Title:
NOVEL POLYMER CONTAINING SATURATED CYCLIC MOLECULAR STRUCTURE UNITS
Document Type and Number:
WIPO Patent Application WO/1994/029359
Kind Code:
A1
Abstract:
A polymer containing saturated cyclic molecular structure units, wherein the main chain is represented by general formula (I) and which has a number-average molecular weight of 10,000 to 500,000, wherein A to F represent each a monomer unit constituting the main chain and may be arranged in an arbitrary order; a to f represent the weight percentages of the respective monomer units A to F based on the total weight of the polymer; A represents a cycloolefin monomer unit; B represents a cyclic conjugated diene monomer unit; C represents a chain conjugated diene monomer unit; D represents a vinylaromatic monomer unit; E represents a polar monomer unit; F represents an ethylene and/or a alpha-olefin monomer unit; 0.001 a 100, 0 b < 100, 0 c < 100, 0 d < 100, 0 e < 100, and 0 f < 100; provided the content of the monomer unit A is 0.1-100 mole% based on the total content of the monomer units A and B. The polymer is excellent in thermal and mechanical properties. It can be advantageously produced by preparing a cyclic conjugated diene polymer containing the monomer units B, C, D, E and F preferably in the presence of a specified polymerization catalyst, and subjecting the obtained polymer to addition reaction to convert the cyclic conjugated diene monomer units into a saturated cyclic molecular structure.
