    摘要: A method of controlling the molecular weight of poly(cyclic) olefin (norbornene-type) polymers and activating the polymerization thereof with a single material is provided. Such method include adding a chain transfer/activating agent to a mixture of monomer(s), catalyst, solvent and an optional cocatalyst and polymerizing the mixture to form a polymer. It is shown that the amount of chain transfer/activating agent in the mixture can serve to control the molecular weight of the resulting polymer, its percent conversion or both, and in some embodiments the optical density of the resulting polymer.

    摘要: 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.
