  • Patent number: 8511464
    Abstract: Stimuli-responsive highly absorbent superabsorbent polymers (SAPs) are used to harness water to augment water supply and solve water crisis. Rain water is harnessed in fabric-based sachets or bags partially filled with the polymers. The hydrated polymers are used to store water in warehouses for an extended period of time and the invention may obviate the need to construct controversial huge dams and canals or drill wells. The stored water in superabsorbent polymers is released at the point of use by any stimulus which may be light-induced, electrical, thermal or chemical treatment. SAPs with 2000 g/g of absorbency can yield 99.95% pure water in solid/gel form. An ultra SAP with absorbency of 10,000 g/g of the polymer could hold 10 billion cu.m. of water in one million tonnes of the polymer. This is more than the storage capacity of a typical large dam over a river.

  • Publication number: 20120136131
    Abstract: Provided is a method of living radical polymerization which does not necessitate complicated and intricate synthesis of a dormant species and which is highly efficient. A halogenated derivative compound is used as a dormant species for initiating living radical polymerization. The derivative compound is obtained by halogenating an alcohol compound having a non-conjugated structure or an amine compound having a non-conjugated structure with a halogenating agent capable of halogenating an alcohol or amine. A radical produced by elimination of halogen from the halogenated derivative compound is allowed to react with the unsaturated bond of the monomer. Thus, the monomer, which has a radical-reactive unsaturated bond, is polymerized by living radical polymerization. Preferably, the halogenating agent is a compound (NIS or the like) which also has a function as a catalyst.

  • Publication number: 20100016466
    Abstract: The subject matter of the invention is a radically polymerizable dental material comprising at least two components. A first component of the dental material contains the salt of a CH-acidic compound, and an additional component contains an acid with acidity greater than that of the CH-acidic compound of the first component. Both components contain radically polymerizable monomers. When the two components are mixed, the acid of the second component converts the salt of the CH-acidic compound of the first component into a CH-acidic molecule, and the CH-acidic molecule triggers the radical polymerization of the monomers. In addition to the advantages of CH-acidic compounds in dental materials on the basis of a reactive resin, the invention achieves long-term storage stability as a result of an increase in the proportion of the reactive resin matrix in polymerizable dental materials.

  • Patent number: 7244803
    Abstract: A dielectric for aluminum and copper metalizations is stable at high temperatures. Surprisingly, in spite of the elimination of water during the cyclization, the polymeric dielectrics are very suitable for filling narrow trenches. The filled trenches exhibit no defects and bubbles or cracks. The polybenzoxazoles have dielectric constants of k?2.7 and are suitable as an electrical insulator. Furthermore, these materials adhere very well on all surfaces relevant for micro-electronics.

  • Patent number: 6998115
    Abstract: Poly(?-amino esters) prepared from the conjugate addition of bis(secondary amines) or primary amines to a bis(acrylate ester) are described. Methods of preparing these polymers from commercially available starting materials are also provided. These tertiary amine-containing polymers are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the poly(amine) nature of these polymers, they are particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes have been prepared. The inventive polymers may also be used to encapsulate other agents to be delivered. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.

  • Publication number: 20030078328
    Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are extremely low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well.

  • Patent number: 6204354
    Abstract: The instant invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(disubstituted ethylene-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(disubstituted ethylene-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(disubstituted ethylene-co-maleimide) polymer product with an extender oil sufficient to form the gel. The instant invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.
