    摘要: A method for preparing a cyclic olefin addition polymer of high gas permeability, which method including subjecting a specific type of cyclic olefin-functional siloxane and a mixture thereof with a specific type of cyclic olefin compound to addition polymerization in the presence of a multi-component catalyst containing (A) a zero-valent palladium compound, (B) an ionic boron compound, and (C) a phosphine compound having a substituent group selected from an alkyl group having 3 to 6 carbon atoms, a cycloalkyl group and an aryl group, to obtain a cyclic olefin addition polymer of high gas permeability wherein a ratio of the structural units derived from the cyclic olefin-functional siloxane is at 10 to 100 mole% of the addition polymer and a number average molecular weight (Mn) ranges from 100,000 to 2,000,000.
