads, bandages, sanitary napkins, pantiliners, mattress covers, shoe inserts, sponges, animal litter, carpets, and fabrics.

  • Publication number: 20110287262
    Abstract: Acid-labile poly(N-vinyl formamide) (“PNVF”) nanocapsules were synthesized by free radical polymerization of N-vinyl formamide with optional active ingredients on the surface of silica nanoparticles. Polymerization in the presence of a novel cross-linker that contains an acid-labile ketal facilitated stable etching of silica nanoparticle templates using sodium hydroxide and recovery of PNVF nanocapsules. The formamido side group of PNVF was then hydrolyzed by extended exposure to sodium hydroxide to produce polyvinylamine (“PVAm”) nanocapsules. PNVF and PVAm nanoparticles are also synthesized that form nanogels with optional active ingredients.

  • Publication number: 20110275727
    Abstract: Disclosed is a resin foam which excels in properties such as strength, flexibility, cushioning properties, and strain recovery, particularly has a cell structure resistant to shrinkage caused by the restoring force of the resin, and has a high expansion ratio. The cross-linked resin foam is obtained by heating a resin composition containing an elastomer, an active-energy-ray-curable compound, and a thermal crosslinking agent to form a cross-linked structure derived from the thermal crosslinking agent in the resin composition; subjecting the cross-linked-structure-containing resin composition to foam molding to give a foamed structure; and irradiating the foamed structure with an active energy ray to form another cross-linked structure derived from the active-energy-ray-curable compound to give the cross-linked resin foam.

  • Patent number: 7993738
    Abstract: Modified porous materials are disclosed having interconnected, complexly shaped three-dimensional surfaces. The modification is accomplished by crosslinking the three-dimensional surfaces or by incorporating, in situ, an inorganic material onto or into three-dimensional surfaces. The porous materials are macro structures including at least one of nano-features, micro-features, and combinations thereof. The modifying accomplishes changing surface properties of the porous materials, changing the three-dimensional surfaces, and/or rendering the porous materials substantially stable in a predetermined environment.

  • Patent number: 7972695
    Abstract: Expandable or pre-expanded thermoplastic particles, e.g. polystyrene particles, used to form foam containers e.g. cups, bowls, are coated with a coating composition comprising a liquid part consisting of a) liquid polyethylene glycol with an average molecular weight of 200 to 800; and a solid part comprising components selected from the group consisting of b) polyolefin wax, e.g. polyethylene wax, c) a metal salt of higher fatty acids, e.g. zinc stearate or calcium stearate; d) polyethylene glycol with an average molecular weight of 900 to 10,000; and e) a fatty bisamide or fatty amide, e.g. ethylene bis-stearamide; and combinations of b) through e). The coating composition prevents or resists leakage of liquids and foods with oil and/or fatty components and improves the rim strength and ATF properties of foam containers.

  • Patent number: 7943676
    Abstract: A method of recycling waste plastic foam materials firstly is to smash a waste material including polyurethane foam into fine particles so as to obtain a first starting material. The first starting material is then crisped and followingly milled into powder so as to obtain a second starting material. The second starting material is then placed into a mixer to mix with a first foaming reaction solution including polyol, catalyst and additives injected into the mixer so as to form a semi-treated foaming material. And then, the semi-treated foaming material is mixed with a second foaming reaction solution including diisocyanate injected into the mixer so as to obtain a completed-treated foaming material. Lastly, the completed-treated foaming material is poured into a mold and then water vapor is uniformly introduced into the mold so as to induce the completed-treated foaming material to proceed foaming reaction.

  • Patent number: 7919541
    Abstract: The present invention concerns a method of manufacturing flame-retardant polyethylene or polypropylene foam using a derivative of carboxylic acid of phenylphosphinic acid and the flame-retardant polymer foam made thereby. More specifically, this invention concerns a method of manufacturing highly expanded flame-retardant polymer foam prepared by mixing the above mentioned phosphorous flame retardant in a polymer resin and expanding the mixture with a volatile blowing agent or by applying a solution of an organic phosphorous compound to an already-made highly expanded foam and then drying the highly-expanded polymer foam, and the flame-retardant foam prepared thereby.
