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 H

, 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.
一种聚合多(环)烯单体的方法,包括(a)将含有多(环)烯单体、非烯烃链转移剂和活化剂化合物的单体组合物混合形成混合物;(b)加热混合物;和(c)添加含有Ni和/或Pd的聚合催化剂。非烯烃链转移剂包括从H2、烷基硅烷、烷基烷氧基硅烷、烷基锗烷、烷基烷氧基锗烷、烷基锡烷和烷基烷氧基锡烷中选择的一种或多种化合物。活化剂的特征是具有至少5的pKa值的活性氢。得到的多(环)烯聚合物可以用于光阻组合物。
