  • Publication number: 20080103273
    Abstract: A process of synthesizing hyperbranched polytriazoles, linear and hyperbranched poly(aroyltriazoles) by Huisgen 1,3-dipolar cycloaddition. The polytriazoles were prepared by A2+B3 method to avoid self-polymerization during monomer preparation and storage. The polymers are light emissive and can be crosslinked to generate well-resolution photopatterns upon UV irradiation. White light emission patterns were observed with fluorescence microscopy. The high molecular weight poly(aroyltriazoles) (up to 26000 Da) are prepared in high yields (up to 92.0%) and with high regioselectivity (the ratio of 1,4- and 1,5-disubstituted 1,2,3-triazole is equal or larger than 9:1). The polycyclomerization is not moisture or oxygen sensitive and therefore, no special precautions are necessary before and during the reaction. All the polymers are processible, easily film-forming, and curable into thermosets by heat or irradiation. The hyperbranched polymers can act as fluorescent adhesive materials with large tensile strength.

  • Publication number: 20030003379
    Abstract: Photoresist monomers of following Formula 1, photoresist polymers thereof, and photoresist compositions containing the same. The photoresist composition has excellent etching resistance, heat resistance and adhesiveness to a wafer, and is developable in aqueous tetramethylammonium hydroxide (TMAH) solution. In addition, the photoresist composition has low light absorbance at 157 nm wavelength, and thus is suitable for a photolithography process using ultraviolet light sources such as VUV (157 nm) in fabricating a minute circuit for a high integration semiconductor device.

  • Patent number: 6492449
    Abstract: The present invention concerns polymers obtained by anionic initiation and bearing functions that can be activated by cationic initiations that are not reactive in the presence of anionic polymerization initiators. The presence of such cationic initiation functions allow an efficient cross-linking of the polymer after moulding, particularly in the form of a thin film. It is thus possible to obtain polymers with well-defined properties in terms of molecular weight and cross-linking density. The polymers of the present invention are capable of dissolving ionic compounds inducing a conductivity for the preparation of solid electrolytes.

  • Patent number: 6486279
    Abstract: Activation of ruthenium based catalyst compounds with acid to improve reaction rates and yields of olefin metathesis reactions, including ROMP, RCM, ADMET and cross-methasis reactions is disclosed. The ruthenium catalyst compounds are ruthenium carbene complexes of the general formula AxLyXzRu═CHR′ where x=0, 1 or 2, y=0, 1 or 2, and z=1 or 2 and where R′ is hydrogen or a substituted or unsubstituted alkyl or aryl, L is any neutral electron donor, X is any anionic ligand, and A is a ligand having a covalent structure connecting a neutral electron donor and an anionic ligand. The use of acid with these catalysts allows for reactions with a wide range of olefins in a variety of solvents, including acid-initiated RIM processes and living ROMP reactions of water-soluble monomers in water.

  • Publication number: 20020128408
    Abstract: The present invention relates to a radiation sensitive photoresist composition comprising a photoacid initiator and a polycyclic polymer comprising repeating units that contain pendant acid labile groups. Upon exposure to an imaging radiation source the photoacid initiator generates an acid which cleaves the pendant acid labile groups effecting a polarity change in the polymer. The polymer is rendered soluble in an aqueous base in the areas exposed to the imaging source.

  • Patent number: 6420503
    Abstract: The invention is directed to polymers containing a repeating unit derived from a norbornene sulfonamide. These may be addition polymers which include copolymers with one or more comonomers such as norbornene, ethylene, an acrylate or sulfur dioxide or carbon monoxide. Said monomers may be polymerized using single or multicomponent Group VIII catalysts. The norbornene sulfonamides can also form ROMP polymers using known metathesis catalysts. Preferably the ROMP polymers may be hydrogenated to give more stable polymers.
