Title:
ノルボルネン系重合体及びその製造方法
Document Type and Number:
Japanese Patent JP4174968
Kind Code:
B2
Abstract:
A norbornene polymer comprising a repeating unit derived from a norbornene monomer having a cyclic hydrocarbon structure (I) derived from the norbornene ring which constitutes at least a part of the main chain, another cyclic hydrocarbon structure (II), which shares one carbon-carbon bond with the cyclic hydrocarbon structure (I) and has 4 to 6 carbon atoms, and a monocyclic or polycyclic hydrocarbon structure (III), which shares one carbon-carbon bond with the cyclic hydrocarbon structure (II), in a proportion of 20 to 100 mol% based on the whole repeating unit of the polymer, wherein the number average molecular weight is within a range of 1,000 to 1,000,000, and a peak area (A) on a high magnetic field side and a peak area (B) on a low magnetic field side in methylene peaks derived from the methylene groups in the cyclic hydrocarbon structure (III) in a <13>C-NMR spectrum as determined in heavy chloroform (TMS standard) satisfy a relationship of the expression:
