Abstract
Disclosed is a polymer containing a cyclic olefin monomer unit, comprising a main chain represented by the formula: ##STR1## wherein A to F are monomer units constituting the main chain in which A to F are arranged in any order, and a to f are, respectively, weight percentages of A to F, based on the total weight of A to F; A to F are selected from cyclic olefin monomer units, cyclic conjugated diene monomer units, chain conjugated diene monomer units, vinyl aromatic monomer units, polar monomer units, and an ethylene monomer unit and α-olefin monomer units, respectively; and a to f satisfy the following requirements: 0.001≦a≦100, and 0≦b, c, d, e, f≦100, with the proviso that monomer unit A is present in an amount of from 0.1 to 100 mole %, based on the total number of moles of the monomer units A and B, wherein when a=100, depending on whether the A monomer units are comprised of same or different cyclic olefin monomer units, the polymer has a number average molecular weight (Mn) of from 10,000 to 5,000,000 or from 1,000 to 5,000,000, and wherein when 0.001≦a+b<100, the polymer has an Mn of from 500 to 5,000,000. This polymer has excellent thermal and mechanical properties. The polymer can be advantageously produced by a method in which a cyclic conjugated diene polymer is synthesized, preferably using a specific polymerization catalyst, and the obtained polymer is subjected to an addition reaction to thereby convert a cyclic conjugated diene monomer unit to a cyclic olefin monomer unit.
