  • Patent number: 9777116
    Abstract: Methods of forming nanoporous materials are described herein that include forming a polymer network with a chemically removable portion. The chemically removable portion may be polycarbonate polymer that is removable on application of heat or exposure to a base, or a polyhexahydrotriazine (PHT) or polyhemiaminal (PHA) polymer that is removable on exposure to an acid. The method generally includes forming a reaction mixture comprising a formaldehyde, a solvent, a primary aromatic diamine, and a diamine having a primary amino group and a secondary amino group, the secondary amino group having a base-reactive substituent, and heating the reaction mixture to a temperature of between about 50 deg C. and about 150 deg C. to form a polymer. Removing any portion of the polymer results in formation of nanoscopic pores as polymer chains are decomposed, leaving pores in the polymer matrix.

  • Patent number: 8318826
    Abstract: Polyether polyols are initiated with orthocyclohexanediamines such as 1,2-diaminocyclohexane. The polyols are useful in making rigid polyurethane foams, especially foams for pour-in-place applications, where they give a good combination of low k-factor and short demold times.

  • Patent number: 8304467
    Abstract: A polishing pad generates very few scratches on a surface of a polishing object, and is excellent in planarization property. The polishing pad has a high polishing rate and is excellent in planarization property. The polishing pad grooves become very little clogged with abrasive grains or polishing swarf during polishing and, even when continuously used for a long period of time, the polishing rate is scarcely reduced.

  • Publication number: 20120219780
    Abstract: A soft and resilient, cold-water dispersible polyurethane foam suitable for disposable personal care products is produced by the combination of corn syrup, glycerin, polyether diamine, PEG, a diisocyanate, water and a catalyst. The formulation and reaction conditions for forming the inventive foam are judiciously selected and carefully controlled to achieve water dispersibility and the desired mechanical properties. The characteristic resiliency, or percent rebound for the foams was generally over 75% and the foams are readily produced as soft foams, exhibiting a relative compression value of from 20% to 150% of that of a commercial polyurethane foam cosmetic pad which is not water dispersible. The foam may be incorporated into webs or stackable products or nestable three-dimensional products.

  • Publication number: 20120152846
    Abstract: Porous three-dimensional networks of polyurea and porous three-dimensional networks of carbon and methods of their manufacture are described. In an example, polyurea aerogels are prepared by mixing an triisocyanate with water and a triethylamine to form a sol-gel material and supercritically drying the sol-gel material to form the polyurea aerogel. Subjecting the polyurea aerogel to a step of pyrolysis may result in a three dimensional network having a carbon skeleton, yielding a carbon aerogel. The density and morphology of polyurea aerogels can be controlled by varying the amount of isocyanate monomer in the initial reaction mixture. A lower density in the aerogel gives rise to a fibrous morphology, whereas a greater density in the aerogel results in a particulate morphology. Polyurea aerogels described herein may also exhibit a reduced flammability.
