  • Polycyclic polymers containing pendant cyclic anhydride groups
    Patent number: 6525153
    Abstract: Polymers comprising polycyclic repeating units containing pendant anhydride moieties are disclosed. The polymer can be polymerized from polycycloolefins containing pendant anhydride moieties in the presence of a nickel containing single component catalyst. In optional embodiments the polycycloolefin monomer containing the pendant anhydride functionality can be copolymerized with other polycycloolefin monomers that contain pendant functional groups to yield random copolymer products.

  • Photoresist compositions comprising polycyclic polymers with acid labile pendant groups
    Patent number: 6232417
    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.
