  • Photo-imageable compositions of norbornene and acrylate copolymers and use thereof
    Patent number: 7087691
    Abstract: Embodiments in accordance with the present invention encompass photo-imageable compositions that include polymers of acrylate-type monomers and norbornene-type monomers. In some embodiments a catalyst system comprising a cationic or a neutral Pd(II) dimer component having the formula (Allyl)Pd(P(R21)3) or (L?)[(L)Pd(R)(X)]2, respectively is employed to effect polymerization. In other embodiments a free radical or living free radical catalyst is employed to effect polymerization. At least one of the acrylate-type monomers and norbornene-type monomers of the polymer embodiments of the present invention encompass an acid labile moiety. Some polymer embodiments of the present invention include more than one type of acrylate-type monomer and norbornene-type monomer. Embodiments of the present invention include forming a patterned layer on a substrate and some embodiments include transferring the patterned structure to a material layer first formed on the substrate.
