    摘要: A method of polymerizing poly(cyclic)olefin monomers encompassing (a) combining a monomer composition containing the poly(cyclic)olefin monomers, a non-olefinic chain transfer agent and an activator compound to form a mixture; (b) heating the mixture; and (c) adding a polymerization catalyst containing Ni and/or Pd. The non-olefinic chain transfer agent includes one or more compounds selected from H2, alkylsilanes, alkylalkoxysilanes, alkylgermanes, alkylalkoxygermanes, alkylstannanes, and alkylalkoxystannanes. The activator is characterized as having an active hydrogen with a pKa of at least 5. The resulting poly(cyclic)olefin polymers can be used in photoresist compositions.

    摘要: Embodiments in accordance with the present invention encompass methods of forming in situ olefin polymerization catalyst systems, catalysts encompassed by such systems and polymers made using such systems. For such in situ olefin polymerization catalyst systems, a hydrocarbyl magnesium halide is generally contacted with a halohydrocarbyl compound to form a halohydrocarbyl Grignard and such Grignard is generally contacted with a Group 10 metal compound to form an olefin polymerization catalyst which is contacted with one or more olefin monomers to form a polymer therefrom.
