  • Patent number: 6423780
    Abstract: In accordance with the present invention, there are provided novel heterobifunctional monomers and uses for the same. Invention compounds have many of the properties required by the microelectronics industry, such as, for example, hydrophobicity, high Tg values, low dielectric constant, ionic purity, low coefficient of thermal expansion (CTE), and the like. These properties result in a thermoset that is particularly well suited to high performance applications where typical operating temperatures are often significantly higher than those at which prior art materials were suitable. Invention compounds are particularly ideal for use in the manufacture of electronic components, such as, for example, printed circuit boards, and the like.

  • 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.

  • Publication number: 20020068803
    Abstract: The present invention relates to a copolymer resin for a photoresist used in far ultraviolet ray such as KrF or ArF, process for preparation thereof, and photoresist comprising the same resin. The copolymer resin according to the present invention is easily prepared by conventional radical polymerization due to the introduction of mono-methyl cis-5-norbonen-endo-2,3-dicarboxylate unit to a structure of norbornene-maleic anhydride copolymer for photoresist. The resin has high transparency at 193 nm wavelength, provides increased etching resistance and settles the problem of offensive odor occurred in the course of copolymer resin synthesis. Further, as the resin composition can be easily controlled due to the molecular structure, the resin can be manufactured in a large scale.

  • Patent number: 6384162
    Abstract: A process for production of an ethylene-propylene-diene-methylene (EPDM) tetrapolymer having long chain branching is described. The process comprises the step of polymerizing a monomer mixture comprising ethylene, propylene, a first diolefin monomer containing one polymerizable double bond (preferably ENB) and a second diolefin containing two polymerizable double bonds (preferably VNB) in the presence of a catalyst system. The catalyst system comprises: a catalyst comprising a compound containing vanadium +3 with the proviso that the compound does not comprise a halogen directly bound to the vanadium; a halogenated organoaluminum cocatalyst having a halogen to aluminum molar ratio in the range of from about 1 to about 2; and an activator. The branched polymer product of the present process exhibits a molecular weight distribution of less than about 3.5 and improved rheological properties and enhanced processability characteristics.
